Studies have found this species can consume over 100 cereal aphids in a single night, making it one of the most valuable natural enemies in wheat fields.
Flattened Giant Millipede Beetle
A large, flattened bess beetle with a shiny black body and a small horn on the head. Adults and larvae live together in rotting logs in a subsocial arrangement. Adults produce sounds by rubbing their hindwings against the abdomen.
