I'm not sure it is Diptera, I,m not sure it is even Insecta, may be mollusca or leech. First time I see such regular stracture. Moscow region, 15 july, small pond.

Hi Nikita Chironomidae usually lay their eggs in jelly, and they often arrange them in a spiral or circle within the mass. These are probably what yours are. Tony Tony ---------- Tony Irwin |

Thank you Tony. It is a difficult case. In addition to this site I showed photo to several Russian entomologist. There are two possibility so far: 1. Yours, Chironomidae. 2. Another one, Trichoptera. Photo is from last year, 15-th of July, so in two weeks this eggs have to appear again in my pond. This time I'll try to do my best to rear it and find the answer.

Have you found some more and reared them yet? Maybe less time in Thailand and more time in Moscow, and you would have done this!

Having looked at Walter's post again (http://www.dipter...d_id=19364) - I'm sure yours are chironomid. The narrow shape of the egg is typical of a nematoceran, and they certainly look just like the eggs of chironomids I was studying 30 years ago.

Hello, I thought that Chironomidae laid eggs directly in water. On our French forum, we had a series of pictures (http://www.galerie-insecte.org/galerie/wikig.php?Ponte) that we tentatively identified as Chironomidae. Pierre Duhem |

1. So Chironomidae. Not too poetic answer  2. Thank you Tony and Pierre 3. Have you reared them? Maybe less time in Thailand and more time in Moscow eggs of chironomids I was studying 30 years ago Tony, you forgot during this 30 years, that rearing under -10C is somewhat problematic Nikita Nikita Vikhrev - Zool Museum of Moscow University |
