Five New Bess Beetles Discovered in Colombia, Bolivia, and Peru

Five New Bess Beetles Discovered in Colombia, Bolivia, and Peru

Beetles in the family Passalidae are one of the few groups of beetles that are subsocial — the adults actually care for their young and nest in decaying logs. Male and female adults pre-chew the wood and feed it to the larvae, which otherwise would not be able to digest it. They can even communicate audibly by rubbing their wings and their abdomens together — an act known as stridulation, which is often associated with crickets and other insects. Even the larvae are able to stridulate.
Five new passalid beetle species from South America were recently found and described in an article published in the Annals of the Entomological Society of America.
