Louse Fly

Maybe a louse fly?

Hi! Last night this strange little bug was crawling around in my hair. Kind of freaked me out. I crushed it while getting it out, but I could see what it looked like. Couldn’t identify it. This morning a similar one was crawling on my brother. He flicked it off into the kitchen sink and it drowned, but we fished it out and took pictures. I’m thinking maybe it’s a louse fly. THe whole creature is about 1/8” long. If I look VERY close I see tiny, tiny wings- no way they’d show up in pictures. Can you tell us about it and what we can do to keep them from crawling around on us?? Thanks!

Louse Fly

Hello Hannah,
Your suspicion that this is a Louse Fly is absolutely correct.  Considering that you are in northern Idaho, we suspect you might live near either a wooded area where there are deer or an agricultural area where there are sheep herds, two situations that would be conducive to supporting a large population of Louse Flies or Keds in the family Hippoboscidae.  According to BugGuide:  “Most are found on birds
” including the Pigeon Louse Fly.  The University of Florida website has an excellent web page on the Pigeon Louse Fly, and the Neotropical Deer Ked is also featured on a web page on the University of Florida Entomology website.
