Maple Callus Borer - I think! - Synanthedon acerni
just north of the St Paul city line in Falcon Heights, Ramsey County, Minnesota, USA

Came to UV lights. I think this is the right ID. It matches the description on the info page. Also, the info page says it's the only eastern Clearwing species that's attracted to lights. First for Minnesota.
