Possible confusion species hovers at Ashwellthorpe
I was puzzled, when I reached home and viewed the hundreds of pix I took there on my monitor. There were several that didn't quite fit 'Ramsons'. I searched through Stubbs & Falk (the illustrated 'HoverBible') and Ball & Morris (the extremely useful, 'new' photographic guide), to no avail.
Emails to the County Recorder revealed the ID as female Cheilosia pagana. This is, according to those who know (not me), a member of a troublesome genus. Even more so, when this species is not illustrated in the former and shown with closed wings in the latter- and, moreover, has orange antennae, like the Ramsons !
Finally, I attach a mostly hairless (very worn) Bee-fly, which caused me more pondering; but, it is Bombylius major, our usual species.
