Distribution

The distribution ranges from western Europe and the British Isles east to the Ukraine, Georgia, Russia, Russian Far East and the Altai Mountains. In Fennoscandia it reaches Sápmi, it is still lacking on Iceland. The southern range includes Italy, the Balkans, Turkey, Asia Minor and the Caucasus. It is lacking, however, in the south and in the centre of Spain, in Portugal and the Mediterranean islands. In the Alps it rises up to the tree line.

Description

The wingspan is 16–19 millimetres (0.63–0.75 in). The ground colour of the forewings is light grey. There is a distinct, usually stretched discal spot and dark grey to brownish wavy crosslines, which continue on the rear wings. There are darker patches along the costal edge of the forewing, a paler white sub-marginal line and a chequered wing fringe. The hindwings are pale white with brown crosslines and a small black discal spot. Both forewings and hindwings are narrow. Darkened specimens with less distinctive pattern occur.[2]

The moths flies from April to July depending on the location.

The caterpillars feed on Norway spruce and also other Pinophyta species, such as fir, European larch and Juniperus communis.

gollark: I can probably type faster than I can... dictate at a computer, since while theoretically speech is faster than my typing, speech to text is inaccurate so I'd probably need to go back and revise things a lot.
gollark: Both equally unreadable, typing is far superior.
