About Archips crataegana (Hübner, 1796-1799)
Archips crataegana, commonly known as the brown oak tortrix, is a moth species belonging to the family Tortricidae. Its distribution spans from most of Europe eastward to Japan. This moth species exhibits clear sexual dimorphism in size: males have a wingspan of approximately 20 mm, while females have a wingspan of around 25 mm. The forewings of this moth have a sinuate termen. An irregular vertical costal fold runs from the wing base to two-thirds of the wing length, and is light brown or ochreous-brown. A transverse dorsal spot is located near the wing base. The anterior edge of the central fascia is angulated below the middle. The costal patch is extended as a streak to the termen above the tornus, and is dark ochreous-brown. The fascia becomes narrower and is sometimes completely absent towards the costa. The hindwings are grey; in females, the apex of the hindwing is sometimes yellowish. Julius von Kennel has published a full, detailed description of this species. Adult brown oak tortrix moths are active on the wing from June to August. The larvae feed on a wide range of deciduous tree species, including oaks (Quercus), elms (Ulmus), ashes (Fraxinus), and willows (Salix). Larvae feed inside a tightly rolled leaf. This species overwinters in the egg stage.
