Ocorrência e sazonalidade de Omorgus (Omorgus) suberosus (Fabr.) (Trogidae: Coleoptera) em esterco de aves poedeiras, em Monte Mor, SP

Abstract

Trogidae is a cosmopolitan family whose species have mainly necrophagous habits. They are among the last groups of the sucession of insects that invade carcasses, but they have also been recorded feeding on bat guano in caves, locust eggs, fly maggots and unusual itens, such as old carpet and felt-hat. From July 1991 to September 1993 the trogid beetle Omorgus (Omorgus) suberosus (Fabr.) (Coleoptera:Trogidae) were abundantly collected in poultry manure in Monte Mor, SP, with pitfall-traps. The seasonal distribution showed the unimodal pattern with peaks into spring and summer.
