there are other families where we can see flies moving their wings: Sepsidae, Ulidiidae (like this one), Tephritidae, Chloropidae, and more :P

I wish to know why these flies usually moves their wings in this way.. I don?t know the reason. Perhaps anyone could provide an explanation.

It's a desperate call for attention! Either they try to attract a mate, or warn rivals to stay away, or both :)

there is a small problem with this possibility. I have spotted many ALONE flies doing that. There are no flies around when some flies do that. :S If the things were simple... :)

In case of Sepsis, as far as I understand it send signals
to another male - "I'm bigger"
to another sex - "I'm ready for mating"
to SAcathophaga - "I'm poisonous!"
to Dipterologist - "I'm Sepsis sp.!"
