Description of predatory behavior of the genus Lutosa walker, 1869 (Orthoptera: Anostostomatidae: Lutosinae) in Brazil

Abstract

They do not have a popular name, at least among non-native people. They are occasionally referred to as crickets, although they are not Grylloidea, but Stenopelmatoidea. Easily identifiable by the convex body in lateral view, shiny, glabrous integument, and with both apterous sexes. The anterior thigh has a lobe with spines. During the day they remain hidden under logs or stones, leaf litter, or in burrows dug by themselves. Buthidae are found throughout Brazil and makeup around 60% of national species. This family includes the genus Tityus Koch, 1966 (Scorpiones, Buthidae), the most dangerous. The species that exist in Brazil are divided into four families. This note reports for the first time the genus Lutosa Walker, 1869 in the Central-West Region, State of Goiás, Brazil, and the first report of the entire process of locust predation in the world.
