Pupation and hatching under the bark during end of summer/autumn before the second overwintering. Life-cycle 2 years. Adults, active from May to August, are diurnal and often anthophilous [✧].

The living specimen was collected and photographed by P.Jelínek in Norio (ნორიო) environs (Kvemo Kartli region, Georgia) in May 2016. The depicted mounted beetle was collected by M.Rejze in Cankurtaran Gecidi E Hopa (NE Turkey).
