Crematogaster pilosa
Emery, 1895
Hairy-headed Acrobat Ant
Crematogaster pilosa is a to the southern Atlantic coast of the United States and some interior areas. It forms multiple spatially separated nests per colony, typically inhabiting tidal marshes, wet meadows, and other wetland environments. The species nests in stems, logs, and fallen branches. Its 'Hairy-headed Acrobat Ant' refers to its pilose (hairy) and the characteristic acrobat ant of raising the () over the when disturbed.

Habitat
Tidal salt marshes, intertidal salt marshes, wet meadows, and other wetland environments. Nests occur in stems, logs, and fallen branches. The exhibits a documented preference for highly connected within tidal marsh landscapes, suggesting that landscape connectivity influences colony distribution and structure.
Distribution

Behavior
Forms colonies with multiple spatially separated nests per colony. Exhibits preference for highly connected , indicating that landscape structure influences colony organization. Displays typical acrobat of raising the over the when disturbed.
