Erynnis iliaca?

Moved from Duskywings.

Sleepy Duskywing
This is clearly E. brizo. The lack of hyaline spots on the forewing, the locality and date all add up to that species. The Florida subspecies is E. brizo somnus if anyone is into subspecies.

even though the locale is slightly off from my field guide, this one looks more like E. icelus--my guide describes "two black chainlike bands enclosing gray scales", and E. brizo as "broad gray chainlike bands enclosing gray scales; no white spots". (Brock & Kaufman, p. 284)

from just a visual, this photo seems to match my picture of E. icelus with regard to those bands...

can you give me info to help me better distinguish which is which? (can you tell I'm mostly a moth girl?)

I don't have my references here right now to give more info on how to separate these two, but icelus does not occur in FL. So that makes the ID of this particular bug much easier. :-)

Sleepy vs Dreamy
Nina--separating icelus from brizo is easier in life than from photos but--icelus is consistently smaller than brizo, flies later and flies in different habitats. Brizo is in pine/oak barrens and oak scrub, whereas icelus is in more typically deciduous habitats, wet meadows and powerline cuts. Also, brizo looks "cleaner" whereas icelus has a chalky or powdery look on the forewings. Like so many other things, I can tell by looking butit is harder to explain. As Nick said, though, icelus is not in Florida as far as I know.

thanks a bunch!
that makes it much easier for me to figure out!

Moved from Skippers.
