Description

External images For terms see Morphology of Diptera

Wing length 6-7·25 mm. Antennae reddish. In front view the distance between the eyes at most equal to the width of an eye. Wings blackish-tinged. Female thorax with purplish reflections. The male genitalia are figured by Maibach, A. & Goeldlin de Tiefenau (1994).[2] [3] [4] [5][6] The larva is illustrated by Rotheray (1993).[7]

Distribution

Palaearctic. Ranges from Fennoscandia South to Iberia and the Mediterranean basin, including North Africa. From Ireland Eastwards through of Europe into European parts of Russia, Ukraine and the Caucasus mountains.[8][9]

Habitat.Ireland.

Biology

Habitat:Wetland and deciduous forest, woodland streams and ponds including Salix carr. Flowers visited include white umbellifers, Cornus, Filipendula, Galium, Sambucus, Senecio jacobaea. The flight period is June to September ( May in southern Europe). The larvae live in pond mud containing debris of fallen twigs and branches.[10] [11]

gollark: In one study, there were flies put in some conditions where they couldn't have many children, and instead of evolving to have fewer, they just cannibalized each other's young.
gollark: What? I don't think evolution generally selects for group benefits.
gollark: According to the osmarks.tk styropyro discord political compass interactive data visualization™, C4 has an Arbitrary Cultural Score of -6.5.
gollark: How would *that* work? Don't you have a lockscreen?
gollark: I think I'm somewhat more likely to post weirder things late at night, but that's because I end up getting tired and my brain works "glitchily" then.
