Winter Moths

As it was a calm and dry night I was able to put out the moth trap for the first time in a while, and was happy to attract several moths, mostly around rather than in the trap. A couple of December Moths (Poecilocampa populi) and a Mottled Umber (Erannis defoliaria) were new ones for the garden, plus also there were a handful of Winter Moths (Operophtera brumata) and Light Brown Apple Moths (Epiphyas postvittana). In both the Winter Moth and the Mottled Umber the females are flightless, using pheromones to attract the winged males.

November Moth

Okay, it’s not quite November, but moth trapping this week, after a small gap, we had some new autumnal species.

First of the new species is the November Moth itself (Epirrita dilutata agg.), actually one of 3 very similar & closely-related species flying at this time of year, the others being the Pale November and Autumnal Moths, which in most cases require dissection to definitively identify. These moths fly now, laying eggs in the leaf buds of various deciduous trees, which duly hatch the next summer. The Beaded Chestnut (Agrochola lychnidis) also flies a single generation at this time of the year. The larvae live in rough grass, with the adults attracted to Ivy blossom. The second generation of the Grey Pine Carpet (Thera obeliscata) is another September-October moth.

The other moths caught included Turnip Moth (Agrotis segetum), a Silver Y Moth (Autographa gamma) and a couple of Light Brown Apple Moths (Epiphyas postvittana). The latter species is an accidental introduction all the way from Australia, which since arriving in Cornwall in 1930’s has expanded its range to become a common species in much of UK.

700 Species

Getting a moth trap has been a game-changer in terms of adding new species to my list this summer - also a lot of fun. I brought up my 700th species in some style with a bevy of beautiful moths this morning after a perfect warm & still September night.

#696 Dusky Thorn (Ennomos fuscantaria)

#697 Straw Dot (Rivula sericealis)

#698 Large Ranunculus (Polymixis flavicincta)

#699 The Mallow (Larentia clavaria)

#700 Light Emerald (Campaea margaritata)

Swallow Tail and Gold Triangle

There are some more moths from earlier in the week, pushing my garden list closer to 700 species. The Swallow-tailed Moth (Ourapteryx sambucaria) was a particularly beautiful one; also quite a late record for this species, which is commoner in July.

The Gold Triangle moth (Hypsopygia costalis) has two postures, this one with its wings splayed out and tail in the air and a more normal moth-like v-shape. It’s larvae live in dried vegetation, like hay stacks or my neighbour’s thatched roof. The other two moths are also typical for the season; the Pale Mottled Willow’s (Paradrina clavipalpis) larvae live in cereal grain, while those of the Rosy Rustic’s (Hydraecia micacea) live underground mostly in the roots of plants of the dock family.

Clifden Nonpareil

This super-impressive Clifden Nonpareil or Blue Underwing moth was attracted to my moth trap last night. These moths were extinct in UK and only reported as migrants, but the last few years have been turning up more often and it appears may well have re-established themselves. The warmer climate may have contributed to their return. They typically fly in September, their larvae preferring aspen and poplar trees. With a wing-span of 75-95 mm it’s a pretty big moth, the blue underwing (just visible on this photo) is believed to play a role in surprising predators so it can get away. Once the “Holy Grail” for moth enthusiasts, they may be getting commoner, but this is still a rather special creature to find in my own garden!

#689 Clifden Nonpareil - Catocala fraxini

Grey Dagger Caterpillar

My sharp-eyed youngest son spotted this colourful caterpillar in the corkscrew willow tree. It is the caterpillar of the Grey Dagger moth (Acronicta psi, #611). I’ve caught adults in the moth trap, which are virtually indistinguishable from the rarer Dark Dagger moth, but the caterpillars of the two species are quite different. Grey Dagger caterpillars are found on a variety of deciduous trees, such as Oak, Birch, Hawthorn, Elm and seemingly Willow too.

September Moths

After a bit of a break during the holidays, it was good to get my moth trap back out and see what was about. Among the Large Yellow Underwings there were a few new species. This Black Rustic and a couple of prettily veined Lunar Underwings were my favourites. I nearly missed the Small Dusty Wave altogether as it is more or less perfectly camouflaged against egg box grey.

#683 Black Rustic - Aporophyla nigra

#682 Square-spot Rustic - Xestia xanthographa

#685 Lunar Underwing - Omphaloscelis lunosa

#688 Pale Mottled Willow - Caradrina clavipalpis

#684 Garden Rose - Tortrix Acleris variegana

#92 Small Dusty Wave - Idaea seriata

Moth Bonanza

It’s taken me a few days to identify all the moths I caught on Friday night, with 15 new species added to the list. There were many moths in the trap and even more all around on the house wall and surrounding plants. Some of the highlights below. Without the moth trap you only see a fraction of what is out there.

#666 Magpie moth - Abraxas grossulariata

#236 Garden Carpet - Xanthorhoe fluctuata

#667 Lesser Swallow Prominent - Pheosia gnoma

#674 Carcina quercana

#245 Yellow-tail - Euproctis similis

#675 Water Veneer - Acentria ephemerella

#546 Ruby Tiger Moth - Phragmatobia fuliginosa

#673 Iron Prominent - Notodonta dromedarius

#671 Nutmeg - Anarta trifolii

#664 Lesser BB Yellow Underwing - Noctua janthe

#672 Straw Underwing - Thalpophila matura

#676 The Coronet - Craniophora ligustri

Moth Trapping in Winchcombe

For a change last night I was trapping in my Dad’s garden in Winchcombe. He’s always reminiscing about how many more insects there were back in the old days, and he’s for sure correct. Even so it was great to catch a pretty decent selection of moths, several that i didn’t yet catch at my place. I took some photos of a few of the more colourful ones and ones I didn’t recognise, including a Marbled Green (Nyctobrya muralis) which seems pretty unusual this far from the coast. A rather impressive Sexton Beetle had dropped into the trap; this is a carrion beetle that searches out dead small animals and raises its larvae in a burrow under the corpse.

Gold Spot (Plusia festucae)

Maiden's Blush (Cyclophora punctaria)

Poplar Hawk-moth - Laothoe populi (#663)

Among a whole bunch of moths, which are going to take me a while to sort out, this amazing Poplar Hawk-moth (Laothoe populi). The main flying season is May-July, so this one is a little late, or maybe it’s from a second generation. This hawk-moth is one of the commonest in UK, but very spectacular.

Five New Moths

Monday night was my best night’s trapping for quite some time, including five new species. The Brimstone Moth was not new, but the light drew in several of these and I didn’t get a photo the previous time I recorded them. Scalloped Oak, Single-dotted Wave, Shuttle-shaped Dart, Straw Underwing and Turnip Moth were all new, reflecting a shift in the season and new generations of these moths appearing. I caught several Shuttle-shape Darts, Straw Underwings and also Riband Waves, plus individuals of several other species.

#657 Scalloped Oak (Crocallis elinguaria)

#606 Brimstone Moth (Opisthograptis luteolata)

#658 Single-dotted Wave (Idaea dimidiata)

#659 Shuttle-shaped Dart (Agrotis puta)

#660 Straw Underwing (Thalpophila matura)

#661 Turnip Moth (Agrotis segetum)

A Pair of Beauties

Here’s a nice pair of “beautiful” micro moths. On the left a Marbled Beauty (Bryophila domestica, #652), caught last week in the moth trap. This species is camouflaged to hide up on a lichen covered wall;its caterpillars are lichenivores, feeding on lichens, usually on rocks. On the right a Beautiful Plume Moth (Amblyptilia acanthadactyla, #222) that appeared from some garden waste I was clearing out.

Lesser Waterboatman (Sigara lateralis, #646)

Another first, this time my first Waterboatmen, with a dozen or more caught in the moth trap. Looking like something from Roswell, these bugs (not beetles) are strong fliers and often attracted to light at night. There are several similar species, but based on pattern and leg/foot colour, I believe this one is Sigara lateralis. I released them in my small pond - may they be happy there!

The moth is a rather faded Double Square Spot, the first of these I’ve caught. Apart from a coupe of Large Yellow Underwings and an unidentified brown Caddisfly there wasn’t much else in the trap.

Moths in the Garden

After a bit of a break from putting out the moth trap due to recent windy and wet weather, it went out at the weekend. This Common Rustic (Mesapamea secalis, #642) was the only new species, but the catch included a splendid pair of Buff Ermine moths (Spilosoma lutea). Another new moth is this leaf mine from the apple tree, which is from the tiny Apple Leaf Miner moth ( Lyonetia clerkella, #643).

Scarlet Tigers

There are many Scarlet Tiger moths (Callimorpha dominula) around at the moment, flying around in the late afternoon and evening, or resting up during the day. They are so numerous here, that it’s surprising to see that their distribution in UK is rather restricted to the south and west of the country. The caterpillars like Comfrey, but I also find them on the Green Alkanet in the garden.

There were 8 or so Scarlet Tigers around the moth trap the other morning, plus a few other species like this Clouded Silver (Lomographa temerata) and a bunch of “micro” moths, including an Ermine (Yponomeuta sp. several species are too similar to ID in the field), Grey Tortrix (Cnephasia sp. ditto), Bramble Shoot Moth (Notocelia uddmanniana) and Codling Moth (Cydia pomonella). Codling Moth is a nuisance in orchards, as its larvae tunnel into the core of the apple, leaving a “maggoty apple” with a dirty brown tunnel through the fruit.

Moth Trap Update

Caught a few new moths earlier in the week. The Buff Tip (Phalera bucephala) is not new, but I like them a lot, so I thought I’d include this photo of one trying hard to be a birch twig in the morning sun. The Common Footman (Eilema lurideola) with its yellow edges was new, as was my third type of wainscot moth, the Smoky Wainscot (Mythimna impura). Finally, all the Riband Waves (Idaea aversata) I have seen or caught so until now have been mostly pale, so it was nice to catch this one that actually had a dark “riband” across the wings.

#625 Smoky Wainscot (Mythimna impura)

#629 Common Footman (Eilema lurideola)

#132 Riband Wave (Idaea aversata)

Trio of New Moths

No rain last night, so the moth trap was out and catching a fair number of moths, the Heart & Dart being the most numerous, with a couple each of Vine’s Rustic and Uncertain moths. With these there were three new species: a Bright-line Brown-eye (Lacanobia oleracea), a twig-like Flame moth ( Axylia putris) and a Barred Straw (Gandaritis pyraliata). The Barred Straw is an unusual looking moth as it rests with its fore-wings completely covering its hind-wings, and in this case fluttered off before (unfortunately) I could get a better photo.

#619 Bright-line Brown-eye - Lacanobia oleracea

#620 Flame - Axylia putris

#621 Barred Straw - Gandaritis pyraliata

Weekend Finds

This weekend there were a few new bugs about. This rather fine leaf mine on a Nasturtium leaf is from the larva of a fly, probably Pea Leaf-miner, Chromatomyia horticola (#616), though there is another species with an identical mine. Chromatomyia horticola mines leaves of different plants, which include Sow Thistle and Garden Peas, both of which I find in the garden with similar narrow white mines.

The smart-looking black & grey fly appears to be Anthomyia procellaris (#617), due to the placement of the block spots. It is not an uncommon fly, often found sunbathing - in this case on my potato plants. Its larval life-cycle is not really known.

The moth trap was fairly quiet on Sunday morning, with this rather burgundy-tinted Middle-barred Minor (Oligia fasciuncula, #615) the only new species caught. On Saturday night I noted several insects flying around the light turned which I thought were stripey micro moths, but it turns out hey were my fist species of caddisfly, the aptly named Long-horned Caddisfly (Mystacides longicornis, #618). Caddisflies are usually associated with water, where their larvae live in a case made from bits of sand and gravel. My garden is quite far from any stream, so either these insects roam further than you might expect, or maybe they are from one of my small garden ponds.

More Marvelous Moths

After a couple of fruitful trapping evenings I had a bit of a backlog of photos and a few identification challenges I was still working on. I’m impressed how many moths I’ve caught, and the variety of species - I had no idea there were so many around. I particularly love the birch twig imitating Bull Tip and the pattern on the Grey Dagger, neither of which I’ve ever seen before. As the weather has turned a little wet and it looks like it will be windier too I’ll give it a rest until the weekend and see if there’s anything else around I should take notice of.

600 Species - Small Elephant Hawk Moth

Moth trapping is getting quite addictive, and I’m very happy to reach 600 species in style with this gorgeous Small Elephant Hawk-moth, found in the trap this morning. I’m still working on identifying some other of last night’s moths - but this ID was pretty straightforward. Nice!
