Main: (Tortricidae / Tortricinae)
49.059 [B&F: 1033] Green Oak Tortrix (Tortrix viridana) Linnaeus, 1758

 

Notes: Common in oak woodland, woodland, parks, gardens and areas with scattered trees throughout much of the British Isles. In Hampshire and on the Isle of Wight formerly abundant in oak woods, though prone to annual fluctuations. At times, larvae would reach pest proportions and form the staple diet for insectivorous birds and their young, but this phenomenon is rarely noted nowadays. Wingspan 17-24 mm. This species is unique amongst the British Tortricids in having a light green, almost unicolorous forewing [Bradley]. Larva feeds on Oak and deciduous trees, living within a spun or rolled leaf, causing sufficient damage to be a serious pest in some areas, over-wintering as an egg.
