flies

[Ankit Gupta]

i have seen many insects , mostly house flies , rubbing their hands or legs (whatever it is) but why do they do so ?

They're plotting evil schemes.

 

Honestly though, they're cleaning. They first rub their front legs (I guess you could equate it to arms) over their bodies to gather any particles that might be stuck there. The dust sticks to their legs, and they then rub it off their legs, which is what we see when they're rubbing their hands together.
