Lepisiota chapmani

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Philippines, specifically Negros Oriental and Mindanao islands in the Indomalaya region. Found in mountainous areas, nesting in plant galls on dead branches ^[1][2][3].
• Colony Type: Colony structure is unconfirmed for this species. Based on related Lepisiota patterns, likely single-queen colonies, though some genus members can form multi-queen colonies.
• Size & Growth:
  • Queen: 4.5mm ^[1]
  • Worker: 2.5-2.8mm ^[1]
  • Colony: Unknown for this species
  • Growth: Unknown, likely moderate based on genus patterns
  • Development: Estimated 6-10 weeks based on typical Formicinae development (No specific development data exists for L. chapmani. This is an estimate based on related Formicinae species.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Being a tropical Philippine species, they prefer warm conditions. A heating cable on one side of the nest creates a suitable gradient.
  • Humidity: Moderate to high humidity. Their natural habitat in Philippine mountains provides humid conditions. Keep nest substrate moderately moist but not waterlogged.
  • Diapause: Unlikely, as a tropical species from the Philippines, they probably do not require a true diapause.
  • Nesting: In nature, they nest in plant galls on dead branches. In captivity, a naturalistic setup with cork or wooden elements works well. Y-tong (AAC) nests with narrow chambers can also work, but include some wood or bark material for them to explore.
• Behavior: This species is not well-documented in captivity. Based on genus behavior, they are likely active foragers that search for honeydew and small prey. Workers are small (2.5-2.8mm) so escape prevention must be excellent, use fine mesh barriers. Temperament is likely moderate, they are not typically aggressive but will defend their nest if threatened.
• Common Issues: small worker size means escapes are likely without fine mesh barriers, limited species-specific care information means some trial and error may be needed, wild-caught colonies may have parasites or be stressed from collection, humidity requirements may be tricky to balance, too dry causes problems, too wet leads to mold

Housing and Nest Setup

Lepisiota chapmani naturally nests in plant galls on dead branches, indicating they prefer enclosed spaces with some wood material. For captivity, a naturalistic setup with cork, twigs, or small wood pieces works well. You can also use a Y-tong (AAC) formicarium, but consider adding some organic material or providing an outworld with wood debris for them to explore. Because workers are only 2.5-2.8mm, escape prevention is critical, use tight-fitting lids and fine mesh on any ventilation. A small test tube setup can work for founding colonies, but be prepared to move them to a larger setup as the colony grows. ^[1]

Feeding and Diet

Like other Lepisiota species, L. chapmani likely feeds on honeydew from aphids and scale insects, plus small insects for protein. In captivity, offer sugar water or honey water as a constant energy source. For protein, provide small live prey like fruit flies, pinhead crickets, or mealworm pieces. Feed protein 2-3 times per week, and remove any uneaten prey after 24 hours. Since this species is rarely kept, acceptance of commercial ant foods is unknown, stick to natural prey and sugar sources until you observe what they accept.

Temperature and Heating

As a tropical species from the Philippines, L. chapmani needs warm conditions. Keep the nest area at 24-28°C. You can use a heating cable or heating mat on one side of the nest to create a temperature gradient, allowing ants to move between warmer and cooler areas. Place the heating element on top of the nest, not underneath, to avoid drying out the substrate too quickly. Room temperature may be sufficient if your home stays in the low-to-mid 20s°C range, but monitor colony activity, if workers seem sluggish, provide gentle heating.

Humidity and Moisture

This species comes from humid mountain regions of the Philippines, so they need moderate to high humidity. Keep the nest substrate consistently moist but not waterlogged. The substrate should feel damp to the touch. You can provide a water tube in the outworld for drinking water, and mist the nest occasionally if it starts drying out. However, avoid constant misting, too much moisture leads to mold problems. Leave some drier areas in the nest so ants can self-regulate their humidity preferences.

Growth and Development

Specific development time from egg to worker is unknown for this species. Based on typical Formicinae development patterns, expect 6-10 weeks at optimal temperatures (around 26°C). The first workers (nanitics) will be smaller than mature workers. Growth rate is likely moderate. Be patient with founding colonies, it can take several months to see significant growth. Once the first workers arrive, the colony typically accelerates as the queen can focus on egg production rather than caring for brood alone.
