Species Overview

Cerapachys sulcinodis major, commonly known as the Giant Grooved-node Ant, is the large-bodied regional morph of the Cerapachys sulcinodis complex, belonging to the army ant subfamily Dorylinae. This rare Chinese variant features significantly larger size (12–14 mm), stronger mandibles, and more coordinated predatory behavior than its Southeast Asian counterparts. As a specialized predator species, it demonstrates advanced group hunting strategies and a highly social organization — ideal for professional ant keepers seeking to observe natural predatory coordination.

Morphological Characteristics

• Worker Size: 12–14 mm
• Body Structure: Elongated and muscular with a distinctive longitudinally grooved petiole node
• Notable Features: Reinforced head capsule and thick mandibles for powerful hunting

Natural Habitat & Behavior

Native to southern China and northern Southeast Asia, these ants inhabit soil-based environments and build semi-permanent underground nests. They hunt in coordinated groups, targeting small arthropods and insect larvae. Unlike nomadic army ants, C. sulcinodis major maintains fixed nest sites but still shows remarkable predation efficiency and collective aggression, making it one of the most exciting Dorylinae species to study in captivity.

Comprehensive Keeping Guidelines

Nest Type: Use secure soil-based setups or our specialized modular 3D-printed nests. Ensure the nest provides stable conditions and secure containment for these active hunters.

Temperature: Maintain between 22–26°C (71–79°F). Avoid rapid or extreme temperature changes.

Humidity: Keep nest humidity around 60–70%.

Feeding & Nutrition

Primary Diet: Feed small insects, larvae, and soft-bodied arthropods. Group hunting is a key behavior, so live or freshly killed prey is ideal.

Supplemental Nutrition: Provide occasional diluted honey or sugar water for energy balance.

Feeding Schedule: Feed every 2–3 days, adjusting portions based on colony activity.

Advanced Care Considerations

Colony Stability: Avoid frequent nest relocations; stability encourages normal behavior and brood development.

Predatory Behavior: Provide natural hunting opportunities in a controlled outworld whenever possible.

Acclimation: Some stress or minor worker loss during international transit is a normal biological response. Allow 1–2 weeks for the colony to stabilize and resume coordinated foraging.
