the tiny emergence openings
orange-brown larvae live communally in galleries filled with a brown mycelium in the leaf sheaths. Pupation in the gall, in a silken cocoon. After emergence of the adult midges, the exuvia remain protruding from the exit openings.
according to Skuhravá & Skuhravý (2004b) the name by Coutin & Faivre-Amiot, 1981 is a nomen nudum, and the correct species name is Lasioptera donacis Coutin, 2001. However, here the Fauna Europaea (2016) is followed.
Thomas & Goolsby present a very detailed description of the larvae. The observation by Skuhravá & Skuhravý (2004b) that the larvae would live in old galleries of Cerodontha phragmitophila is not confirmed by them. However, they write that groups of eggs are deposited in “preexisting holes”.
