Ants of the World

Every ant tells a story. AntWeb provides tools for exploring the diversity and identification of ants (Hymenoptera: Formicidae).

These tools have been developed to encourage the study of ants, to facilitate the use of ants in inventory and monitoring programs, and to provide ant taxonomists with access to images of type specimens.

Currently AntWeb contains information on the ant faunas of several areas in the Nearctic and Malagasy biogeographic regions, and global coverage of all ant genera.
