Summary

Dolichoderus is a diverse genus of ants found worldwide, characterized by their robust morphology and nesting behaviors that vary greatly between species.

Physical Characteristics

Workers typically about four millimetres in body length; thick, inflexible, and strongly sculptured integument; saw-like flange on the underside of the head near the base of mandibles in some species; deeply impressed longitudinal suture in the central plate of metathorax; concave posterior face of the propodeum; gaster and alitrunk separated by a single segment (petiole); cloacal orifice is a horizontal slit surrounded by stiff erect bristles.

Identification Tips

Look for the thick and sculptured body structure, the saw-like flange of the mandibles, and the distinct metathoracic features.

Habitat

Nesting in soil, curled leaves, hollow plant stems, and in cartons made from chewed wood mixed with secretions. Some species nest underground in northern parts of the United States while others may live in trees in the south.

Distribution

Worldwide, found on all continents except Antarctica.

Diet

Feed on small arthropods and tend to sap-sucking insects like aphids and scale insects which excrete honeydew.

Reproduction

Some species are believed to be polygynous with multiple queens in a single nest.

Ecosystem Role

Act as predators of small arthropods and tenders of sap-sucking insect populations, playing a role in local ecosystems.

Evolution

The genus Dolichoderus has undergone taxonomic revisions, including the synonymization of other genera such as Monacis and Hypoclinea.
