Hello, this morning 21th july 2011 at an abandoned field at Girona province, NE Spain...on Euphorbia flowers it seemed to be a couple in one plant and another couple in another... Is that common? And if the the male is the bigger it seems to me unusual among the diptera. How is possible to know the sex in this group (it seems easier among Syrphidae). Well, and also would like how to separate E. crassipennis from E. oblonga, if possible.

This one is a collage of the bigger one (male?), now is the smaller one (female?)

Ectophasia sp. yes ... but the last ones in the last photo are Gymnosoma sp.

Uuups! So I will update the second picture... which detail is necessary to know the Ectophasia species? And what sex are they?
(I asked for the Robert Belshaw�s key at the R Entomological Society, but they did'nt answer)

The second Ectophasia (well, now I'm not sure is the same individual as the one above)

Hello, I was checking this post again, and didn't get clear. Would you mind to tell me if we call the pics:
1 2
3 4
And from the last ones
5 6
Which anyone of them look like Ectophasia and which of them like Gymnosoma? (all the images I see from Gymnosoma they lack spots on wings)

Thanks in advance,

Rafael

They are all Ectophasia ... Gymnosoma don't have mottled wings :)
