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.

Strawberry Tortrix and Fern Smut

I trapped two lifers on the night of Saturday 17th June. The first was clearly an Acleris laterana/comariana agg. but a very early date for laterana, and it was a bit on the small side.  I'd suspected comariana a year ago but the blighter escaped before I could confirm it, so I took great care not to let this one bolt for it!  One of the key differences in the genitalia are the size and arrangement of cornuti in the aedeagus (or in layman's terms, spiky bits in its willy!) but this one didn't have any cornuti (they sometimes leave them behind when mating).  The other features looked good but I wasn't 100% sure so sent a photo to Jon Clifton to check.  He confirmed what I thought - that it was a Strawberry Tortrix Acleris comariana.

The second was instantly recognisable as a Fern Smut Psychoides filicivora, but sadly it was also the only moth out of over 200 that didn't survive the night.  I started going through the trap at first light but by the time I reached it it was already dead in the bottom of an eggbox.  Still, a new moth for the house even if I am still yet to see one alive.  First recorded in Norfolk as recently as 2010 (Dersingham and Cromer) but there are now lots of records, mainly from the Broads.  Nevertheless despite Dick having recorded over 20 in five years at Dersingham, mine is only the second site in VC28 (west Norfolk) where it has been recorded.

One more moth was new for the garden: Hemlock Yellow Conch Aethes beatricella.

Another excellent moth which I saw for the first time last year was Satyr Pug.  This one was a bit fresher than last year's and perhaps should have been identified, or at least suspected, without dissection.  Sadly for would-be twitchers I didn't get round to looking at it that carefully until it was too late.
