New Moths - 23 June 2021

/

It was dry and still, but a bit cold overnight, so there weren’t too many moths in the trap this morning, but nonetheless three new species; a pug and two micros - all quite small and not very colourful.

The pug is a Currant Pug (Eupithecia assimilata), whose larval food-plant is (unsurprisingly) currant bushes. The large dark spots at the front of the wings and pale spots towards the trailing edge identify this species, which has 2 generations during the summer. Garden Pebble (Evergestis forficalis) is also double-brooded, favouring gardens and allotments where its caterpillars can be a pest on cruciferous plants (eg. cabbages). Finally the False Cacao Moth (Ephestia woodiella) has several similar relatives, but most of them are more likely to be found in food warehouses or your kitchen cupboards in the dried fruit, nuts or flour, than in the wild. Flying mostly in May-July, it seems to be becoming more common.

New Moths this Weekend

/

Apart from the pugs, carpets and some others I covered separately, there was a great selection of moths in and around the moth trap this weekend. There were plenty that I also caught last year, but I can’t show them all, so here are the new species that I didn’t already mention in other posts. Even with all the great materials around on the web, especially the “Flying tonight” sites for Norfolk and Hampshire it still takes quite a time to go through and identify everything, and I’ve still got a few caddis flies and other non-moths I need to look at.

More May Moths

/

The Buff Tip moth is one of my favourites, looking just like a snapped off birch twig, though it also frequents other species of deciduous tree. The Treble Lines moth is also one that I caught in June last year. It flies from May to July, its caterpillars eating plantain.

The two new species are the Marbled Minor, actually one of a trio of closely related species that feed on grasses, and the Rush Veneer, that also feeds on clover and grasses. The latter species is an immigrant from the continent that occurs in UK in large numbers sometimes, but usually later in the summer - this is quite an early record.

750 Species

/

Four new moths the other night brought my species tally up to 750. I’ve now seen 158 moths, 103 of which were added since I bought my moth trap around a year ago. We’re still waiting for some warmer evenings, but it does look like the weather is finally changing for the better.

April Moths

/

Despite the cold night-time temperatures there were a few moths about last night, not many in numbers but a few species including a few new ones. Pale Tussock was the most striking, also this is a quite early record for a species normally out in May-June. The Knot Grass moth is also more common later in the season, while the others are more typically spring species.

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.

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.

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.

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.

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.

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.

Mothing for the Weekend

/

My moth trap arrived, and even though the weather was not great - cold and quite windy - what the Hell, I had to give it a go. Not many species caught, but at least on the plus side I have to spend the whole day identifying moths! A single Heart & Club (Agrotis clavis) was the sole catch on Friday night, but it was a new species - one that is apparently very readily attracted to light. Saturday night was still and a little warmer after some rain, so I woke up to a moth trap with a dozen or so moths in it, including White and Buff Ermines, Setaceous Hebrew Character, an Uncertain, Willow Beauty, Riband Wave, Spectacle, Shoulder-striped Wainscot, Olive Pearl (Udea olivalis), Barred Marble (Celypha striana) and three more Heart & Club moths. Several of those caught were new species for my garden list, and I’m very happy with my new purchase.
