Mating occurs through the season, either on flowers or on trunks, and females oviposit into bark or in cracks on dead wood of coniferous trees (Picea, Pinus, Abies, Larix), mostly on standing trunks and stumps but also on fallen timber and logs. Larvae develop over two or three years, they feed deep into the sapwood (xylem), producing longitudinal galleries, avoiding decaying areas, and pupate during May and June in a cell beneath the bark or near the surface of the xylem.
Dydis 12-18 mm. Kūnas juodas, antsparniai patinų rudai geltoni, patelių – raudoni. Patelių priešnugarėlė raudona, o patinų juoda. Būdingas lytinis dimorfizmas. Patinai mažesni už pateles. Vabalai aptinkami ant įvairių žiedų, ypač gausūs spygliuočių miškuose. Lietuvoje dažna rūšis.
