dancing above margin of lake with piece of vegetation dangling - quite a few individuals doing the same thing. Probably very obvious to you guys but I have not seen this before. SW London

Ceratopogonidae. Never heared of this before. Certain it was piece of vegetation? Some midges also carry nematodes...

okay that might well be the answer, I wasn't aware they could carry such large parasites!

I would guess that the parasite is a horsehair worm (phylum Nematomorpha). As far as I know, they are the only known non-arthropod parasitoids. I haven't heard of them in Diptera before, so this is cool! In most zoology classes, what you learn about Nematomorphans is their killing behaviour: The adults mate in fresh water, and thus mature specimens routinely cause drowning in their hosts (e.g. http://www.youtube.com/watch?v=8ylDNMNNwaE). |

Racketman, I found this discovery of yours to be most interesting -- and passed on the info to Dr. Art Borkent, who is a (the!) world authority on Ceratopogonidae. He says: "...if this is from England, it is a female Mallochohelea nitida, with a ribbon of eggs dangling from her. This type of egg laying is present in a group of genera in the tribe Sphaeromiini. Good photo too! I'd be interested in getting a high resolution copy. Possible? Cheers. Art Dr. Art Borkent, Salmon Arm, British Columbia, V1E 2C2, Canada. email: aborkent@sunlite.ca website: http://www.inhs.illinois.edu/research/FLYTREE/Borkent.html" Thanks for any help on this, Eric |

Mainly you should make certain the size is less than 150000 bytes and there are no spaces in the file name.
