Hello, I'm new to this forum and to ... diptera! The one I saw convinces me to look closer at these insects. I thought it could be Chaetorellia carthami; I received another suggestion: Orellia tussilaginis or "affiliated". Could you help me to identify it? Location: Tours (Center/West of France), near Loire river. Date: May 2005 Body size: about 8mm. Global view and details: Global:  Wing venation:  Thorax:  Head:  And first of all: congratulations for this very useful site!!  Matthieu |

As far as I can tell it is an Orellia, of which I only have data on O. falcata. These data fit the species here. However, there are two other species of which I do not know how they differ from O. falcata. The species you mention, Chaetorellia carthami, should have a pair of presutural dorsocentral setae, but these are absent. The species 'Orellia' tussilaginis is now placed in the genus Cerajocera. Orellia as restricted nowadays has the very long extension of the anal cell, as is present in this species. And thanks for the congratulations, though, being a member, you should congratulate yourself: It is the members who make the site what it is.

It's without a doubt Orellia falcata, the other two species, O. disctans and O. punctata differ from this species. The first lacks the black spots at the base of the scutellar and pre-sutural bristles, the second differs in having all bands on the wing connected. Nice pictures! Best wishes, John |
