Natural Habitat

Typically found in forested areas, nesting in dead wood, hollow logs, tree stumps, and sometimes in structural wood in buildings.

Diet & Feeding

Omnivorous; they consume plant juices, honeydew from aphids, other insects, and sugary or protein-rich food scraps found in human environments.

Behavior Patterns

They do not eat wood but excavate it to build nests. They are mostly nocturnal and exhibit a complex social structure with a founding queen, as seen in this test tube setup tending to her first brood (nanitics).

Risks & Benefits

Benefits include aerating soil and aiding in the decomposition of dead wood. Risks include potential structural damage to wooden buildings if a large colony establishes itself inside damp wood.
