can't find this on any of the sites
No interactions present.
Certainly Meliscaeva auricollis. Whether it is maculicornis, I am not sure. The ones which I have, have much smaller spots, especially on tergite 2.

Thanks Moremouth and Ophrys,
today I almost bought the Stubbs book on hoverflies as I'm finding more species not on the websites. Is it the right book to get, or is there something else extant that you might recommend?
latest pics and diptera videos
Yes...it is the one to get...a fantastic book. There is also a Wildguide to hoverflies coming out at some point, which would also be worth getting.
Stubbs to be recommended Join the BENHS British Entomological and Natural History Society and they have an offer

great! It's on its way. Thanks too for the link
I cannot not agree with Moremouth, it's not just a match visually and for the time of year, I just can't see anything else in that species that appears close, and if there's agreement that it's M. auricollis..
I'm trying to track down the wildguide to hoverflies mentioned, has it actually been published yet and if so, where can it be found? And crucially, does it absorb up-to-date research on x.pedissequum, which I now need? Stubbs is writing ten years ago, anticipating the species split and forthcoming guidance..
No. It keeps getting pushed back. If Roger Morris drops by, he could update you. I have the Xanthogramma details somewhere...I'll have a look when I am at home.
cheers very much. The birders mentioned it this morning when I pointed out how close we were to my sighting. A heady few days. Mine seems to have a spot, a dash and two tiny dots which might be pollen, on the side of the thorax. Must check xantho spot again, then I'll put the bird pics up.
By the way, 'primary projection' must mean how far the wings feathers extend, ie, how long they are?
Slightly confused by all the references above (!), but I can answer primary projection...it is the length by which the primary feathers extend beyond the tertials, when the wing is at rest.
thanks. excuse the somewhat telescoped references, people like myself don't usually encounter so many staggering species, so close together, in such a short time, and with a sense that it's to be presented to a certain standard. Ispot burnout looms, I fear.
Stubbs says that the 3 pedissequum species are to be defined by the number of spots on the thorax sides, and so I'm glad I bothered to take the extra shot when it crawled under a leaf, which appears to show that area.
I need the bird info to present the bird that was just across the road
Sorry, I am probably missing something, but where is this Xanthogramma you are referring to? Can you link a reference to it?
If you really want to get into such subtleties as the Xanthogramma pedissequum group, you should consider joining Dipterists Forum. The Spring Bulletin gave Alan Stubbs' pragmatic key to the three species. Essentially, points to look for relate to...
Colour of membrane betweeen tergites and sternites
% of microtrichia on 2nd basal cell
Number of spots on pleura
Colour of wing apex
Colour of stigma
Shape of tergite markings
Colour of lower squama marginal hair
If you have the specimen, you could possibly get there; if not, forget it! dives and stackelbergi are the possible extra species referred to.
I assumed it was of little interest due to very low id difficulty, here it is:
thanks for the pointers. I might well join the forum
(actually was hoping for some feedback on your h.polyglotta id but can't now wait)
