Thank you Nikita, I'm glad  that my fly found a name, but I would very happy  to know why (why Midaea instead of Phaonia).Where must we search the differences between this two genera ? Eric Steckx |

Eric, generally Mydaea has setae on radial node of wing (both on dorsal and ventral sides) and has not pd on t3. We can't see these characters on your image, alas. But scutellum helps in this case - some Phaonias have black abdomen and scutellum partly yellow, some Phaonias - all yellow scutellum and partly yellow abdomen. Your fly has enterly yellow scutellum + enterly dark abdomen. Nikita Edited by Nikita Vikhrev on 06-11-2008 22:50 Nikita Vikhrev - Zool Museum of Moscow University |
