Look like Eristalis tenax but I never saw those strips on thorax.

Looks like Helophilus pendulus. Should be in Syrphid Thread

rogerthomason,

I notice that in other photos of H.pendulud there is no thin median line on thorax. and second yellow line on abdomen seem to be split in the middle opposite to my complete line. Does it only inter sp. variation?

I'm no expert zcuc but I do know the difference between Eristalis and Helophilus, but as to the split in the median line on the thorax I have not seen that on any of the examples I have photographed. If you could move this ( or Paul or Chris) to the proper forum I'm sure you'll get a proper response. Regards Roger

Well, Maybe a Helophilus, but not one of the normal ones from the european continent. This could be H. parallelus, but I'm not sure!
Another possibility would be a Mesembrius sp., but that's not sure from the pictures either. Maybe I'll get back to after looking at some literature and stuff.
greetings

Hi all,
I'm promoting some of my unanswered threads since I can see that new people had joined the forum and maybe they also hold new knowledge and can help solving some of the ID questions.
