Scarabaeoidea (Insecta: Coleoptera) Of The Kaliningrad Region (Russia): The Commented Actual Checklist, Assessment Of Rarity And Notes To Regional Protection Author Alekseev, Vitalii I. text Acta Biologica Universitatis Daugavpiliensis 2018 2018-12-31 18 2 111 152 journal article 298071 10.5281/zenodo.10979877 13070b4b-afe1-4eae-8c82-2afda9e0bfe5 1407-8953 10979877 (5) A. bimaculatus (Laxman, 1770) Bercio & Folwaczny 1979. Kaliningrad Region : Gur. (Königsberg), Gus. (Gumbinnen). Comments: The beetles and larvae feed on horse dung. The species range formerly included Estonia ( Silfverberg 2010 ), Latvia ( Telnov 2004 ), Belarus (Alexandovitch & Pisanenko 1991) and southern regions of Central and Eastern Europe. The evident decline of populations and decrease of distributional range in the XX century in the northern parts of areal is recognized ( Nikitsky 2016 ); the species is included in the Russian Red Data Book ( Nikitsky 2001a ) and is listed in the Red Data Book of the Kaliningrad Region ( Dedkov & Grishanov 2010 ) as the regionally extinct during last 50 years species. The beetle has the “possible extinct” status in Poland too ( Pawłowski et al. 2002 ). The actual presence of the species in the regional fauna needs confirmation and the field work in eastern parts of the Kaliningrad Region should definitely clarify the question.
