The situation in the Dioryctria genus is very confused. It consists of a number of very similar species in Europe and Northern America. It is still unclear how many species there are. In Britain three species definitely belong: D. abietella, D. mutatella and D. schuetzeella. The species shown here therefore is not a British species, but it is very similar to the British species indeed. The larvae of most species are associated with pines. The caterpillars are regularly found in the cones of pines and Norway Spruce. Even the wingspan of most species is about the same and runs from some 25 to some 30 mm. On the wing from mid-summer to late autumn.
