gall

In fact not a gall: infested shoots can only be distinguished from normal ones by a sprig of dead leaves at the top. The larva lives, above the dead growing point, in a tube formed by the leaf sheaths of the upper two internodes. Pupation internal, univoltine. Both larva and pupa are distinguished from the other Lipara‘s because their front and rear ends are black.

hostplants

Poaceae, monophagous

Phragmites australis.

larve

egg, larval stages and puparium are meticulously described by Grochowska (2006a).
