I caught a mouse one night and found that there were four huge bumps on its back. I looked closer and saw what appeared to be botfly larvae in holes on each bump. I froze it and gave it to our local science teacher who dissected it with her class. Here’s a picture of what they dissected. Sure looks like a botfly to me!
I live in Fort Albany First Nation, Ontario, Canada, and I am surprised that there are botflys this far North! But is it really a botfly?
