Distribution


It is found in Kazakhstan, Mongolia, China, Russia, Korea and Japan.



Description


The wingspan is 60–102 mm. The colour ranges from light yellowish brown or light grey to dark brown or almost black. The forewings are crossed by two dark stripes and there is a white spot situated at the centre of the forewing.



Life cycle


The length of the life cycle varies from two to four calendar years depending on population density. The larvae of the males have five to nine instars, while those of the females have six to ten. Adults are on wing from the end of June to the beginning of August. The larvae (second to third instars and fifth to sixth instars) overwinter under the forest litter. Pupation takes place from mid-June to late July.[2] There are cycles of slow build up of population over several years, reaching a peak (outbreak) followed by a population collapse.[3]



Host plants and damage


The larvae feed on Larix, Picea and Pinus species. It is the major defoliator of coniferous forests in Asian Russia.
