Judolia sexmaculata, an European species of submontane and montane coniferous forests, has been described from Sweden as Leptura 6-maculata by Carl Linné in 1758 [✧]. J. sexmaculata larvae develop in the decaying wood of the roots of various trees (Picea is strongly preferred). Females lay eggs the base of the trunks or on exposed parts of the roots, young larvae feed subcortically and then enter the sapwood, where they also overwinter. Pupation in wood above soil level after the second overwintering at the beginning of summer. Life cycle 2 years. Adults, active from June to August, are diurnal and anthophilous [✳][❖].
