FIRST FINDING IN SLOVENIA: not yet found in Slovenia in nature

PATHWAYS: transported with live plants and wood

POSSIBLE TO FIND: year-round

FLIGHT SEASON OF ADULTS: July-August

DESCRIPTION: Adults are shiny black beetles with a red pronotum, 20–40 mm long. On each side of pronotum there is a stout lateral spine. The antennae are as long as the body or longer. The larvae are elongate, 42–52 mm long and 10  mm in diameter, creamy white with three pairs of legs and feed on wood, in which they create oval boring tunnels with a diameter of 13 x 17-22 mm. Adults exit through oval emergence holes in the bark, which are 6–10 mm wide and 10–16 mm high. Damaged trees suf-fer dieback. They species overwinters as a larva in wood.

HABITAT: They are oligophagous on trees of the genus Prunus in variety of natural habitats, agricultural and ur-ban areas, plantations and tree nurseries. The larvae live in wood, and the adults in the canopy of trees, on bark of tree trunks and on branches.

STATUS: Found in several locations in Germany and Italy.

SIMILAR SPECIES: Musk beetle (Aromia moschata ambrosiaca) is similar in size and also has a red pronotum, but it has a metallic green body. It lives only on willows (Salix spp.). The larvae are similar to larvae of other cerambycid beetles.
