A rare and widespread species in Belgium.
The larva feeds internally in the cones of conifers. The trees must be sufficiently mature as to produce large numbers of cones. Hibernates as a pupa in a flimsy cocoon among fallen conifer needles or other plant debris on the ground.
The adults come to light.
The adults fly in one generation a year: onwards from mid May towards mid July.
The larva feeds on conifers like Abies procera, Picea abies and Picea sitchensis.
