HI
* locality - Silgueiros - Viseu - PORTUGAL
* date - 18.11.2006
* size - 6 mm (medium fly)
* habitat - open land
* substrate - granite with lichens (not so far grape fruits in decomposition)
I would say Muscidae fly. Not Sarcophagidae because the eyes are pale... (not strong red) stripes in torax... (not sure if Sarcophagidae have too), not have a metallic appearance (like in Calliphoridae)... still learning to distinguish correctly between these...
A very strange thing... the other eye - left - seems to begin emptying!!! is this usual?
I would say Musca domestica male... :|
Please provide me guidance in ID. I see a a gentle bend in vein M that is curved - and not abruptly bent.. and almost touching M4+M5 vein..
Seems the costa (vein costa - C vein) is broken in fore wing... at middle.

Musca autumnalis . Note the abdomen colour.
Costal vein not broken. Look at the right wing-I think what you saw as a costal break (just distal to the subcosta?) is slight damage.

hmm. you have reason. But the reddish colour is not so clear like in other photos. :)
Yes. that is costal break. ;) Thanks, Robert! :)

Reddish colour not just at base as in domestica so the abdomen is reddish with medial (centre-line) black stripe. Also
M.domestica is synanthropic. There are other species in the genus though.
