Bionomics

The larva mines a few needles completely out, then hibernates in a needle. After hibernation another number of needles is completely mined out from their base. The mined needles are held together by a frass-incrusted silken tube. Most frass in the tube, a small fraction in the mines. The larva mines all its life.
Pupation in a white cocoon in the larval tube or amongst leaf-litter on the ground.
They are active in afternoon sunshine and at dusk and later come to light.
