Retinia resinella

Pine resin-gall moth

Description

A small moth with 16-20 mm wingspan. In June and July, it flies in young pine stands, where the female lays eggs on the bottom side of buds. At first the larva feeds around the bud on the bark surface, later underneath. In the feeding spot flows out resin which forms a pea-sized lump by autumn. After overwintering the larva continues in feeding. The small lump grows reaching a size of a plum. The larva overwinters once more and pupates inside the resin lump. Before hatching, the cocoon moves out of the lump. It infests mostly 10-15-year-old pines. Although it is common, it does not have a tendency to an outbreak and damage, which it causes, is only limited.

Symptom
