Eggs are deposited on the underside of a needle.
After 10–15 days the larva emerges. The young larva mines the needles of Larix during the first two instars.
Later on, it constructs a small case from a part of a needle in which it hibernates. After winter it continues feeding in spring. Larvae are fully fed around the end of May.
Pupation happens on a needle, bud or on a small twig.
Very often, the adults are to be find on the lower branches of Larix.
