Can anyone suggest which subfamily does this belong to? End of May, NE Hungary, brook. 1 cm. EDIT: The first photo shows another larva, a Chironomidae, the others show a Psychodid (?) pwalter attached the following image: [100.26Kb] Edited by pwalter on 13-01-2009 16:19

The other pictures are of a completely different larva - I'd say Psychodidae. Re-name the thread "psychodid? larva" to attract Phil - he may recognise the genus.

In (almost?) all species of Orthocladiinae there is a larger posterior and a smaller anterior eye. In other subfamilies the eyes are different: a single kidney-shaped eye=Tanypodinae, 2-3 smaller eyes, but about evenly large= Chironomini. In the latter family the eyes are orientated in a triangular (3-eyes) or in a vertical (2 eyes) plane. Tanytarsini have about the the same eyes as in Chironomini, but there is an antennal pedestal, which is diagnostic. There are off course many other features, but with some experience the subfamilies are easily seperated using the eyes and antenna only.
