I guess 牛盳 is gadfly or horsefly?

 It's the most painful sting on your list. The fly has a sissor like part in its mouth, and literally cuts open you skin to get blood.

Only the female flies in summer mating seasons need to get blood.

I'm surprised that you had quite a lot of experiences working in rice paddies.
