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.

Subspecies

Two subspecies are sometimes recognised:

Two former subspecies, namely Stictoleptura rubra dichroa (Blanchard, 1871) and Stictoleptura rubra succedanea (Lewis, 1873) are often treated as synonyms under Stictoleptura dichroa (Blanchard, 1871) in recent works. [1]

Description

Stictoleptura rubra can reach a length of 10–20 millimetres (0.39–0.79 in). [2] 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. [3]

Biology

Life cycle of this species lasts two - three years. Adults can be encountered from May to September, but mainly in July and August). They visit flowering plants for nectar and/or pollen, while larvae develop and feed within dead wood and tree stumps of coniferous trees ( Picea , Pinus , Abies , Larix ). [2] [4] To develop and reach maturity they need nutrients provided by fungi. [5] [6] Their gut contains cellulase-producing yeasts [7] to enable xylophagy, or wood-digestion.

Distribution

The species is found throughout the European mainland, Russia and North Africa. It can also be found in Turkey and Great Britain. [2] [8] [9]
