July 04, 2006. Size around 3mm. Could this one be the same as the fly in a thread by Vadet: http://www.diptera.info/forum/viewthread.php?forum_id=5&thread_id=36&pid=102#post_102 Dmitry Gavryushin attached the following image:  [110.15Kb] |

This is Chamaemyia and looks very like C. fasciata |

This is what I knwo of Chamaemyia with black abdominal bands: * Third antennal segment darkened apically, tarsi completely yellow, as a whole more greyish dusted. -> fasciata * Third antennal segment yellow, last tarsal segment darkened, more yellowish grey dusted. -> elegans I am not quite sure where that leaves us, with apparently all yallow antennae, all yellow tarsi and greyish dusted body. Score 2-1 for fasciata, I guess. Paul - - - - Paul Beuk on https://diptera.info |

specimens i have named as fasciata have entirely yellow 1st flagellomere and look just like the above photo. Is there an error in Collin's 1966 key? he says ?More yellowish-grey species with third antennal joint distinctly darkened towards tip?? elegans Pnz. Whitish-grey species with third antennal joint almost entirely yellow?. fasciata Lw.? |

Well, the family Chamaemyiidae is notoriously difficult. Recent work on the European fauna has only been done by Tanasiichuk and I think I took this from an older work by him. In a more recent work on the Diptera of the Russian Far East (2001) there is one species with banded abdomen and it is refered to as: Ch. fasciata Lw. (elegans Tanas., non Panzer) That might mean that Collin (and you) are right and that I followed a wrong interpretation by Tanasiichuk. I will see if I can find out more.
