Leptogenys
Leptogenys processionalis
Care Guide
Leptogenys processionalis is a fascinating and visually striking species, known for its dramatic group raiding behavior that gives these ants their common name—processional ants. Workers form orderly, single-file columns as they march in search of prey, a spectacle that is both mesmerizing and efficient. Within the colony, there is no pronounced polymorphism; the queen measures 10–12 mm, while workers range from 8–10 mm, all sharing a sleek, elongated body and powerful mandibles adapted for capturing live prey.
These ants are specialized predators with a strong preference for termites, though they will readily accept other soft-bodied insects. Their hunting style is highly coordinated: a scout will recruit nestmates, and together they will overwhelm prey through sheer numbers and rapid, stinging attacks. This makes feeding a dynamic and engaging process for the keeper, but it also means that a steady supply of live or freshly killed insects is essential. Unlike granivorous species, Leptogenys processionalis cannot thrive on seeds or sugars; their diet is almost exclusively protein-based.
Care difficulty
Keeping Leptogenys processionalis is considered advanced, primarily due to their semi-claustral founding and specialized dietary needs. The queen must be fed regularly during the initial stages, as she cannot rely solely on stored reserves. Furthermore, the colony’s high humidity requirements and sensitivity to disturbance demand careful attention. This species is best suited for experienced keepers who are comfortable managing a demanding, yet highly rewarding, predator ant.
Housing
Provide a formicarium that maintains consistent humidity between 70 and 90%. A substrate that retains moisture well—such as a mix of sand and clay or a natural earth setup—works best. The nest should be kept at a steady temperature of 24–28°C, with no need for a hibernation period. Because these ants are sensitive to vibrations and bright light, place the formicarium in a quiet, dimly lit area. An outworld with ample foraging space is recommended, as the colony will engage in frequent raiding trips. Ensure that the outworld has a secure lid, as these ants are capable climbers and may attempt to escape when excited by prey.
First days after purchase
Upon receiving your Leptogenys processionalis colony, transfer the ants gently into a prepared formicarium with high humidity. Place a small drop of honey water or sugar water near the queen if she appears stressed, though her main requirement will be a protein source. Offer a single small insect—such as a freshly killed cricket or termite—within the first 24 hours. Observe without disturbing; the queen will need to acclimate and begin laying eggs. Avoid bright lights and tapping on the enclosure. Over the first week, maintain humidity by moistening the nest chamber slightly, and provide small, appropriately sized prey items every two to three days. Patience is key: once the first workers emerge, the colony’s confidence will grow, and you will soon witness the remarkable processional raids that make this species a true gem for the dedicated ant keeper.
