Hi bug people, I love this site! I am in north Dakota and with our weather getting colder our indoor fly population is finally declining. This year I’m noticing dead, dessicated flies on the walls, which isn’t too unusual, I realize they cling effortlessly with their clawed feet, but I’m seeing a white dust pattern beneath their little corpses. I’m would guess its wing scales shed during their distressing freezing death, but a professional opinion would mean a lot to me. Thanks for your time.
