Thanks Jorge & Paul. I must show more respect for muscids, I thought they were all non-descript grey flies. |

Have a look in the Gallery and you will see some nice examples not fitting your previous concept of Muscidae.

Looked at Muscid page - some attractive flies; I'm always learning. Surely not another "damned anthomyiid" in another "damned genus"  To photograph a hind leg I would have to remove one, relax it, and flatten it. Could you tell me what you are looking for  |

The choise is between Pegomya, Thricops, Phaonia... Well: 1. Is vien R4+5 setulose basally? 2. How many pd on t3? 3. Is there small v seta on very base of hind basytarsus? 4. How long vein A? 5. Is scutellum fine hairy ventrally? Nikita Vikhrev - Zool Museum of Moscow University |

Thanks, I wish I hadn't asked Will check out all 5, once I work out what a pd on t3 is. Tabanids are so easy  |

pd = posterodorsal, meaning posterodorsal setae.

Nice Job, Tony 5. If 2 strong setae on middle of your diagram is pd - than correct answer is 2pd + 2ad (last (3-d) pd - (pre)apical). Anyway your diagram is very usefull - it shows "Angthomyiidae type" on t3 Along with other points it seems to my that Kahis was right - Anthomyiidae, probably Pegomya. Kahis?

Nikita OK, 2pd and 2ad, didn't realize there was a 3-d pd: Saw Paul's ref. to pd, thought I understood it and then forgot all about the ad's With all my fancy photo equipment thought that I should be able to get a decent photo; seems OK but not entirely satisfied. Thank you all for your comments. |

The correct spelling would be basitarsus, often also named metatarsus but officially named as first tarsomere.
