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. jorgemotalmeida attached the following image:  [183.34Kb] Edited by jorgemotalmeida on 21-11-2006 15:27 |

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. Edited by Robert Nash on 21-11-2006 15:57 |

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. Robert |
