Hi, The star of this photo was the bee Heriades truncorum, but it was not alone on the Tanacetum vulgare flowerheads. When taking a closer look at the photos, I detected a small fly with beautiful green eyes. Is it possible to name it? I have no closer and better pics... Location is the Baltic Island of Usedom, close to the bay water, in August. Many thanks, Sundew |

Tephritidae. Maybe Ensina sonchi...

LOOOL  Incredibly! And you have Helophilus - Syrphidae and Sepsidae fly under the Ensina.

So what is the fourth fly on the picture at the upper right corner?

the wasp can be Braconidae. At least, belongs to the Ichneumonoidea.  to put a name in the fourth fly is nearly impossible, I think. |

The tephritid, of course, is Ensina sonchi L.; another similar fly could be Eurasimona (=Urophora) stigma (Loew), but the latter one has widely black scutellum w/ yellow tip; this one has yellow scutellum, like in a typical Ensina; August is also a proper time for the latter.

Hey, it's very kind of you to take interest in all members of the Tanacetum party. The biggest one is a male of Helophilus trivittatus, the black bee I told you, then there is a braconid wasp, already spoken of in a previous thread, and Ensina you kindly identified. Moreover, there is a loving couple of Dioxyna bidentis in the upper left, a miniature Hymenoptera in the middle, and two likewise tiny flies that I suppose to be Scatopsids. The fly Gabor inquired about possibly belongs to my favourite family Anthomyiidae, so I didn't dare to ask (and the anal vein is not recognizable ) Flowering Composites and Umbellifers always host a big variety of visitors, and it is very paying to spend some time there watching, especially for a beginner. I am longing for the next summer!!! Best wishes to all, Sundew Edited by Sundew on 02-03-2008 12:04 |

in the small image seems to be a wasp (maybe Pteromalidae??). The fourth fly with these photos can be Anthomyiidae?? The others are Nematocera.

Sundew: what you called "loving couple of Dioxyna bidentis" could be in that area also Campiglossa producta Lw. or C. difficilis Hend. as well, both more or less common there in Baltix.

I met these tephritids on nearly every Tanacetum or Tripleurospermum flowerhead, and I think they belonged all to the same species. There was a previous thread they took part in (http://www.dipter...d_id=10729), and Dioxyna was not a matter of doubt then. I have no better pic of the couple above but add another one on Tripleurospermum. Are there any animals among all these that you would put into Campiglossa, or are the pics so poor that you cannot decide, Valery? (The mosquito, by the way, is a male of Ochlerotatus caspius, kindly identified by Tony Irwin.) Thanks for all your efforts, Sundew PS. Jorge, of course you are right - no scatopsids in this case, legs too long and wing venation different. I should have looked closer... Edited by Sundew on 02-03-2008 12:02 |

Sundew: thanks for the additional photo: here, the fly on the right has more rufous and smokey tinge, like in a typical D. bidentis. The left seems to have yellow femora, also like in D. bidentis, though its wing pattern looks much darker on the black background. In fact, C. producta differs not only in black femora and dark brown, contrasting wing pattern, but also by essential genitalic characters. So, this couple IS Dioxyna bidentis. Val |
