Camponotus modoc
Western Carpenter Ant, Western Black Carpenter Ant
Camponotus modoc, the western carpenter ant, is a large black ant species native to western North America. Workers exhibit polymorphism, ranging from 7 to 13 mm in length, with dark red legs contrasting against a black body. The species constructs nests in dead wood, including forest logs and human structures, and is known for its mutualistic associations with aphids, particularly Cinara occidentalis on white fir. Research demonstrates trail fidelity and colony recognition abilities, with workers returning to specific aphid colonies even after displacement.

Western Acorn Ant
Temnothorax rugatulus is a small myrmicine ant species native to western North America, notable for its sophisticated collective decision-making behaviors and remarkable polymorphism in queen size. The species exhibits two distinct queen morphs: large macrogynes associated with single-queen (monogynous) colonies, and smaller microgynes found in multiple-queen (polygynous) colonies. This species has become an important model organism for studying social insect behavior, communication, and the molecular mechanisms underlying caste determination and phenotypic plasticity.
