new marsh cosmet
Phragmites australis, de Lutte; herbarium Sjaak Koster
same mine, detail
Initially a corridor, but in the end half as wide as the blade. Widening of the mine is done by adding all tissue between two thick longitudinal veins. Most frass in the lowest part of the mine; part of it is ejected through a number of small holes. Both during hibernation as in the pupal stage the larva occupies the lowest part of the mine; the larva has spun a tube here into which it also retracts during feeing pauses (when lighted from behind, showing as as an opaque part of the mine). The pupa is laying head downwards, just above a preformed exit opening.
Larvae in August-April; hibernation in the mine (Hering, 1957a; Koster, 2002c).
