Some queries

The first is a macro that I really can't decide on.The photo is of the dead moth. Alive it looked more Pearly Underwing / Turnip shape and the hindwings looked right for Pearly Underwing.


I think the second is Dioryctria abietella but it was on the large size - about 18mm in length.


Finally the best I can come up with is Epinotia nisella but I am not sure. 10mm in length.


All from Monday night.

    Hi Andy, top one is Turnip for me, second one....I find the Dioryctrias very difficult so I'll pass (if I was forced I'd say abietella). Last one, the photo isn't very clear but I think it might be Ptycholomoides aeriferana. BW, Marc

    I agree with Marc, Andy. Turnip, Dioryctria abietella and Ptycholomoides aeriferanus. It is useful to try to get to grips with the Dioryctria species because, for me anyway, trapped specimens nearly always turn out to be female so can't be determined by dissection (only males can be separated that way). They generally fall into two pairs based on size, abietella (whose wing-length I think is understated in the field guide) and sylvestrella being the larger ones. With care, and on fresh specimens, they can be separated using the shape of the final black/white cross-line before the termen. I've had three of the four in my garden (never seen schuetzeella) but abietella is in my experience the most common.

    Many thanks. That is useful information as usual.
