Plagiolepis rogeri

Quick Summary

• Difficulty: Easy
• Origin & Habitat: India, specifically Karnataka and West Bengal, in tropical and subtropical regions ^[2].
• Colony Type: Colony structure is unconfirmed. No specific data on queen number or social structure is available.
• Size & Growth:
  • Queen: Size data unavailable, no total length measurements provided for queens.
  • Worker: 1.5 mm ^[1]
  • Colony: Estimated up to 500 workers at maturity, based on typical Plagiolepis patterns.
  • Growth: Moderate
  • Development: Estimated 6-8 weeks at optimal temperature, based on related Formicinae species. (Timeline is inferred, this species has not been directly studied for development times.)
• Antkeeping:
  • Temperature: Keep at 22-26°C, inferred from their tropical Indian habitat ^[1].
  • Humidity: Keep substrate lightly moist but allow some drying between waterings, based on typical moderate humidity needs ^[1].
  • Diapause: Unknown, tropical species may not require hibernation, but no specific data exists.
  • Nesting: Small chambers work best for their tiny size. Test tubes with cotton stops or Y-tong nests with fine chambers are suitable.
• Behavior: Workers are docile and non-aggressive, with no known stinging ability. Their tiny size (1.5 mm) makes escape prevention critical, they can squeeze through small gaps ^[1].
• Common Issues: escape prevention is critical due to their tiny 1.5 mm size., small colony size means slower population growth, patience is required., test tube setups need careful water management to avoid flooding., wild-caught colonies may have parasites affecting survival., overfeeding can lead to mold issues in small nests.

Housing and Nest Setup

Because Plagiolepis rogeri workers are only 1.5 mm, they need appropriately scaled housing. Test tube setups work well with small-diameter tubes and cotton stops for water reservoirs. For formicariums, choose nests with small chambers and narrow tunnels, such as Y-tong nests with fine chambers. Avoid large open spaces. Escape prevention is critical, use fine mesh (0.5 mm or tighter) on all openings and apply fluon barriers ^[1].

Feeding and Diet

These ants are omnivorous with a preference for sweet liquids. Offer sugar water, honey, or diluted honeydew regularly. For protein, provide small prey like fruit flies or pinhead crickets, sized appropriately for their 1.5 mm workers. Feed protein every 2-3 days and keep sugar sources available constantly.

Temperature and Seasonal Care

Plagiolepis rogeri originates from warm climates in India, so keep temperatures at 22-26°C. Room temperature within this range is usually sufficient. If cooler, use a heating cable on one side to create a gradient. In winter, a slight reduction to 18-20°C may be appropriate if the colony shows reduced activity, but hibernation is unlikely for this tropical species.

Colony Development and Growth

This species has not been directly studied for development times. Based on related Formicinae ants, expect first workers to emerge roughly 6-8 weeks after egg laying at optimal temperature. Initial growth is slow, then accelerates once workers emerge. Colonies likely max out at a few hundred workers.

Behavior and Temperament

Plagiolepis rogeri is peaceful and non-aggressive. Workers are active foragers but pose no threat due to their small size. They lack painful stings or chemical defenses. The main concern is escape ability, excellent prevention is mandatory ^[1].
