Summary
Aphaenogaster is a genus of myrmicine ants known for their agility and opportunistic scavenging behavior. They build distinct funnel-shaped nests and have a worldwide distribution, with significant ecological roles in bioturbation.
Physical Characteristics
Slender body with long legs; four-segmented antennae; single worker caste.
Identification Tips
Distinguishable from Pheidole by having only one worker caste and 12-segmented antennae; major and minor workers present in Pheidole.
Habitat
Worldwide, except in South America south of Colombia, sub-Saharan Africa, and Antarctica. Often build nests in Australia.
Distribution
Worldwide distribution with approximately 200 species described, including 18 fossil species.
Diet
Opportunistic scavengers, primarily feeding on tended aphids and trapped arthropods.
Ecosystem Role
Bioturbation, important in soil and landscape processes, particularly in Australia.
Economic Impact
Nests can be problematic on golf courses, pastures, and unsealed airstrips due to fragile surface.
