My cousin is a bug specialist at the LaCrosse WI DNR station.  I'll see if
she can shed any light.  In the meantime, DARE has (paraphasing):
1. fly of some genera of the family Corydalidae.  Cites not very localized.
2. = mayfly.  "Chiefly Gt Lakes, Upper MW"  incl a 1983 cite from Madison
WI: "Millions of smelly, sticky fish flies are making highways slick,
blacking out windows and piling  up a foot deep as the die in an annual
invasion of Mississippi River towns ... also know as mayflies and Mormon
3. = flesh fly.  cites from MI, MN, WA
4. A bluebottle fly.  cite from RI.
