Thread subject: Diptera.info :: Psychodidae larva?

Posted by pwalter on 12-01-2009 15:34

Hi, I just wanted to show how interesting this larva looks like - especially the tail. 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 (?)

The first picture is a chironomid larva, probably Orthocladinae. :)
The other pictures are of a completely different larva :o - I'd say Psychodidae. Re-name the thread "psychodid? larva" to attract Phil - he may recognise the genus.

Thanks tony, I attached a wrong photo (first pic), somewhere I have a photo of the larva that is seen on the microscope-photos. But I thougt that one also for Chironomidae:)

I think this is a Pericoma, but I'd like to see a more complete view if possible.

Thank You, I'll make one at the weekend. I'm excited about what it is:)

Ulomyia or Pneumia is as close as I can get.

The Chironomidae is definately an Orthocladiinae. One of the easy to see features are the eyes. 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.
