Lepisiota wroughtonii

Lepisiota wroughtonii

Lepisiota wroughtonii is a medium-sized ant native to South Asia, found across India, Sri Lanka, and southern China. Workers measure 2-2.5mm and have a distinctive black body with light brown antennae, mandibles, and yellowish-white tarsi. Their body is dull and covered with relatively dense pubescence, which distinguishes them from the similar Lepisiota rothneyi (which has a shiny body). They have three small ocelli on the head and lack spines or teeth on the propodeum and petiole. These ants are primarily arboreal, often collected from tree trunks and vegetation using beating techniques and honey baits ^[1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: India, Sri Lanka, and southern China. Found across multiple Indian states including Himachal Pradesh, Kerala, Tamil Nadu, Uttarakhand, and West Bengal. They inhabit tropical to subtropical regions and are typically collected from tree trunks and vegetation, suggesting arboreal or elevated nesting preferences ^[1][2].
• Colony Type: Colony structure is unconfirmed. Based on typical Lepisiota genus patterns, they likely form single-queen colonies, but this has not been directly documented.
• Size & Growth:
  • Queen: Not documented in available research, estimated 6-8mm based on genus patterns
  • Worker: 2-2.5mm ^[1]
  • Colony: Unknown, no colony size data available
  • Growth: Moderate, inferred from similar tropical ants
  • Development: Estimated 6-8 weeks at optimal tropical temperatures based on related species patterns (Direct development data unavailable, estimate based on typical Formicinae development at 24-28°C)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Their native range spans tropical and subtropical India and Sri Lanka, so they prefer warm conditions. A gentle temperature gradient allows them to regulate.
  • Humidity: Moderate humidity around 50-70%. Their arboreal habitat suggests they tolerate drier conditions than ground-nesting species. Provide a water tube but avoid overly damp nests.
  • Diapause: Unlikely, tropical species from India and Sri Lanka probably do not require hibernation. They may show reduced activity during cooler months but no true diapause is expected.
  • Nesting: Based on collection methods (tree trunks, vegetation beating), they likely prefer arboreal or elevated nest sites. In captivity, a Y-tong or acrylic nest with narrow chambers works well. They may accept test tube setups but appreciate vertical space. Avoid very damp substrates, keep them relatively dry.
• Behavior: These ants are relatively active foragers and are attracted to sweet baits like honey ^[1]. Workers are small at 2-2.5mm, so escape prevention should be moderate, standard barriers work but ensure no small gaps exist. They are not known to be particularly aggressive. Their small size and arboreal nature suggest they are agile climbers. Temperament appears calm, not documented as overly defensive or aggressive.
• Common Issues: lack of documented care information makes reliable husbandry challenging, small worker size may require fine mesh barriers to prevent escapes, tropical species may struggle in cool or dry environments, no documented colony founding behavior, may be difficult to establish from queen, dietary requirements beyond sugar acceptance are unknown

Appearance and Identification

Lepisiota wroughtonii workers are small but distinctive ants measuring 2-2.5mm. They have a black body with light brown antennae, mandibles, and yellowish-white tarsi. The most distinguishing feature is their dull, densely pubescent body, this sets them apart from the similar Lepisiota rothneyi, which has a shiny body with sparse pubescence. They have three small ocelli on their head, and unlike many ants, they lack spines or teeth on both the propodeum and petiole. The head is subquadrate (slightly wider at the back), and the antennal scape extends about one-quarter of its length beyond the posterior head margin ^[1].

Natural Habitat and Collection

These ants are native to South Asia, found across India (Himachal Pradesh, Kerala, Tamil Nadu, Uttarakhand, West Bengal), Sri Lanka, and southern China. They are primarily collected from tree trunks and vegetation, suggesting they are arboreal or at least prefer elevated locations. Researchers collect them using multiple techniques: hand collection from tree trunks, beating vegetation to dislodge them, setting honey baits, and occasionally using pitfall traps. This suggests they are generalist foragers that readily come to sugar sources ^[1][3].

Housing and Nest Preferences

Based on their natural collection from tree trunks and vegetation, these ants likely prefer arboreal-style setups. In captivity, a Y-tong or acrylic formicarium with narrow chambers works well. They are small ants at 2-2.5mm, so ensure your nest chambers are appropriately scaled. They seem to prefer drier conditions than many tropical ants, their arboreal lifestyle suggests they are accustomed to better air circulation. Provide a water tube for humidity but avoid creating a constantly damp environment. A test tube setup can work for founding colonies, but be prepared to move them to a more spacious formicarium as the colony grows.

Feeding and Diet

Field research shows these ants are readily attracted to honey baits, confirming they accept sugar sources ^[1]. In captivity, offer sugar water, honey, or diluted syrup regularly. For protein, they likely accept typical ant foods like small insects, but specific prey preferences are undocumented. Start with small prey items like fruit flies or small mealworm pieces. Feed protein roughly twice weekly, and keep sugar water available at all times. Remove uneaten food promptly to prevent mold.

Temperature and Seasonal Care

As a tropical species from India and Sri Lanka, Lepisiota wroughtonii prefers warm conditions. Maintain temperatures between 24-28°C. They likely tolerate slightly higher temperatures given their native range, but this is not well documented. No hibernation or diapause is expected, they come from regions without cold winters. During cooler months, room temperature may be sufficient, but monitor for any signs of reduced activity. A small heating cable on one side of the nest can help maintain optimal temperatures if your room runs cool.

Colony Development

Specific development timelines are not documented for this species. Based on typical Formicinae development patterns at tropical temperatures, expect roughly 6-8 weeks from egg to first worker at 24-28°C. Queens are estimated at 6-8mm based on genus patterns, though this is not directly documented. Colony size in the wild is unknown. Starting a colony from a wild-caught queen may be challenging since their founding behavior is unconfirmed, they are likely claustral (queen seals herself in and lives off stored fat) like most Lepisiota species, but this needs confirmation.
