This little fellow measured only 1.6 mm. What a round head, and what a very distinct neck. I know the picture is not the best; hard to see the rear of the wings, for example. What family? Resting on a squash leaf, open area near woodlands, West Virginia USA, 5 August 2006. Thanks for any help you can provide!

Hello, Stephen! I may be wrong, but I think that critter does not belong into Diptera but into Hymenoptera. Some kind of parasitic wasp (?). Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |

I am thinking of Diapriidae.

Tiny size, paddle-shaped fringed wings with very reduced venation, jizz suggest Mymaridae a family erected by our (Ireland) countryman Alexander Henry Haliday . as a possibility (no time to check now) but Paul may well be right. Robert In the meantime take a look at http://hymenoptera.tamu.edu/keys/?taxcpl=cpl&taxcpl_id=1 which keys some reduced venation Hymenoptera |

The antennal implants are too close together for Mymaridae and the shape of the antennal segments is also off.

Juergen, Jan, Paul, Robert, I am impressed, you not only do Diptera but Hymenoptera as well. Thanks for setting me straight on this one. While I can no longer say this is the tiniest Dipteran I have ever photographed, it is nevertheless the tiniest wasp. Thanks again!
