Dahlica triquetrella - female

Dahlica triquetrella - Female
Tracy Hall, Norwich, Windsor County, Vermont, USA
May 24, 2011
This is apparently an adult female Dahlica triquetrella, perched next to her pupal skin, which is projecting from her larval case/cocoon. Two perplexing things about this--one, she appears to be a hollow shell: if you look closely you can see three irregular holes of different sizes, which don't really look like exit holes of a parasitoid to me; and two, she is much smaller than her pupal skin, as is the case in this example:

That is very
odd. I would guess she was parasitized, but who knows. I swore I saw a male moth a nondescript moth, at a pupae last year. It flew off before a picture. But when I first went searching, some expert on these in Europe (Netherlands maybe?) he told me NO WAY. That this is strictly parthenogenetic. Maybe there really are some males after all- which might account for the large pupae? And your right, the pupal skin seems out of synch size wise. But how would the wingless female get there? Hum. Really interesting. Seems that we'll have to raise some and watch a bit closer for emergence in action to just ferret out how it works??? Thanks though Charley!! Great stuff.
