In Hampshire and on the Isle of Wight common where there is pine on heaths and plantations throughout the county, but distinctly uncommon on the Island. Wingspan 24-30 mm. The genus Dioryctria contains four closely related species in Britain, which require close examination to separate: D. simplicella is usually more uniformly grey in appearance than the other three species, exhibiting a reduction in contrast between the ground colour of the forewing and the paler cross-lines and discal spot. Larva feeds within young shoots of Scots Pine, Corsican Pine and Maritime Pine.
