Eggs are oviposited at the base of Picea abies needles. The first instars mine during autumn in the base of the needles, later on they spin a narrow tube from where they further eat the contents of the needles. They also feed on the surface of a twig from a loosely spun gallery.
Pupation in May in a tough cocoon attached to a twig and some needles, close to the feeding place. This cocoon is well hidden because it is covered with particles of bark and frass.
The species hibernates as a larva.
The adults can easily be beaten from the trees and at night they come to light.
