Moth Report, 10 November 2020
I put the trap out last night on the spur of the moment, perhaps with a view to attracting a November Moth in mind, and had just three moths (interestingly, two of them on the sheet). It turned wet and windy during the night which wouldn’t have helped. Among the three were December Moth, which is new for me, although common, but I have rarely trapped this late in the year previously.
The December Moth is a rather smart moth which I was pleased to see. It belongs to the same family as the Lappets and Eggars (we had Lappet and Oak Eggar last year in the Community Woodland), furry, thickset moths. None of this family is able to feed as adults. Despite its name, the December Moth hasn’t really appeared early – its flight season is late October to January.
Another Mottled Umber turned up and I have put its photo alongside the one which came to the light a few days ago, just to show the great variation which this species demonstrates. The recent moth (on the left), with clear wing markings, is perhaps the more typical.

The third moth was Red-line Quaker, which I am learning to respect as a moth not to be defeated by British weather!
Moth Report, 7 November 2020
This spell of quiet and relatively mild weather has provided an opportunity to see what moths may be flying this late in the year. Obviously, numbers will be fewer, as moths hunker down for the winter or, more commonly, overwinter as eggs, caterpillars or pupae, but there are some around, and suitably enough, in autumn colours. So here are some pictures of three species which came to my trap on Saturday night.
Mottled Umber (male)
Mottled Umber is a highly variable moth, so don’t be surprised if you see illustrations in moth guidebooks very differently marked. This individual is a rather plain form – others have much more noticeable wing markings. All of them that come to light are males. The females are wingless and wait for a male to find them – a not uncommon strategy which must be effective because it is shared by a number of the commonest moths.
Feathered Thorn can join the other Thorns we have seen this year. Before the lockdown, we saw all the Thorns you could reasonably expect to see (August/September, Canary-shouldered, Dusky, Early) in the Community Woodland. Four individuals came to the trap, I have pictured two of them to show a degree of variation.
Dark Chestnut (probably)
The Chestnuts are appropriately named characteristic autumn moths. These two individuals are, I think, Dark Chestnut, but the Chestnut is very similar and so the ‘probable’ appellation is a get-out. But they are one or the other (and have a rather fine head of hair!).
I was hoping to attract the ‘moth of the month’ – the November Moth – though without success. But, along with the Autumnal Moth, Winter Moth and a number of related moths – all very similar and all flying late in the year as their names suggest – there is still scope to see at least one or two of this group of moths.
The full list (11 moths of 7 species) is: Common Marbled Carpet, Dark Chestnut (prob. x2), Feathered Thorn (x4), Lesser Yellow Underwing, Mottled Umber (male), Red-line Quaker and Silver Y.
Moth Report, 18 October 2020
The mothing season is tailing off now, so I put the trap out on Sunday night more in hope than expectation, especially as it was quite chilly, although not windy. Nevertheless, I was pleased with the selection of autumn moths that resulted. Nothing rare, but some handsome moths.
Chief among them was a Merveille du Jour, a beautiful green moth – an unusual colour for a moth. Its striking colour and pattern is in fact an excellent camouflage against the powdery green algae or lichen on the bark of an oak tree, its larval food plant.
Merveille du Jour
Another green(ish) moth is the Green-brindled Crescent. It is beautifully marked with a dusting of brilliant ‘metallic’ green scales. Seen ‘in the flesh’ in a good light, it is really quite spectacular. With larval food plants which include hawthorn and blackthorn, as well as many other woody hedgerow and garden trees and shrubs, it is not uncommon, although apparently much declined in recent decades.
Quite a few moths active at this time of year naturally have the colours of autumn leaves and one such is the Beaded Chestnut. This is another common moth said to have severely declined in recent years, although there were three in the trap. The larvae feed on a variety of common grassland ‘weeds’, of which there are a lot in our neighbourhood, so not a surprise to see this characteristic autumn moth.
The Quakers (moths) are named with reference to the modest clothing historically worn by Quakers. Some might call them drab, but I think, like many apparently plain moths, they have a subtle beauty. There are two groups of moths with the vernacular name of Quakers, most of which are springtime flyers, but the Red-line Quaker (together with its close relative the Yellow-line Quaker) are active late into the year.
We can expect the life-cycles and flight periods of moths to be strongly affected by climate change and the more extreme weather patterns we are experiencing – always remembering that the emergence of the adult depends on the conditions the larvae have experienced over a whole year, or longer.
The full list (15 moths of 10 species) is: Beaded Chestnut (x3), Black Rustic (x2), Common Marbled Carpet, Green-brindled Crescent, Grey Shoulder-knot, Lesser Yellow Underwing (x2), Lunar Underwing, Merveille du Jour, Red-line Quaker (x2) and Shark (well outside flight season?).

Moth Report, 14 September 2020
Despite a warm, still night, the results of 14 September were slightly disappointing. The most obvious feature was the proportion of Lunar Underwing – virtually a third of the total. As it happened, the first I started to identify was a rather worn specimen so it took some time to id itbefore I cottoned on, but from then on Lunar Underwing accounted for most of the lbjs in the trap. Although variable in colour, it is a perfectly distinctive moth once you get your eye in.
Another nice moth that came to the trap is the Chinese Character. I have previously referred to moths which display bright yellow or red and black markings, widely used throughout the insect world to signal toxicity, and those non-toxic moths which mimic those that are. Another form of mimicry is well shown by this tiny, and deliberately inconspicuous moth, which is not at all uncommon. The Chinese Character (Cilix glaucata) is only about a centimetre long when at rest, holding its wings up like a sort of hood, and looks exactly like a bird dropping – perhaps more so in reality than demonstrated in the photo below.
But looked at closely, it is really rather a beautiful moth, finely marked and textured – the Chinese bit of its name could just as easily stand for the finest Chinese porcelain – although it is the markings on the wing which are sometimes suggestive of a Chinese ideogram. It is regularly attracted to light and its larvae feed on a variety of common hedgerow trees.
The full list (29 moths of 13spp) for 14 September is: Brimstone, Chinese Character, Common Wainscot (x2), Dusky Thorn (x2), Green Carpet, Large Yellow Underwing (x3), Light Emerald, Lunar Underwing (x9), Oak Hook-tip, Ruby Tiger, Setaceous Hebrew Character (x2), Snout and Square-spot Rustic (x4) .
There are currently a lot of Silver Y around in the daytime, but there was an absence of immigrants in the trap.
Moth Report, 31 August 2020
Some visitors to the trap on 31 August included three seasonal moths in very fine condition. The first is August Thorn – or possibly, September Thorn. Unfortunately, the month in the name is no guide to the identification of these very similar moths, both of which fly in the late summer/early autumn, but I’m fairly certain the first moth is an August Thorn.
The next two pictures are Dusky Thorn; again, very similar but distinguished by a darker marking on the wing. All the Thorns are characterised by their rather unusual resting posture with the wings held up at an angle reminiscent of a butterfly. Both these individuals are males with splendid antennae.
The fourth is Light Emerald – strictly speaking not a true Emerald, although there cannot be strict rules for vernacular names. But all the other Emeralds are a different family (and a brighter green) and the Light Emerald is actually the same family as the Thorns. Anyway, whatever its name, a lovely moth and like the Thorns, in very good condition.
I don’t know if it’s my imagination, but a number of moths and butterflies seem large and fine this year. We’re used to speaking of good and bad butterfly and moth years based on the adults we see flying, but need to remember that what matters most is how the larvae fared, usually for the previous year or more, and that while we may grow nectaring flowers to be helpful for the adults (or at least those which actually feed) and more especially to increase our chances of seeing them, it is the supply of food plants for the larvae which is critical. And as many of these are commonly regarded as weeds, we have a typical human inconsistency of carefully growing certain flowers to attract the adult while ruthlessly eliminating the plants on which their feeding stages depend. We have been encouraged to allow some nettle patches but I wonder when our tolerance will extend to Docks, which are very important food plants for many moth caterpillars!
The full list (45 moths of 15 spp) for 31 August is: August Thorn, Brimstone, Common Wainscot (x14), Dusky Brocade? (x2), Dusky Thorn, Flounced Rustic (x2), Large Yellow Underwing (x6), Lesser Broad-bordered Yellow Underwing, Light Emerald (x2), Orange Swift, Rosy Rustic, Rustic, Setaceous Hebrew Character (x7), Siver Y (x3) and Small Square-spot (x2).
I have queried the Dusky Brocade as Brocades can be problematic to identify and Dark Brocade was another possibility. Nutmeg is a similar moth, but lacks the strong ‘W’ at the end of the wing.
Moth Report, 16 August 2020
A fine pair of Red Underwing settled on our house wall last night, Sunday 16 August.
This large moth is not rare and can sometimes be seen by day, either nectaring or resting, and when it exposes its red and black hindwing, its identity is obvious. Its food plants include willows and poplars, so you would expect it about here.
This is one of numerous butterflies and moths which display a red or yellow and black warning signal to would-be predators. These colours are intended to signal that the insect is toxic and distasteful. The more insects which display them, the more the message is learnt and understood by predators, so they mimic each other and the signal becomes very widespread – known as Mullerian mimicry.
This system only works, of course, if the majority are actually distasteful: otherwise the system would lose its potency. In fact, some non-toxic, tasty insects do mimic toxic, nasty ones, without going to the trouble of making toxins – known as Batesian mimicry. So there is a limit to this ‘free-loading’ behaviour which would become self-defeating if too common.
This was first realised and described by the naturalist Henry Walter Bates, who explored and collected in the Amazon with his companion Alfred Russel Wallace. Both were outstanding naturalists and explorers and Wallace arrived at an understanding of evolution through natural selection while working in Borneo.
Wallace wrote to Charles Darwin – who he regarded as a senior naturalist likely (and broad-minded enough) to be understanding of his ideas – not knowing that Darwin had been maturing the same theory for many years but never published. This led to a joint presentation to the Linnaean Society of a summary Darwin had prepared for his closest friends some years previously and Wallace’s letter.
This was the first public announcement of evolution by natural selection but it went virtually unnoticed. It was not until Darwin published On the Origin of Species in 1859 that its importance began to dawn on people.
Silver Y is another day-flying moth in evidence at the moment. If you see a medium-sized grey job behaving like a butterfly on your flowers, it is likely to be a Silver Y. The silver mark which gives it its name is clearly visible on the forewings, but can only be seen when the moth is still– which it rarely is – when nectaring it beats it wings very fast. Silver Y is an immigrant which (at the moment at least) cannot sustain its life-cycle over our winter.

Moth Trapping, 2 August 2020
The highlight of the night was undoubtedly the number of Jersey Tiger. I had similar numbers in August last year. The most recent edition of Townsend and Waring’s Concise Guide to the Moths of Great Britain and Ireland still describes Jersey Tiger as ‘local’ (and also an immigrant) but clearly there is a well-established population here. The Somerset Moth Recorder said he had similar records last year. Altogether, North Curry seems good for Tiger moths, although I am still waiting for Garden Tiger.
At least one of the Jersey Tigers was the rarer form with the yellow underwing.
Although there is nothing rare or even unusual about them, three species were new to me: Latticed Heath; Shaded Broad-bar and Straw Underwing. This will simply be down to location and habitat, or simply the vagaries of mothing.
The forewings of Straw Underwing are Brocade-like and, as it was new to me, I was puzzling over it until I thought to look at the hind wing. It is useful to bear this in mind if you have what you think might be a Brocade of sorts.
The full list (85 moths of 32 spp.) was: Blood-vein, Brimstone (>5), Cloaked Minor (x2), Common Carpet (x2), Common Footman (x3), Common Rustic (x5), Common Wainscot (x5), Drinker (M), Dusky Thorn (x3), Elephant Hawkmoth, Flame Shoulder (x2), Garden Carpet, Iron Prominent, Jersey Tiger (>13), Latticed Heath, Lesser Broad-bordered Yellow Underwing (>11), Lime-speck Pug, Lychnis, Magpie (x2), Marbled Green, Oak/Northern Eggar (F) (x2), Pale Prominent, Pebble Prominent, Ruby Tiger (x2), Rustic (x3 incl. poss. Vine’s Rustic), Shaded Broad-bar, Shuttle-shaped Dart (x5), Spectacle, Straw Underwing (x2), Willow Beauty (x4) and Yellow-tail (x2).
Moth Trapping, 25 July 2020
Despite a spell of poor weather, I put the trap out on Saturday night, 25 July, just to see if the rain showers had tempted any moths out, though it was not a full night’s trapping as I closed the trap down at 2 am. Nevertheless, I caught some interesting and varied moths, including Common Footman (quite a number, not counted), Common Rustic (x2), Dark-barred Twin-spot Carpet, Dingy Footman, Drinker (M), Jersey Tiger, Knot Grass, Lesser Broad-bordered Yellow Underwing, Nutmeg (x3), Pale Prominent, Pebble Prominent, Riband Wave, Ruby Tiger (x4, one nearly black) and Willow Beauty (14 species).
The Dingy Footman is quite a distinctive moth, much broader and more curved than the Common Footman. The Lesser Broad-bodied Yellow Underwing was very fresh and showed well the pale green collar which helps identification. The Nutmegs were pristine specimens. The Ruby Tigers are obviously out in force now, and one I had was virtually a velvety black, but bright red underneath of course.
The male Drinker Moth has enormous and splendid antennae. Many male moths have big feathery antennae to discern the female pheromone, of course, but this male Drinker has super-sized antennae. The photo below was snapped in a hurry before it flew off. A moth which has been cold overnight will vibrate for a minute or two to warm itself up and get its muscles working before flying off. This moth is doing just that, which is why the wings are blurred.
Male Drinker moth, showing fine antennae
The Pale Prominent is shown below. Cryptic scarcely describes this moth which when at rest looks exactly like a scrap of thin bark or other debris. If it feels threatened, it will flatten itself and become remarkably thin, keel over on its side and feign death. Like this, it certainly doesn’t look like anything worth eating, and I almost missed it when I was checking the trap, mistaking it at first for a scrap of rubbish.

Moth Trapping, 11 July 2020
A respectable tally for July on the first relatively wind-free night we have had for some time. Allowing for the numerous Common Footmen, Rustics and Heart & Dart, there were about 50 moths of 20 species, including Barred Straw, Buff Arches, Buff Ermine (M & F), Common Footman (very many), Common Rustic, Dark Arches (x3), Elephant Hawkmoth, Heart & Dart, Large Yellow Underwing, Mottled Rustic (prob.), Nut-tree Tussock, Pale Mottled Willow?, Riband Wave, Ruby Tiger, Rustic/Uncertain, Scalloped Oak (x2), September Thorn (prob), Yellow-tail, Shark, Willow Beauty (prob., very worn).
Some pictures from the night include a Yellow-tail, which is obvious in this picture but not when the tail is hidden, as it normally is when the moth is not irritated.
Yellow-tail showing tail
The yellow hairs are themselves an irritant and the female (the photo is a male) mixes them with her eggs when she lays them. There is a close relative – the Brown-tail – which is virtually identical but with, obviously, brown hairs. These are very irritating and can be carried in the air, which is not usually a problem except in exceptional years when the Brown-tail has a population surge. The caterpillars live communally in large webs which can completely envelop their food plant, normally a hedgerow tree or shrub. When this happens, they are very noticeable and can make people, and particularly local authorities, extremely anxious as they try to ‘close’ hedges, egged on by the tabloids. But it is worth remembering that a number of caterpillars have irritant hairs as a defence against predators which they incorporate into both their eggs and pupae.
The next picture is a Buff Ermine, a member of the same family of largely furry and stocky moths, including Tiger Moths. This is the male, which is buff; the female has a pure white background with similar markings.
Buff Ermine male
Another fine moth is the Scalloped Oak.
The next two moths are so common they are often neglected. The Riband Wave is known to every moth trapper. It is a very variable summer (and sometimes autumn) moth, but the basic pattern of lines is always consistently present and helps distinguish it from the many other Waves, which can be a rather difficult group to identify.
The Common Footman is particularly abundant at the moment: it made up about half of the total moths which were trapped last night, and there will have been many more that were attracted to the light but not trapped. As with the Waves, there are a number of Footman species which look superficially similar, but all rather smart, if sombre, as befits a good footman.
Moth Trapping, 23 June 2020
I put the trap out in my garden on Tuesday night 23 June and trapped 33 moths of 21 spp. The full list was: Barred Straw, Brimstone, Broad-barred White, Brussels Lace (m, very dark), Buff Ermine (x4), Buff Footman? (very clear and strong orange margin), Common Footman, Common Rustic, Dark Arches (x6), Elephant Hawkmoth (x2), Heart & Dart (x5), Large Yellow Underwing (x2 trapped, but more blundering about), Leopard Moth, Minor, Mottled Rustic?, Orange Moth (x2 m), Poplar Hawkmoth, Puss Moth, Small Elephant Hawkmoth, Snout and Willow Beauty.
The Poplar Hawkmoth is a fine moth. For some reason, I never find a tatty, worn one: they always seem to be fresh.
The Leopard Moth is a common moth but the first time I have seen it. It is one of a family of moths of which the adults cannot feed and the larvae are tunnellers. So, three years as a caterpillar inside a willow tree, and a week or so flying around hungry looking for a mate!
Orange Moth (so named for obvious reasons), again not rare, but local and another first for me. With two in one night, there must be a breeding population nearby. In contrast to the Poplar Hawkmoth, this is an extremely flighty moth, and the photo is of the slightly less tatty of the two.
Moth Trapping, 27 May 2020
With the year moving on and an exceptional spell of warm and, above all, calmer weather, the moth count is increasing. On the night of Wednesday 27 May Stephen had 20 spp., 35 moths in all (as always, not including micro-moths or pugs, unless the latter are very easy!). This is not a high count but a good average for this time of year.
Moth numbers at traps can be very unpredictable and inconsistent. The full list was: Barred Straw (x2), Brimstone, Buff-tip, Common Carpet (x2), Common Marbled Carpet, Common Swift, Common Wainscot (x2), Cream-spot Tiger, Elephant Hawkmoth, Garden Carpet, Green Carpet (f), Heart and Dart (x6), Light Emerald, Lychnis, Marbled Minor, Pale Tussock (x2m), Puss Moth, Treble Lines (x5), White Ermine (x2m), Willow Beauty (x2) (plus Small Magpie, a micro-moth).
One interesting moth was the Light Emerald - strictly speaking not a ‘true’ Emerald in the sense that it is a different family from all the other Emeralds, which are stronger green. But green is an unusual colour for moths and the Light Emerald is nice to see, although common, with a larva which feeds on a wide variety of broad-leaved trees and shrubs.
And, by way of contrast, a Lychnis, which initially looks a bit of a plain brown moth but has quite a distinctive ‘x’ pattern on its resting wings.
Another Puss Moth turned up and laid eggs - which look to be fertile so Stephen will try to rear them for the unusual and spectacular caterpillar.
Moth Trapping, 20 May 2020
Stephen put the trap out in his garden on Wednesday 20 May with good results. Honours were shared between three Cream-spot Tigers, a Puss Moth and a Buff-tip. The three Cream-spot Tigers were caught in quick succession when they settled on the backing sheet while Stephen was checking the trap at 10.30pm. This might indicate that there is a good population locally.
Quite a few moths are attracted by the light of a moth trap, but do not necessarily enter the trap. On a pleasant summer night, it is worth staying up and picking moths off the sheet as they arrive. Indeed, on a good night it might be worth simply shining a bright light on a white sheet and seeing what turns up.
Another nice moth was Puss Moth. It has the most spectacular larva, which a recent article in British Wildlife suggests is a snake mimic - a geologically ancient fear of snakes being genetically in-built in almost all animals. The food plant is willow so it may be common locally.
The third moth, the Buff-tip, is an astonishing mimic of a broken twig.
Altogether, there were 24 moths of 14 species, quite a respectable total for this time of year. The full list was: Buff-tip, Cream-spot Tiger (x3), Garden Carpet, Heart & Dart (x5), Hebrew Character, Knot Grass, Lychnis, Muslin Moth (m), Pale Tussock (m & f), Puss Moth, Shuttle-shaped Dart, Treble Lines (x4), White Ermine (m), Yellow-barred Brindle.
Moth Trapping, 9 May 2020
Stephen put the trap out on Saturday 9 May in his garden as a still, warm night was forecast, resulting in a catch that was diverse, if not numerous (11 moths of 11 species): Brimstone, Broken-barred Carpet, Common Marbled Carpet, Cream-spot Tiger, Dark-barred Twin-spot Carpet, Heart and Dart, Hebrew Character, Pebble Prominent, Shuttle-shaped Dart (F), Streamer and Treble Lines.
Stephen was particularly pleased to attract the Cream-spot Tiger, which was placidly sheltering behind the backing sheet. While it is not rare (it is classed as ‘local’), he has no record of seeing it before in the UK, so it was a nice find. Like all Tigers, it is on the flamboyant side due to its typical warning colouration.

The Cream-spot Tiger is a moth which will rest quite visibly during the day, relying on its warning colouration to deter predators, so it worth keeping an eye open at the base of hedgerows.
Another Tiger which will rest in plain view during the day, and might at first glance be confused with the Cream-spot, is the Jersey Tiger which has been seen at the woodland and may be seen in gardens in summer.

Moth Trapping, 24 April 2020
Stephen put the trap out in his garden again and trapped 5 moths of 5 species, including two moths characteristic for this time of year: the Muslin Moth (below left) and the Pale Tussock (below right ). Both are males as you can see from their fine antennae.
The female Muslin Moth has the same markings, but a totally different, white, ground colour. The Pale Tussock is showing his characteristic resting posture with furry forefeet pushed forward. Both species are often very placid moths which, if attracted to light and not disturbed, will rest like that for long periods.
Moth Trapping, 2 April 2020
Stephen put the moth trap out on 2 April in his garden for the first time since the autumn (conditions over the winter had been so wet and, above all, windy as to make it not worthwhile). Conditions were far from ideal and there was just one moth in the trap: a Hebrew Character, one of the early spring moths and a common one, but new to our list simply because of the time of year. The name derives from the apparent resemblance of its wing marking to a character in the Hebrew alphabet.
Later in the day, Stephen noticed another common spring moth, Common Quaker, which was probably attracted to the light but not trapped. Its name refers to the very plain, not to say drab, appearance of this moth, reminiscent of sombre Quaker dress.
Moth Trapping, Winter 2019-2020
We had intended to continue setting the moth trap throughout the winter at the Community Woodland, but incessant rain and wind prevented this. Nevertheless, Stephen encountered his first ‘proper’ moth of the year in his greenhouse on 29 February, the very attractive Angle Shades. This is a moth which has been recorded in every month of the year, probably with two broods and some immigrants, but this one was pristine and very early.
Report of moth trapping at the Community Woodland, 27 September 2019 (National Moth Night)
Text and photos by Stephen Locke
This was a quiet but worthwhile trapping and our contribution to National Moth Night at a time of inauspicious weather. We were grateful to the Met Office for the accuracy of their forecast which allowed us to choose the one reasonable evening of the three designated as Moth Nights. The wind died down and it was a clear night, chilly rather than cold (about 12 deg). Warmer and overcast would have probably encouraged more moths.
Nevertheless, among the small number attracted, we had several characteristic and distinctive autumn moths, including Sallow, Barred Sallow and, in the same family, Lunar Underwing, of which we had at least half-a-dozen specimens.
Sallow (left) and Barred Sallow (right)
These join the Centre-barred Sallow which we had at the Community Woodland on 8 September (see below). All of them are moths of grassland, scrub, hedgerows and broad-leaved woodland and are autumn flyers, so they are just what you would expect.
Setaceous Hebrew Character, a very common and distinctive moth, was the most numerous moth of the night, although it was followed closely by the Lunar Underwing.
Setaceous Hebrew Character (left) and Lunar Underwing (right)
The full list was: Barred Sallow, Garden Carpet, Lunar Underwing, Sallow, Setaceous Hebrew Character and a Beauty (prob. Willow Beauty but too worn for confident id) (6 spp.), along with several very worn and unidentifiable LBJs.

Text and photos by Stephen Locke
We ran the trap between 8.15 and 10.30 pm, with most activity occurring between 9 and 10 pm, but the results were rather sparse with just nine species recorded. The strong, three-quarter moon in a largely clear sky may have been a factor. Moonlight is often said to reduce catches, but since results often seem inconsistent it is not really possible to say.
The list that follows, however, does include two colourful and characteristic autumnal moths: Canary-shouldered Thorn and Centre-barred Sallow. The Canary-shouldered Thorn is aptly named, and all the common species of Thorn have now been recorded at the Community Woodland.
The larvae of the Centre-barred Sallow, despite its name, feed on the unopened buds of mature ash; those of the Canary-shouldered Thorn on a variety of trees.
The full list of moths seen is: Brimstone, Canary-shouldered Thorn, Centre-barred Sallow, Common Wainscot, Dusky Thorn, Grey Chi, Large Yellow Underwing, Setaceous Hebrew Character (the name of this very common moth refers to the wing markings resembling a Hebrew letter), Square-spot Rustic (probably the most abundant moth of the night and a real LBJ!) (9 spp)

This session in a central North Curry garden produced a very good variety of moths. We ran the trap between 8.30 and 11.30 pm, with most activity being between about 9.15 and 11.00 pm, but there was plenty going on when we packed up.
Gold Spot (left) and Jersey Tiger (right)
The list of moths seen is: August Thorn, Blood Vein, Brimstone (many), Chinese Character (looks like a conventional moth with its wings open - small, white with black markings - but an excellent mimic of a bird-dropping when at rest), Common Carpet, Common Footman (many), Common (or Dark) Marbled Carpet, Common Rustic, Common Wainscot (many), Dog’s Tooth, Flame Shoulder, Gold Spot, Green Carpet (fresh - they lose their green colour as they age), Jersey Tiger, Large Yellow Underwing (many), Lesser Broad-bordered Yellow Underwing (many), Light Emerald, Orange Swift, Poplar Hawkmoth (a truly noble moth), Rustic, Setaceous Hebrew Character, Silver Y (an immigrant and a common day-flier), Small Blood-vein, Square-spot Rustic, Vestal (another immigrant and a nice moth to find), Willow Beauty, Yellow Shell (27 spp).
The note ‘many’ simply records those which were particularly numerous.
It is extraordinary to think of the delicate Vestal migrating from Europe.

The moth trap was set up in the south-east corner of the woodland just off the path near the bird feeders. We ran the trap from 9.30pm to midnight.
The list of moths seen is: Brimstone, Common Carpet, Common Footman, Common Wainscot, Drinker, Flame, Jersey Tiger, Large Yellow Underwing, Lesser Broad-bordered Yellow Underwing, Lesser Yellow Underwing, Magpie, Oak/Northern Eggar (female), Orange Swift (male), Rosy Footman, Ruby Tiger (x7 in trap - more were seen but not trapped), Scorched Carpet, Shaded Broad-bar, Square-spot Rustic (18 spp.).
The ‘big moth’ of the night was Oak/Northern Eggar. The naming of this moth is complex and confusing. Northern Eggars are not confined to the north of Britain and for our purposes can be considered forms of the same species. There are differences in the larval life cycle related to what stage the larva over-winters and in colouration of the adult moth (the guide gives the darker colouration as Northern Eggar). But, whatever the name, it is a fine moth.
Oak/Northern Eggar (female)
Numbers of Ruby Tiger continue high. The larva of the Orange Swift lives underground on the roots of vegetation.

The moth trap was set up just off the path at the front of the orchard at the far end of the woodland. We ran the trap from 9.30 to midnight.
The list of moths seen is: Broad-bordered Yellow Underwing, Cloaked Minor (f. bicoloria), Clouded Border, Common Carpet, Common Footman (very numerous), Common Rustic, Common Wainscot (numerous), Drinker (several), Dusky Sallow, Early Thorn, Elephant Hawkmoth, Heart & Dart, Ingrailed Clay (prob.), Jersey Tiger, Large Yellow Underwing, Lesser Broad-bodied Yellow Underwing, Lesser Yellow Underwing, Mocha, Purple Bar, Rosy Footman, Ruby Tiger (very numerous - we may have seen approaching 50 - there were a dozen in the trap), Scorched Carpet, Sharp-angled Peacock, Small Fan-footed Wave, Willow Beauty (25 spp.).
The moth of the night was Ruby Tiger for sheer numbers, but probably the most interesting moth was a Mocha, classed as nationally scarce B, the third highest category of rarity. The Mocha is very distinctive and so the identification unambiguous. Although a small moth, it has exquisite markings, and its occurrence at the woodland is exactly right both in general and in habitat.

The moth trap was set up in the south-east corner of the woodland just off the path near the bird feeders. We ran the trap for about two hours from 9.30 to 11.30 pm.
Many species of moth came to the light, but it was surprising that few species were caught in the trap during this time. Those caught were 6 Drinkers and a Common Footman, but the full list of moths seen in the two hours of trapping was: Broad-bordered Yellow Underwing, Common Footman, Common Wainscot, Coronet, Drinker (x>9), Elephant Hawkmoth, Lappet, Oak Hooktip, Riband Wave, Rosy Footman, Satin Wave, Scorched Carpet, Sharp-angled Peacock and Swallow-tailed Moth.
We also saw micro-moths but did not record them. The Lappet proved to be a female and laid eggs overnight.
Our results can possibly be explained by the fact that moths fly at different times of the night as well as different times of the year, and we might have trapped more moths had we trapped for longer. Some of the more common moths we might have expected are perhaps late flyers at this time of year. It is also possible that our torches distracted the moths from the trap as we saw a good variety while we were at the woodland.
The number of Drinkers was a surprising result. Their larvae feed on tall, coarse grasses and rushes and they prefer damp areas so the woodland is presumably a good area for them.
Thanks to our award from the National Lottery Community Fund, we have been able to buy a moth trap so that we can discover which moths are visiting the Community Woodland and other areas of the village.
The group is very grateful to Stephen Locke for researching the most suitable moth trap for our needs and for obtaining a Skinner trap which is lightweight and portable and comes with a rechargeable lithium battery so that we can use it in places such as the woodland without a source of power. We set it up with a white backing sheet behind it as moths will come to rest on the sheet as well as fly into the trap and can be inspected if the trap is attended or if they are still resting there in the morning.

We are planning to trap at the Community Woodland on a regular basis and at different times in order to ascertain the full range of species throughout the year.
