frass-covered silken tube
from the base the needles are completely mined out
mine
before the hibernation 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 external, mostly in the soil, sometimes in the tube (Freeman, 1967a; Hering, 1957a).
