Moths in Late October Snow

 
I have an enduring memory of moths flying under a street light in a late October snowfall. The scene has stuck in my head for over ten years. It must have been a pretty unique day weather-wise (in other words a fairly standard weather day in Minnesota); unseasonable warmth that ended with a night time snowfall
 
I'm not sure what species of moth they were (this was well before my moth phase). But the following three species are adapted to colder weather, and are active in the fall:
 
Winter Moth - Erannis tiliaria
Fall Cankerworm Moth - Alsophila pometaria
Bruce Spanworm - Operophtera bruceata
(Don't bring me down)
