Appearance
The eggs are oval and smooth, first white, then darken and before hatching the larvae become dark red. The larva is similar in shape and color to an adult insect, but has a shorter antennae, and smaller in size. Imagoes with an oval body, strongly flattened. The color is dark brown, similar to the color of pine bark. The head is massive, with short antennae. Proboscis filiform, several times longer than body. In the male, the front fore wings are sclerotized, the hind wings are completely reduced. Females come in two forms: long-winged and short-winged. A living insect emits the smell of cinnamon.
Nutrition
Adults and larvae live under the bark and feed on juice sucked from the bast and cambium of the tree, and in winter hide under the bark or in the garbage. Adult insects lay eggs from late April to early May on the bark of 5-30-year-old pines, and sometimes on young larch trees.
Economic value
In habitats are widespread, but they avoid light and therefore are relatively rare. In the case of mass infection of the tree, bark sections fall from the trunk and yellowing and decay of the needles are observed. Pine subcorn bugs do especially much harm in thickets. Natural enemies are camels.
