A fairly common species in the northern part of Belgium, elsewhere rather rare.
Native
Wingspan 16 - 24 mm. Forewings are reddish orange with silvery transverse lines. It shows a large and triangular pre-tornal marking, often forming a continuous band across the forewing. Almost never a white pattern in the external area of wing. Hind wings strikingly dark. Colors more intense, whites more washed out.
The eggs are yellowish-white when oviposited, changing in colour to greyish-yellow shortly after hatching and finally becoming orange-brown.
The adults fly from late May till the end of August.
The larva lives in a developing bud of Pinus sylvestris, Pinus nigra, Pinus contorta and Pinus sp. Young trees are favoured.
It inhabits pine forest, plantations, sandy areas with scattered pines and heathlands.
