(Roger, 1863)

Schaumii-group Acorn Ants

Temnothorax schaumii is a small in the Temnothorax, commonly known as the Schaumii-group Acorn Ants. First described by Roger in 1863, it was historically classified under the genus Leptothorax before taxonomic revision placed it in Temnothorax. The species belongs to a genus of cavity-nesting ants that frequently inhabit acorns, twigs, and other small preformed cavities. Like other Temnothorax species, it exhibits small colony sizes and specialized nesting habits.
