[Syrphidae] Re: larva

[Mutin Valeri]

Dear Nobby,
 
Probably, this larvae with anal papillae is a species from genus  Mesaxymyia (Axymyiidae). 
 
Best wishes,
Valery

>>hi Nobby

>>The larva seems to    be an eristaline but we need a picture of the whole larva, really. The "smaller kind of tubes" are the extruded anal "gills" that are usually held within the rectum, and are almost certainly involved in active ionic exchanges. If we could see them all, together with any lappets at the end of the body (base of the 'tail') and the anterior spiracles clearly (they are there but very out of focus) then we might stand a chance of identifying it.
