Wild Indigo

Based on field marks-- Dark median patch and light area beyond cell, as well as date (late summer) and location--Minnesota--I would I.D. this as Wild Indigo. Persius is not recorded from Minnesota and is much grayer with longish white hairs on the wings. In any event, I think it is better to put these shots with the duskywings that they almost surely are, rather than to lump then all under Duskywings and say they cannot be identified positively from photos. This is what a male Wild Indigo Duskywing looks like for sure, even if there is an outside chance it is something else.

Consensus

It looks like you, Chad and I all agree, so I'm going to go ahead and move this since we have a consensus.

Duskywing - Probably male Juvenal's

For Minnesota, and the noted markings, this appears most likely to be a male Juvenal's Duskywing. Erynnis juvenalis. Glassberg's Butterflies through Binoculars, Plate 50 no.3.

are you sure?

I looked up some flight period information and it appears that most Juvenal's have a single flight period that peaks in July while Wild Indigo Duskywing has flights until October in the southern portion of its range.

Also, the pale windows on the forewing seem small and inconspicuous and I can't seem to find a picture of a Juvenal's that fits that characteristic.

Any additional thoughts?

Erynnis

You are probably correct. It does appear to be a species of the persius complex. My thoughts are that it is a 2nd brood male Erynnis baptisiae. But technically, the only way of being certain in the persius complex species is by examining genitalia.
