Pheidole clypeocornis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Indomalaya region including Borneo, Brunei, Indonesia, Malaysia, the Philippines, Singapore, and Thailand. They live in lowland dipterocarp rainforests, nesting in rotting wood within leaf litter ^[2][1].
• Colony Type: Unconfirmed, no specific data on colony structure available.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements in literature.
  • Worker: Majors: ~1.8-2.3 mm TL ^[1], minors are smaller.
  • Colony: Unknown, no colony size data available.
  • Growth: Unknown
  • Development: Unknown, no development studies available. (Based on genus patterns, development may take several weeks at tropical temperatures.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. As a tropical species from lowland rainforests, they need warm, stable conditions ^[2].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, as they nest in rotting wood ^[1].
  • Diapause: No, as a tropical species, they do not require hibernation ^[2].
  • Nesting: Provide a nest that mimics rotting wood, such as Y-tong or plaster nests, with small chambers ^[1].
• Behavior: These are small, docile ants that are not aggressive. They are seed-storing ants, collecting and storing tiny seeds in their nest ^[1]. Workers forage on the ground and in leaf litter. Because of their very small size, escape prevention must be excellent, use fine mesh and tight-fitting lids ^[1].
• Common Issues: escape prevention is critical due to their very small size, they can squeeze through tiny gaps ^[1], high humidity requirements can lead to mold if ventilation is poor, slow growth may cause keepers to overfeed or disturb the colony too often, wild-caught colonies may have parasites that are difficult to detect, rotting wood nesting means the nest material can degrade if kept too wet

Nest Preferences

In the wild, Pheidole clypeocornis nests exclusively in rotting wood within leaf litter in lowland rainforests ^[1]. This means they need a nest environment that stays consistently moist and provides small cavities. Y-tong nests or plaster nests work well because you can control humidity and size chambers appropriately for their tiny majors at 1.8-2.3 mm TL ^[1]. Avoid dry, airy nests. The nest material should remain damp but never waterlogged. A humidity chamber or water reservoir connected to the nest helps maintain moisture levels.

Feeding and Diet

Pheidole clypeocornis is a seed-storing species, which is unusual for the genus, they collect and store tiny seeds in their nest rather than just consuming them immediately ^[1]. This means they likely have a varied diet including seeds and plant matter. For captive care, offer a mix of protein and carbohydrates. Protein sources like small insects (fruit flies, pinhead crickets, mealworms) should be offered regularly. Sugar water, honey, or commercial ant sweets provide carbohydrates. You can also offer tiny seeds, though their acceptance in captivity is unconfirmed. Feed every 2-3 days and remove uneaten food to prevent mold.

Temperature and Care

As a tropical species from Southeast Asian rainforests, Pheidole clypeocornis needs warm conditions year-round. Keep the nest area at 24-28°C. Room temperature may be sufficient if your home stays in this range, otherwise use a heating cable on one side of the nest to create a gentle temperature gradient. Never let temperatures drop below 20°C. Because they come from a stable tropical environment, avoid temperature fluctuations. No hibernation or winter rest is needed, maintain warm conditions throughout the year. The combination of heat and humidity requires good ventilation to prevent mold growth while still retaining moisture. ^[2]

Behavior and Temperament

These are docile, non-aggressive ants that are well-suited for colony observation. Major workers have distinctive horn-like projections on their clypeus, which makes them visually distinctive among Pheidole species ^[1]. They are ground-dwelling ants that forage in leaf litter. The seed-storing behavior is particularly interesting, unlike most ants that consume seeds, these ants cache them in their nest ^[1]. Workers are small but active. They are not known to be dangerous to keepers, but based on their subfamily, they likely have a sting, though no specific studies exist on this species. Their small size means they can escape through very tiny gaps, so use fine mesh on all openings.
