Brachyta variabilis, a nominative subspecies occuring in Russia (North and Central European Territory, Far East, West and East Siberia) and Kazakhstan, has been described as Leptura variabilis from Siberia by Friedrich August Gebler in 1817 [▽]. Larvae of this remarkable beetle develop in the living roots of the milkweed Euphorbia pilosa, pupation occurs in pupal cells in the soil. Life cycle 3 years, some larvae pupate in late August-September after the second overwintering, but majority of the adult larvae pupate during spring (in May) after the third one. The adults, active from May to August, are diurnal and can be found on the host plants and flowers [✧].
