Bionomics
Young larvae mine a number of leaves, entering though a round opening, mostly in the base of the leaf. Mined leaves are spun together. The frass is ejected, part of it is trapped in the spinning. Often the larvae can be seen outside the mine, in the spinning. Older larvae live free among spun needles. Hibernation in young larval stage in a mined needle.
The adults are active from dusk and later come to light.
