Temnothorax
Acorn Ants and Allies
Temnothorax is a genus of small ants in the subfamily Myrmicinae containing over 500 species worldwide. Workers are typically small with mesosoma length around 0.7–1.5 mm. Colonies are generally monogynous with small populations, often fewer than 100 workers, though some species maintain multiple satellite nests. The genus has become an important model system for studying social behavior, caste differentiation, and collective decision-making in ants due to their small colony size and ease of laboratory maintenance.
Temnothorax pergandei
Pergande's Acorn Ant
Temnothorax pergandei is a small ant species in the family Formicidae, commonly known as Pergande's Acorn Ant. Like other members of its genus, it is a cavity-nesting species that typically inhabits pre-existing spaces such as hollow acorns, twigs, or other small plant cavities. The species was first described by Emery in 1895 and is part of a diverse genus containing over 350 species worldwide, with approximately 60 species known from North America.
