Hello. Am I correct in thinking that the attached image is of Rhagoletis meigenii? The image was taken in early July this year near a small pond in Worcestershire (VC 37).

Thanks.

No Rhagoletis.
The flagellomere 1 is rounded apically, and oviscape is intensively black and short, so it is Trypeta immaculata Mcq., a leaf miner on Taraxacum.
Also, R. meigenii has narrowe subbasal crossband, not fused to the short posterior patch (in T. immaculata forming a hook-like pattern)

eklans,

It is really a very difficult case without genitalia dissection.

I had to check myself twice.

That's true Val, but
...flagellomere 1 is rounded apically
is a very good hint. R. meigenii is quite common in my garden and I find it on Mahonia - and I've reworked my definition today TumbsUp

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
