Crambid Snout Moth - Udea profundalis

Crambid Snout Moth - Udea profundalis
Lacey (near Olympia), Thurston County, Washington, USA

Pretty sure this is Udea, but I can't see how to tell the difference between Celery Leaftier and the False Celery Moth (which is probably one reason it's called that, huh?). A little help moth folks? :)

Moved from Moths.

Most likely
Udea profundalis based on geographic range. Check out Info section on BG for Udea profundalis. Notes that U. profundalis is found mainly west of the Rockies and U. rubigalis mainly east of the Rockies, but they're very similar.

 
Ok, I'm going with U. profund
Ok, I'm going with U. profundalis, but I had a previously identified moth here:

Should I change the ID on that one? Also, while I understand your comment about U. rubigalis being mainly east of the Rockies, if you look at the "Data" section for U. rubigalis, it shows the Celery Leaftiers as being nationwide. Should a moth expert go in there and clean up some (all?) of those western entries?

 
Yes,
... I agree, it's not very clear. I changed my original photos from rubigalis to profundalis, but it's murky - guess one of the editors should make a call.

Just checked in Powell & Opler, Moths of Western North America. They say the two species are closely related, but U. profundalis is larger - forewing 8.5-12 mm vs 6.5-10 mm for U. rubigalis, (although there's quite an overlap there!) Hindwing primarily white in profundalis, whereas it is patterned with dull rust in rubigalis. Also:"Older Pacific Coast specimens (before 1950) were called U. rubigalis which ranges trasncontinentally, whereas later ones have been identified as U. profundalis. Probably the name rather than the species U. rubigalis has been replaced." Still a bit vague.

Dick Wilson has had a specimen ID'd as U. profundalis under the BOLD project. I also started sending moths into them for DNA analysis this year. Have sent in three or four of these guys. Will let you know when I hear back, but it might be a while.

 
Just to let you know
that I sent 4 specimens into BOLD and all came back as Udea profundalis.
