Aberystwyth Micros

I also had an excellent catch last night - over 100 moths with a 15W Actinic+Skinner trap, including Pinion-streaked Snout, Mottled Rustic, Anania lancealis, Eucosma cana, Cnephasia stephensiana, Borkhausenia fuscescens, Oegoconia quadripuncta, and this micro which I can't figure out:
 Also found this attractive Lozotaeniodes formosanus while checking lights around the university buildings:


  1. Hi Simon, can I ask what parameters you used to decide you had stephensiana and also what made you decide you had Oegoconia quadripuncta rather than deauratella? Up until very recently no Oegoconia had been recorded in the county. As for your unknown image, do you have any better shots to show the colour more clearly? I can't make out what it is.

  2. Hi Simon, have you hung on to the moths? Particularly the Oegoconia, (you never know it may be one of the others, not the one you had before). The Grey tortrix, (these usually can't be done without dissection), and the unidentified one.
    It's a good haul! Have you got that daughter of yours out finding these?

  3. I must admit that I did have some help yesterday morning, although my helper was more interested in the "elephant".
    I had assumed that the Oegoconia was the same as before, and the Grey Tortrix looked like the pictures in the book, so I was happy to assume.
    Sorry, I didn't keep them, but I've put some more pictures at
    The unidentified one was rather small, FW about 7-8 mm; most noticeable was the white stripe along the lower side and the dots at its end; the light has given it a rather warm glow.
    Thanks for your help.

  4. Keep Oegoconia's in future Simon and also any Cnephasia's. Whilst you can determine stephensiana often, just because it's bigger than the others, and often darker, it is still wise to get it chopped. That goes for all Cnephasia's.The unknown does look like a Phycitodes of some sort, but it's too small for the common one. Beyond that I'd have to chop it. If you hand over kept one's to Ina, she'll pass them on to me to id for you.
