The largest family was Curculionidae, followed by Scarabaeidae, Carabidae, Coccinellidae, Silphidae, Cerambycidae, Dermestidae, Staphylinidae, Tenebrionidae and Trogidae. Weevils (Curculionoidea) also, represented the greatest proportion in terms of number of individuals. During the present study captured beetles from all three localities were compared and Shannon indices were calculated as a measure of diversity within the habitat. The Shannon diversity index has been found maximum (1.035) in Trebujeni, moderate (1.017) in Ivancea and low (0.936) in Lozova.
