Strobilomyia anthracina (Czerny, 1906)
cephalic skeleton (from Dušek)
(Generally one) egg is deposited in the lower part of a young cone. The larva bores a spiralling gallery around the axis of the cone, destroying cone scales and developing seeds. Infected cones are curved and strongly resinous. Out of an opening in the concave side oozes a mixture of frass and resin. Around August the larvae leave the cone and pupate in the litter below he tree.
