A diary of my mothing activity covering highlights and photos from my moth trapping activities. Mainly Norfolk (UK), occasionally beyond. I may mention other wildlife sightings here, especially insects, but for birds see my birding diary.

New beetle and bugs make up for unremarkable moths

After a decent afternoon at the meadows on 28th May I set the light at home as usual and drew in a selection of moths over the night.  There was nothing very unexpected but the following were new for the year: Crescent Bell Epinotia bilunana, 2 Buff Ermines, Large Yellow Underwing, Mottled Rustic and Marbled White Spot.

The other moths were Diamond-back Plutella xylostella, Light Brown Apple-moth Epiphyas postvittana, 2 Garden Grass-veneers Chrysoteuchia culmella, Cream Wave, Silver-ground Carpet, 7 Green Carpets, Mottled Pug, Common Pug, Brimstone Moth, Scalloped Hazel, Poplar Hawk-moth, 2 Elephant Hawk-moths, Lesser Swallow Prominent, Coxcomb Prominent, 3 Pale Tussocks, 3 White Ermines, 2 Buff Ermines, 3 Heart and Darts, Flame Shoulder, 2 Common Wainscots, Rustic Shoulder-knot, Brown Rustic, 3 Treble Lines, Silver Y and 2 Spectacles.

This beetle on the ground near the trap proved to be Nebria brevicollis.  When keying it out on first attempt I misinterpreted the degree of swelling on the mandibles and the length of the palps so keying it to Leistus sp.  The Leistus key led me to Leistus rufomarginatus and the insect certainly looked a lot like the one I'd identified as that a while back (13th May).  But I noticed the size was slightly out and I decided to go back through the genus key and double check, at which point I realised it was Nebria not Leistus.  In hindsight I think I probably made the same mistake with the one on 13th May, and that that was probably Nebria brevicollis too, though I shan't record it as I no longer have the specimen to check.

I found a Treble Brown Spot in the hall the following day, a new one for the year, and a Diamond-back Plutella xylostella in the garden.

There was a good selection of other moths too: 7 Diamond-backs Plutella xylostella, Black-headed Conch Cochylis atricapitana, 3 Light Brown Apple-moths Epiphyas postvittana, 3 Common Marbles Celypha lacunana, 2 Rush Marbles Bactra lancealana, Triple-blotched Bell Notocelia trimaculana, Garden Grass-veneer Chrysoteuchia culmella, 4 Hook-streak Grass-veneers Crambus lathoniellus, 5 Small Magpies Anania hortulata, 2 Bee Moths Aphomia sociella, Pebble Hook-tip, Chinese Character, 2 Silver-ground Carpets, 2 Mottled Pugs, Currant Pug, 2 Common Pugs, White-pinion Spotted, Poplar Hawk-moth, 2 Pale Tussocks, 2 White Ermines, 4 Buff Ermines, 3 Heart and Darts, Shears, Lychnis, 4 Common Wainscots, 4 Treble Lines and Spectacle.

There was a single beetle in the trap, a new species for me Dasytes aeratus.

There was also a Hydropsyche pellucidula (caddisfly) and 2 Psallus sp. (mirid bugs) which at first I left unidentified.  Thanks to Tristan Bantock I have just accessed an excellent key that enables me to make more progress with these and I have been able to establish that they were different species, one Psallus varians and the other either Psallus perrisi or Psallus wagneri.  Both were females and the perrisi/wagneri pair need male genitalia to resolve to speices level (though I think perrisi is much more likely, and a male caught nearby a few days later was indeed this species).
