I saw that you can tell these apart from photos.

I didn't know how, and I have this other one with no ID. Any ideas?

No, not really beyond local p
No, not really beyond local populations. You need to know the host plant and/or rear them to adults for a definitive ID.

How did you tell your two apart? The wide line vs. narrow line down the side? I'm just curious because Sweetgum is the host for both species, so the other one seems like it could be either species, and Winged Sumac isn't a host for either(?) so this one could be either? That made me think there was some way to tell from the images.

AFAIK Paectes pygmaea sticks to Sumac.

I see BugGuide lists Paectes pygmaea as Sweetgum and Paectes abrostolella as Sumac. Maybe the guide pages are wrong.
