A remarkable teratological case in Carabus violaceus L. (Coleoptera: Carabidae) from Poland

Background and purpose: Teratological cases in insects can be of different characteristic, quite often they are bifurcations, for example antennal segments or parts the legs. The aim this paper is to report a remarkable case leg duplication Carabus violaceus L. Materials methods: In context an interdisciplinary monitoring frame conservation project on European bison (Bison bonasus (L.)) Poland carabid fauna (Carabidae) areas grazed by species was studied using pitfall traps Pszczyna forest, located Silesia Province, south town Tychy. were inside mixed fresh coniferous with domination Scots pine (Pinus sylvestris L.). Results: Among carabids gathered teratological female specimen repeated anatomical duplications right front collected. Conclusions: incident bifurcation suggest genetic base teratology. An increased rate may have potential as bioindicator.
