Strobilomyia infrequens (Ackland, 1965)

on Larix

parasite

The larva feeds on the seeds in the cone. The general image of the infestation strongly resembles the one of Strobilomyia laricicola. However, the egg generally is deposited well hidden on a scale in the top of the cone, and there is no phase in the larval life when a lengthwise tunnel is bored in the axis of the cone.
