Pseudomyrmex peperi is an obligate Acacia inhabitant. Here, a worker gathers a lipid-rich Beltian body from a leaf tip. The plant feeds the ants in exchange for protection from herbivores and competing plants. Armenia, Belize.

Not all of the thorns on a swollen-thorn Acacia house the ants' larvae, but those that do are heavily guarded. Here, Pseudomyrmex spinicola patrol a nest entrance, ready to use their stings if the photographer approaches too close. Chiriqui, Panama.

Biology:

Most species of Pseudomyrmex nest in dead twigs or stems of woody plants. Some have become specialized inhabitants of live plant domatia, such as the acacia-ants that occupy swollen-thorn acacias.

Identification:

Worker: antennae 12-segmented; mandibles with proximal tooth on basal margin; eyes large and elongate, more than 1.5 times as long as wide. Other characters as in subfamily.

Notes:

The genus is predominantly Neotropical, with only two species occurring in California.
