Tortrix viridana

Green oak roller

Description

Green oak roller – as the name suggests – has grass-green forewings and grey hindwings. This combination is relatively unusual among the European moths. The forewings wingspan is approximately 13 mm. The female lays eggs into tree crowns always in pairs. The egg overwinters. The larva lives in a bud in spring, later it spuns several leaves together and pupates inside. It is greyish green with a shiny dark head. Moths fly in June. It is especially common in warm steppe localities. Several other species from the family Tortricidae feed on oak, including Acleris literana, A. quercinana, Tortricodes alternella, Ancylis mitterbacheriana, Pammene  plendidulana and Strophedra nitidana. Moths Tortrix viridana, Lymantria dispar, Malacosoma neustria and Euproctis chrysorrhoea are the most important cork oak defoliators in the western Mediterranean.
