Conoderinae: the Brazilian weevil who thinks He’s a fly!
Widespread in Curculionidae beetles, also known as weevils, mimicry offers astonishing models of study in these Species. Two Brazilian entomologists, Sergio A. Vanin (department of zoology-university of Sao Paulo) and Tadeu J. Guerra (department of Biology-federal University of Minas Gerais), have described in 2012 a new remarkable species of weevil that mimics Flies of the…
