The Passalidae family is home to Bess Beetles, found in forests worldwide. With around 500 species, these beetles have a shimmering armor that ranges from dark brown to black; some have a reddish-brown hue. 

These robust creatures range in size from 0.8 to 1.7 inches and are a subtle yet beautiful addition to their woodland homes.

Their unique way of communication makes Bess Beetles stand out from other insects. They produce a symphony of sounds through the friction of their wings against their abdomen, known as "stridulation.”

These types of beetles display remarkable biparental care, a behavior uncommon in beetles. Both parents diligently feed their young pre-chewed wood.
