Podapion gallicola
Pine Gall Weevil
Podapion gallicola is a weevil that induces galls on pine branches. It has a three-year life cycle on its host tree, with adults emerging in June and ovipositing through August. Larvae feed gregariously on cambium and xylem tissue, triggering gall formation during their second instar. The species is known from Michigan and eastern Canada.
