Crataerina pallida - a parasite of the swift (Apus apus)


hi Tony

thanks. But I must say that I was comparing with other photos in the net, and if these two links are right about Crataerina pallida...
http://img-x.foto...579020.jpg
and
http://aramel.fre...lida-5.jpg

it has some differences. For example, in the photos we can see that they have some constriction in thorax before the wings. In the fly of my friend there is no constriction. The proportion of the eyes with the head is much different.

Or the fly in those links have wrong ID?

Which are the definitive characters for this species? Thank you! I'm open to the discussion.


More one info: where the fly appeared there are two very common species: Passer domesticus and Hirundo rustica, AND also there are Tyto alba and Strix alluco
