Limb amputation by male Neotropical longhorn beetles during competition for females

Abstract

The biology and mating behaviour of the spectacularly large and brightly coloured Neotropical longhorn beetle Schwarzerion holochlorum Bates 1872 (Coleoptera: Cerambycidae) is largely unknown. For the first time I report and photographically document violent male-male competitions for females involving frequent amputations of competitors' legs and antennae.
