Pheidole lamellinoda

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to the Indian mainland (Delhi, Maharashtra, Meghalaya) and the Socotra Archipelago in Yemen. Found at elevations around 940 m on Socotra. Records suggest the species is rather local in India ^[3][4]. No ecological information is available about its natural habitat.
• Colony Type: Colony structure is unconfirmed. Based on typical Pheidole patterns, likely single-queen (monogyne), but no data confirms this. Major and minor worker castes are present.
• Size & Growth:
  • Queen: Unknown – size not described in available literature.
  • Worker: 4.5-5 mm ^[1]
  • Colony: Unknown – no colony size data available.
  • Growth: Unknown – no development data available.
  • Development: Inferred from typical Pheidole patterns: 6-10 weeks at warm temperatures. (No development studies exist for this species. Related Pheidole species develop from egg to worker in 6-10 weeks depending on temperature.)
• Antkeeping:
  • Temperature: Keep at 24-28°C, inferred from its tropical/subtropical range ^[3][4]. Provide a gentle gradient so workers can self-regulate.
  • Humidity: Provide a moderate moisture gradient: keep one part of the nest substrate slightly moist but not waterlogged, and let the rest dry out a bit. This matches the dry-to-moderate conditions of its Indian and Socotran range.
  • Diapause: Unknown – likely minimal or no true diapause given the tropical/subtropical range. You may see reduced activity in cooler months, just feed less often rather than forcing cold dormancy.
  • Nesting: Nesting preferences are unconfirmed. Most Pheidole nest in soil, under stones, or in rotting wood. Start with a test tube for founding, larger colonies can move to a Y-tong or naturalistic setup.
• Behavior: Temperament is unconfirmed, but Pheidole are generally non-aggressive and docile. Workers are small and unlikely to sting. Escape risk is moderate due to their small size – standard barriers like fluon work well. They scavenge and may collect seeds, typical for the genus.
• Common Issues: lack of species-specific care data – start with generic Pheidole guidance and adjust based on your colony's response, colony founding can be slow, no specific timeline is known, so patience is needed, maintain good escape prevention despite their small size, no confirmed diet preferences – offer standard Pheidole foods and observe what they accept, winter care is uncertain – watch for reduced activity and adjust feeding as needed

Appearance and Identification

Pheidole lamellinoda is a small ant with a clear size difference between major and minor workers. Workers measure 4.5-5 mm total length ^[1]. Color is distinctive: head reddish-yellow, mesosoma and petiole yellow, gaster brownish-yellow ^[2]. The key marker is the ventral forward-directed translucent lobe on the petiole of major workers – this is unique among related species ^[3]. Minor workers lack this lobe and can be hard to tell apart from other Pheidole, especially Pheidole indica which has a distinctly lower postpetiolar node ^[3]. The major worker's head has a striated front half, while the back half is smooth and shiny, and the rear edge of the head is strongly concave ^[2].

Distribution and Habitat

Pheidole lamellinoda has a scattered distribution. It's native to mainland India, found in Delhi, Maharashtra, and Meghalaya, where records suggest it is rather local ^[3][4][1]. It also occurs on the Socotra Archipelago in Yemen, over 2000 km from India – an unusual pattern. Specimens were collected at around 940 m elevation on Socotra (Adho Dimello base camp) ^[3]. The species hasn't been found in Arabia and isn't reported as introduced elsewhere ^[3]. No habitat or ecological details are known.

Nest Preferences and Housing

Nesting preferences are not documented. Most Pheidole nest in soil, under stones, or in rotting wood. For captive care, start with a test tube setup for founding – it gives the humidity and darkness queens need. Once the colony reaches around 30 workers, you can move them to a Y-tong or plaster nest, or a naturalistic setup with soil. Since workers are under 5 mm, chambers should be small. Make sure escape barriers are in place – they're small enough to slip through tiny gaps.

Feeding and Diet

Diet preferences are unconfirmed for this species. As a genus, Pheidole are omnivores with a fondness for seeds and protein. Start with standard ant food: small protein sources (fruit flies, pinhead crickets, tiny mealworms) offered 2-3 times a week, and constant access to sugar water or honey. Provide appropriately small prey items. Watch your colony and adjust. Remove uneaten food after 24-48 hours to avoid mold.

Temperature and Seasonal Care

No specific temperature data exists. Based on its tropical to subtropical range in India and Socotra, aim for 24-28°C ^[3][4]. A slight gradient helps workers self-regulate. Room temperature (20-24°C) may be okay, but warmer likely boosts growth. Regarding diapause: the species comes from areas with little cold, so true hibernation probably isn't needed. You may notice less activity in cooler months – just cut back feeding rather than trying to force dormancy.

Colony Development and Growth

No development timeline data exists for Pheidole lamellinoda. Based on typical Pheidole patterns, expect eggs to become workers in about 6-10 weeks at 26-28°C. The first workers (nanitics) will be smaller than later ones. Colony growth starts slow as the queen focuses on a small initial brood, then speeds up as more workers help. Be patient during founding – this species has no documented timeline, so observe and adjust care accordingly.
