I have great trouble in identifying "blow-flies" and "house-flies", even in making the distinction between families. With this one (which I suppose it is a sarcophagidae), the Diptera gallery couldn't help. Are the flies in both pictures of the same species (in one of them the anus cells are red) ? They are both pretty large flies about 15 mm long. Thanks, Joaquim Gaspar Lisboa Alvesgaspar attached the following image:  [184.47Kb] Edited by Alvesgaspar on 10-09-2007 17:53 |

remember: usually red traffic eyes drive us to Sarcophagidae with this kind of jizz. It has checkered abdomen, stripes on thorax (specially on scutum - anterior part of abdomen). usually the calliphoridae flies have metallic colours comparing with Sarcophagidae, for example. There are exceptions, though. this is a Sarcophaga sp. Impossible to day more. Genitalia should BE examined.  Just there are some sarcophagids that are (usually) more easy to ID like the Miltogramminae (subfamily inside Sarcophagidae family)flies.  |

S. carnaria has too traffic red eyes and red genitalia.. But it is not known for Portugal. I doubt that really with photos we can be sure about species specially with a Sarcophagidae on our monitor. |

There are several Sarcophagini species with red genitalia, by the way, carnaria not among them. Some of the most common are Ravinia striata (or pernix, it keeps changing its name for some reason) and several Helicophagella, I think.This one seems neither. THere are more, though... Sarcophagini can (virtually) never be identified from picture. No matter how good the pic is. Theo |
