I’m focusing on beetles this morning. More precisely, I’m sharing Horned Passalus Beetle photos that I took at Sequoyah National Wildlife Refuge in Oklahoma.

Adult Horned Passalus Beetles are shiny black with a series of grooves running the length of the wing covers and a short horn on the front of the head between the eyes.

Horned Passalus Beetles are large beetles, they are about an inch and a half long. They are also called bess beetles, Betsey Beetles and Patent-leather Beetles.

The Horned Passalus Beetles that I photographed at the refuge were found on fallen, decaying logs next to the roads. Wood is a significant part of their diet, and they are considered vitally beneficial because they aid in decomposition.

I enjoyed watching these large, shiny beetles through my viewfinder as they crawled around on the logs while I photographed them.

This last Horned Passalus Beetle photo was taken two days after the first three images on a brighter and sunnier morning. The refuge has a large number of fallen trees where these beetles can be found.

Info about Horned Passalus Beetles:

Horned Passalus Beetles are one of the few species of beetles that exhibit true social behavior. They live in cooperative family groups inside the decaying logs they inhabit. Adult beetles actively care for their offspring, which is a rare behavior in the insect world. They construct chambers and tunnels within the decaying wood to create a protected environment for their eggs and larvae. The family group includes adult beetles, larvae, and pupae, all living together and collaborating for survival.

Life is good.
