Specimens in nature



The larva spins a loose web over the lower leaves of the foodplant, extending over several shoots. Under this web it spins a silken tube which extends downwards into moss and debris beneath the plant. The larva retreats into this tube when it is disturbed. It consumes the upper surface of the leaves, turning the leaves white. Larve can be found in April–June.
Pupation in a silken cocoon on the ground in the vicinity of the foodplant.
Especially males are active during daytime in sunshine. Females, which are slightly brachypterous, are not often flying.
