Species Account

Similar species: The four Dioryctria species in Britain, are difficult to tell apart. In particular, D. abietella with similarly pine-feeding 1454b Dioryctria sylvestrella and 1455 Dioryctria simplicella.

Sutton & Beaumont, 1989: Records under this name include D. mutatella (Fuchs), formerly regarded as a form of abietella but now considered to be distinct. These old records are quite widely distributed in vice-counties 62 to 64 but only one has presently been confirmed as referring to the present species. Further work is required to establish the relative frequencies of these two moths in Yorkshire.

Beaumont, 2002: In 1989 most records were unconfirmed, the moth is now recorded in small numbers from widely scattered localities in vice-counties 61 to 64. There is, as yet, no perceptible difference in the distribution of this and the next species within the County.
