| Species: | strobilella |
| Authority: | (Linnaeus, 1758) |
Nationally scarce (Nb) in coniferous woodland and plantations throughout much of Britain. In Hampshire local amongst spruce in both vice-counties and, although not often seen, may be bred in abundance from fallen cones collected in early spring. Not recorded from the Isle of Wight to date. Wingspan 10-15 mm. Reminiscent of C. conicolana but differs in having golden yellow irroration on the distal three-quarters of the forewing, a transverse medio-dorsal stria extending to the costa and a weakly marked ocellus [Bradley]. Larva feeds within cones of Norway Spruce, causing sufficient damage to be a serious pest in some areas.
