Lifecycle NotesThe larva creates a distinctive, spherical or ovoid resin gall on pine shoots, where it feeds and develops over two years. Pupation occurs within the gall, and the adult moth emerges in late spring/early summer.
Identification TipsThe most reliable identification is by the distinctive resin gall formed on pine shoots, which is typically spherical or ovoid, covered in hardened resin, and often has a dead shoot or bud protruding from its center.
Description
The adult moth is small, with mottled grey-brown forewings often featuring darker bands and a reddish-brown patch, providing excellent camouflage against pine bark.
