It doesn?t like naphthalin.  lol It is a Hippoboscidae fly, BUT which one?  I hope you could tell more with these photos.The photos were taken under stereomicroscope by my friend. jorgemotalmeida attached the following image:  [182.51Kb] Edited by jorgemotalmeida on 09-06-2007 15:04 |

this fly has white color in ventral part of the legs except the last segments in the hind legs that are black; and, in all legs, it is black in dorsal part.

Tony Irwin wrote: 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 Edited by jorgemotalmeida on 09-06-2007 18:46 |

My mistake!  You are quite right, Jorge - I was mislead by the wings, which have not developed properly in this individual. I think this is an Ornithomyia species. I don't think we can take it much further with this photo. Have you any other shots? (preferably of a specimen with fully expanded wings!  )

I will ask my friend for more photos. But it could take a while to upload new photos. |

Please, try to dim the light somewhat. It is now impossible to tell whether the thorax is uniformely coloured or not. It should be in Ornithomyia, but should not in Hippobosca. BOth make some sense, given the locality. Theo |
