Dorymyrmex bicolor is a species commonly found in the southwesterndeserts of North America, and is often considered an outdoor pest. Nicknamed pyramid ants for their cone or pyramid-shaped propodeum, D. bicolor forms cone-shaped nests in dry, sandy deserts far from other ant colonies and uses aggressive interference methods when competing for food with any other colonies in the area. Despite its stigma as a pest (Field 2007), D. bicolor has a positive influence in plant distribution and diversification. This ant species distributes seeds of the plants it interacts with along foraging routes (Cuautle 2005, Nash 2004, Bestelmeyer 2005).
