Horned Passalus

Horned Passalus

Odontotaenius disjunctus

A species of Odontotaenius, Also known as Bess Beetle, Peg Beetle, Jerusalem beetle, Betsy bug

The horned Passalus (Odontotaenius disjunctus) is a beetle that has the power to pull things up to fifty times its own weight. Given that it is an insect that can pull its own weight, a brood care mindset is an excellent option. Parents and older offspring dig a "parental tunnel" where younger offspring tend to live in for an entire year.

Life Cycle of Horned Passalus
Egg The eggs of horned Passalus are small and typically laid in concealed locations. At this stage, they show no resemblance to the adult horned Passalus, being mostly immobile and vulnerable.
Larva After hatching, the larva of horned Passalus grows significantly, molting several times. It is worm-like, has a distinct head, and primarily consumes food for growth.
Pupal The horned Passalus enters the pupal stage enclosed in a protective casing. Within, it undergoes a radical transformation, reorganizing its body structures into adult form.
Adult Emerging from the pupa, the adult horned Passalus's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

Habitat Preferences of Horned Passalus Through Different Life Stages
Adult horned Passalus are typically found in hardwood forests, often under logs or in decaying wood where they create tunnels and chambers. Larvae develop within the rotting logs their parents inhabit, thriving in this nutrient-rich environment. To locate these stages, one must search through logs in various decomposition stages. Pupation occurs within the same woody materials, so careful examination of these logs and surrounding areas is essential. When searching, turning over logs and gently breaking apart decayed wood will reveal their presence.

Horned Passalus is an insect known for breaking down dead wood and plant remains. Both in their larval and adult stages, they play a crucial role in recycling nutrients in forest ecosystems. These insects possess specialized mouthparts and digestive systems that enable them to decompose tough plant fibers, contributing to soil fertility and promoting new plant growth. Interestingly, they also create and maintain intricate tunnels within the wood which aids in their decomposition process.
