Subfamily: Phycitinae

Taxon: Dioryctria schuetzeella

Authority: Fuchs, 1899

Account: Nationally scarce (Nb) in pine woodland in south-eastern England. Restricted to the New Forest, although there have been no reports in recent years. Scattered sightings elsewhere, including from Freshwater in 1985. Some of these, if not all, may not stand up to critical examination. Wingspan 26-28 mm. The genus Dioryctria contains four closely related species in Britain, which require close examination to separate: D. schuetzeella is the smallest and more contrasting of the four, with fascia and discal spot broader and whiter. Larva feeds on Norway Spruce, living between needles spun together with silk.
