Fakta

Mounds are surrounded by bare ground, so they do not burn during fires.1

A mature colony can have up to 20,000 workers and one queen, and its nest can reach 5 metres (16 ft) deep.1

Honey ants (Myrmecocystus mexicanus) often nest close to western harvester ant colonies and feed on dead or dying workers.1

A queen mates with 2 to 11 different males, with an average of 6.3.1

Workers usually change their jobs as they age, and they forage towards the ends of their lives. A worker lives for an average of six months.1

In cooler months, workers forage throughout the day. In summer they forage only from 5–11 am and 3–9 pm.1
