Rhagium fasciculatum, a species occuring in Cuacasus and Transcaucasia, has been described from Transcaucasia by Franz Faldermann in 1837 [❖]. R. fasciculatum larvae develop under bark of various dead coniferous and deciduous trees (e.g. Fagus, Carpinus, Quercus, Alnus, Abies, Picea, Prunus). 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 [✧].
Body length: ♂♂ 11 - 19 mm / ♀♀ 13 - 22 mm Life cycle: 2 years Adults in: May - August Host plant: polyphagous on conifers and deciduous trees Distribution: Russia, Georgia, Armenia, Azerbaidjan, Turkey [▽]
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). The mounted male beetle was collected by M.Harnych in Timotesubani monastery (ტიმოთესუბანი) environs (1200 m a.s.l., Borjomi district, Samtskhe–Javakheti region, Georgia) on May 27-28, 2018.
