Clover Looper - Caenurgina crassiuscula

Clover Looper - Caenurgina crassiuscula
DuPage County, Illinois, USA
June 19, 2005

Moved from Forage Looper.

Shouldn't this be moved
to C. crassiuscula? I would do it myself but I don't know the protocol.

I believe this is actually a C.crassiuscula. I've always understood the difference between crassiuscula and erechtea to be in the border of the forewing marking, as I have shown in this illustration of two BugGuide images:

The C.erechtea has a curved border, while the C.crassiuscula has a straight border of the marking. There is also a slight difference in hindwing marking. If I'm wrong on this, I'll gladly concede, but this is the distinction I've always been familiar with between these two species. :) *Edit* - I should also note that Covell states the dark bands across the forewing do not touch the inner margin in erechtea, while they do touch the inner margin in crassiuscula (as on the specimen in your photo).
