Information reviewed15 July 2026
Harpegnathos saltator is a large-eyed predatory ant from the Indian region. Workers hunt mainly alone, using vision and long mandibles, and can jump to escape or intercept prey. Its social system is unusually flexible: after the queen dies, workers compete and a small number become reproductive gamergates.

Southern India and Sri LankaBroad documented localities — not a complete range map.
Primarily southern India, with related named forms recorded from Sri Lanka. Records outside this core range require careful taxonomic checking.
Warm ground habitats, scrub, open woodland and field margins, with soil nests commonly placed beneath vegetation.
Workers forage singly during cooler daylight periods, especially morning and late afternoon, with reduced activity during the hottest hours.
A specialised predator of live arthropods. Workers rely strongly on vision when stalking and capturing prey.
Relatively small colonies, often tens to a few hundred workers. A founding queen may later be replaced functionally by several mated reproductive workers.
What makes this species remarkable?
Workers can perform synchronised jumps using the middle and hind legs, both in escape and prey capture.
When a colony loses its queen, workers duel for status; successful individuals become egg-laying gamergates.
The transition to gamergate involves reversible changes in behaviour, physiology, longevity and even brain structure.
