About the Red Pine Longhorn Beetle

Stictoleptura rubra, the red-brown longhorn beetle, is a species of beetle belonging to the family Cerambycidae. They visit flowering plants for nectar and pollen, while larvae develop and feed within dead wood and tree stumps of coniferous trees (Picea, Pinus, Abies, Larix). They have yeasts in their gut, enabling them to digest cellulose.

Stictoleptura rubra can reach a length of 10–20 millimetres (0.39–0.79 in). This species has an evident sexual dimorphism, with variations in color and shape. Elytra and pronotum of the females are uniformly reddish-brown or reddish-orange, while in males head and pronotum are black. Moreover the males have brown or pale ochre elytra and often they are smaller and narrower than the females.
