Default Dreamy Duskywing or Sleepy Duskywing?

I thought it was a Dreamy but it could be Sleepy . What do you think? It was on marigolds in a container with prairie dropseed.

I think I put this in the wrong place. but hope it gets seen.

So after a bit of reading I realized that it is late in the season for the duskywing to be either Dreamy or Sleepy (I like those names though). Here is one that flies in August. A hard butterfly to ID especially from a picture.

Quote:
The genus Erynnis (Duskywings) is probably the most difficult group of North American butterflies to identify in the field. However, the identity of a particular individual can often be narrowed to a few possibilities by noting the habitat and examining the range maps for each species (see INTERNET REFERENCES section below). A further critical comparison of an individual's key field marks to those in reliably identified images is often enough to arrive at a certain or near-certain ID; examination of the genitalia may be required in some cases but is usually not necessary when the preceding steps have been taken with due care.

Even side by side, I'm missing the difference. Can you see any?

I'm going to be talking to a class of high school seniors tomorrow. Their first project of the year is to put together an insect collection. One of my tips will be that the calendar is your friend. When you cannot tell if the bug is X or Y, find out which months X and Y can be found because that may provide your answer.
