The stictoleptura rubra ( Stictoleptura rubra , Syn. : Leptura rubra , Corymbia rubra , Aredolpona rubra ), and Red-necked goat or Common longhorn beetle , belongs to the family of longhorn beetles (Cerambycidae) and there to the subfamily of the narrow blocks (Lepturinae).
features
The beetles are ten to twenty millimeters long. There are strong differences between the sexes in terms of color and shape ( sexual dimorphism ). The red-necked buck is easy to confuse with representatives of similar species.
female
The elytra and the pronotum of the female are bright red-brown, the head is black. The antennae are medium-long and slightly serrated.
male
The coloring of the males varies. The elytra are yellow ocher and the pronotum is completely or partially black. The antennae are clearly sawn. The males are smaller and slimmer than the stockier females.
Way of life
Red-necked ibex feed on pollen and flower parts such as the stamens, pistils or petals of umbellifers or composites . The diurnal beetles fly from June to September. The animals can be found on meadows near the forest and in clearings on umbel and basket flowers. They can also be found on dead wood such as stumps of coniferous trees. The distribution area extends over large parts of Europe (in Great Britain the species is only represented locally), North Africa and Asia to Siberia . Red-necked ibex were introduced into North America and thus represent neozoa there . They are common both in the lowlands and in the mountains .
Larval development
The larvae of the red-necked buck xylobiont feed on dead coniferous wood, preferably on spruce and pine . The females lay their eggs on stumps and dead logs. The larvae develop in the wood in two years and pupate close to the edge of the wood. They can do a lot of damage to wooden houses.
