Stictoponera coxalis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Indo-Malaysian region: from India and Sri Lanka east to New Guinea, the Philippines, and southern China ^[4]. Recorded from Brunei, China, India (Andaman & Nicobar Islands, Karnataka), Indonesia (Java, Kalimantan, Sulawesi, Sumatra), Malaysia, Myanmar, Philippines, Singapore, Sri Lanka, Thailand, Vietnam ^[1][2][7]. Prefers secondary lowland wet forests ^[3].
• Colony Type: Colony structure is unconfirmed, no direct data on queen number or typical colony size in the wild.
• Size & Growth:
  • Queen: No measurements available from published literature
  • Worker: No total length measurements available from published literature
  • Colony: Unknown
  • Growth: Unknown
  • Development: Unknown (estimated 6-10 weeks based on typical Ponerinae patterns) (No direct development data exists for this species.)
• Antkeeping:
  • Temperature: Tropical species, aim for 24-28°C. Use a heating cable on one side of the nest to create a gradient. Avoid prolonged drops below 22°C.
  • Humidity: High humidity, think damp rainforest floor. Keep the nest substrate consistently moist but not waterlogged. Mist if needed and provide a water source.
  • Diapause: Unlikely, as a tropical lowland species, it probably does not require a true diapause. A slight winter temperature reduction (to ~20-22°C) may be beneficial but is not mandatory.
  • Nesting: Ground-dwelling species found in leaf litter and soil. In captivity, a naturalistic setup with moist soil substrate or a test tube with a water reservoir works well. They prefer dark, enclosed spaces for the nest chamber.
• Behavior: Predatory, typical of Ectatomminae. Workers actively hunt small invertebrates and possess a functional stinger for defense. They are moderately defensive when the nest is disturbed. Their medium size means escape prevention is important but not as critical as for tiny species.
• Common Issues: high humidity requirements can lead to mold problems if ventilation is poor, predatory diet means they need live prey, failure to provide suitable food often causes colony decline, temperature drops below 22°C can slow activity and affect brood development, wild-caught colonies may carry parasites that can decimate the colony in captivity, founding behavior is unconfirmed, making colony establishment from queens difficult

Temperature and Care

Stictoponera coxalis comes from tropical Southeast Asia, so it needs warm temperatures to thrive. Keep the nest area at 24-28°C, this matches the climate of its lowland wet forest habitat. Place a heating cable on one side of the nest to create a gentle temperature gradient, letting the ants choose their preferred spot. Avoid temperatures below 22°C for long periods, as this can slow activity and harm brood development. If your home stays consistently warm, room temperature may be enough, but most keepers will need supplemental heating. Keep the setup stable, no drafts or sudden temperature swings.

Feeding and Diet

Like other Ectatomminae ants, Stictoponera coxalis is predatory and needs a protein-rich diet. Offer small live prey such as fruit flies, small crickets, mealworms, and other appropriately-sized insects. They are likely ambush hunters that work individually, so prey should be small enough for a single worker to handle. Provide protein 2-3 times a week, and remove any uneaten prey after 24 hours to prevent mold. A sugar source like honey or sugar water may be accepted occasionally but should not be the main food. Always have fresh water available.

Nesting and Habitat

In the wild, S. coxalis lives in secondary forest leaf litter and upper soil layers. It prefers moist, shaded spots with plenty of decaying organic matter. For captive care, a naturalistic setup with moist soil substrate works well, mix potting soil with sand and keep it damp. A test tube with a water reservoir connected to a foraging area is also a good option. The nest chamber should be dark and enclosed, mimicking their natural retreats. Provide hiding spots and cover in the outworld. Good ventilation is key to prevent mold while keeping humidity high.

Behavior and Temperament

Workers are active foragers that hunt small invertebrates. They have a functional stinger and will defend the colony if disturbed, expect some defensive behavior. They are not overly aggressive but will sting if they feel threatened. Workers are medium-sized and can squeeze through small gaps, so use reasonable escape prevention. Activity may be higher in the evening or at night. Colony growth is probably gradual, do not expect rapid expansion. They do not form supercolonies and are not considered invasive.
