Species Overview

Polyrhachis lamellidens, commonly known as the Leaf-like Spiny Ant or Lamellate Spiny Ant, is a stunning species admired for its armor-like exoskeleton and fascinating parasitic nesting behavior. This species is part of the Polyrhachis genus, renowned for its ornate spines and metallic sheen.

Workers typically measure 7–10 mm in length and are covered in sharply pointed spines extending from the thorax and petiole, offering both defense and camouflage. Their black sheen, sculpted body texture, and elaborate spine formations make them one of Asia’s most ornamental ant species for advanced keepers.

Natural Habitat & Behavior

In nature, these ants inhabit forested environments, nesting under bark, within decaying wood, or beneath rocks. They are distributed across Southern China and parts of Southeast Asia. Polyrhachis lamellidens exhibits a rare and fascinating parasitic colony founding behavior.

Newly mated queens invade the nests of Camponotus japonicus (Japanese Carpenter Ant), eliminate the host queen, and gradually assume control over the worker population. This evolutionary strategy ensures successful colony establishment through biological infiltration, making their initial colony stages incredibly unique to observe.

Comprehensive Keeping Guidelines

Nest Type: Use wood-based nests or our specialized modular 3D-printed nests. Our 3D designs can be configured with textured surfaces that perfectly mimic the bark and rock crevices they naturally inhabit, providing a secure and enriching environment for this armored species.

Temperature: Maintain between 22–28°C (71–82°F) with stable conditions.

Humidity: Keep moderate to high humidity (60–80%), mimicking their natural forest microclimates.

Foraging Area: Include leaves, twigs, and climbing structures in the outworld for exploration and enrichment.

Feeding & Nutrition

Primary Diet: Live or pre-killed insects (fruit flies, crickets, mealworms).

Supplemental Nutrition: Provide constant access to sugar water, honey solutions, and diluted nectars.

Feeding Schedule: Offer food every 2–3 days; remove leftovers promptly to maintain hygiene.

Advanced Care Considerations

Colony Foundation: Understanding their parasitic founding behavior is crucial if keeping a single queen. Established starter colonies are highly recommended for stability.

Behavioral Sensitivity: Avoid vibrations or frequent nest disturbance, as they prefer stable, quiet environments.

Acclimation: New colonies may show stress during transport. Allow 1–2 weeks for acclimation in a quiet, shaded location. Minor worker loss is common and not alarming if the queen remains healthy.
