Tha larva bores in a terminal bud from autumn till spring. Infested buds remain behind when the uninhabited ones begin to sprout. It needs several buds to complete its development. Pupation often between the needles in a gray cocoon or on the ground.
The adults are active in afternoon sunshine and later come infrequently to light.
Flight periods
The adults are on the wing from late May towards July.
Habitat
Frequenting silver fir plantations and mixed woodland.
