Pachyta quadrimaculata, a relatively common Palaearctic boreomontanne species with large area of occurence from Europe to North China, has been described from "Europa" as Leptura quadrimaculata by Carl Linné in 1758 [❖]. P. quadrimaculata larvae develop in the dead roots of coniferous trees (Picea, Pinus). Larvae first feed subcortically and then enter the sapwood, leaving the roots after the third overwintering. Pupation occurs in pupal cells in the soil during May-June, life cycle three years. Adults, active from June to August, are diurnal and anthophilous [✧][✳].
