Blephariceridae larva was collected on stones in quick mountain river in Russia, Tuva (centre of Asia). I doubt what genus it may be. Body length 7 mm.

I've seen drawings of these things, but this is really weird! - from a different planet!

Dear Cranefly I have never seen this before and the family doesn't even occur here in The Netherlands. But I have looked at some drawings of Blephariceridae in Tsalolikhin (ed., 1999). key to freshwater invertebrates of Russia, part 4:diptera; plate 39-42; and your specimen looks quit like a species of the genus Agathon as pictured in plate 41:fig 7-11. The rows of small spinules on the head seems diagnostic. I will send you a copy of the Blephar...-part. Edited by atylotus on 21-03-2011 11:46 |

Many thanks, Atylotus! If it were not for simple not bufurcate (like in Agathon) dorsal lateral projections I would agree with you. Reallly ia looks like Agathon species from Tsalolikhin. Possibly I have some earlier age - the length of the largest larva I have is about 7 mm, the others are smaller. Agathon species are about 9-10 mm. But rows of spines and spots on head are very similar to Agathon spp. Let it be Agathon with some doubt. We can suppose that this character may appear in the last age. It was the first time when I saw this nice creature |

I had the same problem with Tripteroides larvae (Culicidae) - only one larva from the seria had branching seta, which allowed to determine it at last. Agathon species are about 9-10 mm. But rows of spines and spots on head are very similar to Agathon spp. Let it be Agathon with some doubt. We can suppose that this character may appear at the last age.

Key details of Agathon sp. are shown on this site, it might help too... http://www.dfg.ca...level1.asp Janet http://cubits.org... |

Many thanks . Looks similar. And dorsolateral projection simple there.

For those interested, Greg Courtney put together a number of Blephariceridae keys here: http://www.ent.ia...leph/keys/ From the Holarctic larval key I got the genus Asioreas (which is central Asian in origin), but a few of the couplets were difficult using these photos.... |
