Hylobius abietis
Large pine weevil
The adult is dark brown with pale little spots on elytra. It is 10 to 14 mm long. The head is elongated into a noticeable nose with antennae on its end. The female lays eggs onto roots of fresh pine and spruce stumps. The larva is whitish, limbless, slightly arched, 12–23 mm long. It pupates in the bark. Feeding under the stump bark is not harmful; to the contrary, it speeds up their decay. The maturation feeding of sexually immature adults is dangerous on conifer seedlings, especially pines. Feeding of adults on trunks is square. The adult beetle feeds on the bark just above the ground, in deep, funnel-like holes up to sapwood, which causes intense resin production. In case of severe attack, it damages the entire little trunk and the seedling dies.
