Myrmecocystus navajo is a honeypot ant of the southern United States and northern Mexico. Colonies exploit seasonal pulses of nectar and honeydew and preserve part of the surplus in replete workers deep underground.

Southwestern United States and northern Mexico.
Desert, dry grassland, sandy flats and open scrub.
Often crepuscular or nocturnal in hot weather.
Nectar, honeydew and arthropod food.
Deep soil nests with replete workers suspended from chamber ceilings.
A replete’s abdomen can expand until the worker is unable to walk normally.
Stored food helps the colony survive long dry intervals.
The nest is much deeper and more complex than the small surface entrance suggests.
