New Records of Anuran Predation by Giant Water Bugs of the Genus Lethocerus in Argentina (Hemiptera: Belostomatidae)

抄録

The aim of this paper is to report 10 predation events of anuran amphibians by giant water bugs of the genus Lethocerus in different localities in northeastern Argentina. With the exception of Scinax fuscovarius and Physalaemus biligonigerus, they are all new records of adult anurans being prey to these invertebrates. We conclude that this interaction is of extremely importance in the regulation of amphibian populations and should be studied in a thorough manner.
