also on this sandy space in Fontainebleau forest, France, on april 11 2010, there was this little fly resting at the sun or waiting for something ?

Looks rather like Leucophora - an anthomyiid that specialises in parasitising mining bees by taking over their nests. It was probably waiting for a suitable host to appear.

I think the frontal vitta is to broad for a Leucophora.. Maybe a Botanophila, but not sure about it.. Do you have another photo..? Joke |

You amy be correct, Joke, but I thought that some female Leucophora had a broad frons (30% of head width). More photos would certainly help.

I think ......somewhere around Delia floralis / radicum /... Is it possible to make a crop of the area around the notopleuron setae? There should be some small hairs between them. Joke |

You did your best !! But difficult to say if there are hairs present....it seems there could be one below the shadow of the front neutopleural (and some females can have only one hair..), but is it convincing...no, i think just not sharp enough . Nevertheless i still think it is one of the Delia radicum/floralis/planipalpis group Pity...Joke

Many thanks Joke !! it's OK for me ! Identification from photographies is difficult enough, so getting a genus name and a group of few species is a good job !! on the contrary, it seems that Delia sp are plant pests and not parasites of wild bees as i previously thought ... thanks again ! |

it seems that Delia sp are plant pests and not parasites of wild bees as i previously thought Indeed many Delia sp. are pest. Delia radicum/floralis/planipalpis are often pest of all sorts of plants from the genus Brassica... Also many Anthomyiidae are leafminers (for instance..Pegomya, Chirosia) Just a very interesting group of flies...Anthomyiidae  Joke |
