Hi


* locality - Silgueiros - Viseu - PORTUGAL
* date - 2007.06.15
* size - 7 mm (medium fly)
* habitat - openland, near river - near Quercus sp. above dry and burnt (?) Rubus sp.
* substrate - hovering with other acrocerid.


This fly was an amazing thing to see!!! It is breathtaking to see this fly at the first time. In dorsal view... we cannot see the head. :o It has a proboscis among the legs! All proboscis is yellow but at the extremity is a little dark. Legs are not totally yellow.

Third segment in antenna very short with apical hair , so Cyrtinae. Inside this we have 5 possible genus:
Cyrtus, Opsebius, Paracrocera, Acrocera y Ogcodes -- the last is totally black. The others have small proboscis, but Cyrtus has long proboscis as you can see. So probably Cyrtus. There is Cyrtus gibbus for Portugal, but the legs ARE NOT totally yellow. Neither can be C. pusillus because probosci is not totally black. My spanish friend Gallego helped me with biblio but we don?t have the descriptions for other possible species...

One thing is sure: this fly amazes me totally!! :D

EDIT ---> Title changed from "the most crazy fly I've seen so far! Acroceridae - Cyrtus sp. which one??" to "the most crazy fly I've seen so far! Acroceridae - Cyrtus gibbus"
