Camponotus ctenopilosus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Southern Brazil (Paraná and Rio de Janeiro states), likely in forested areas with rotting wood and moderate humidity ^[1][2].
• Colony Type: Potentially polygynous, as the type series includes two dealate queens, suggesting colonies may have multiple egg-laying queens ^[2].
• Size & Growth:
  • Queen: ~10 mm ^[1]
  • Worker: Major workers: 8-9 mm, minor workers: ~4.5 mm ^[1]
  • Colony: Unknown, no specific data on colony size
  • Growth: Moderate, inferred from Camponotus genus patterns
  • Development: 6-10 weeks estimated based on typical Camponotus development (Development time is genus-level inference, specific timing for this species is unconfirmed)
• Antkeeping:
  • Temperature: Keep warm and stable, roughly low-to-mid 20s°C, with a gradient to allow self-regulation ^[1].
  • Humidity: Keep the nest substrate consistently moist but not waterlogged, based on their forest habitat ^[1].
  • Diapause: Unknown, no specific data on diapause requirements
  • Nesting: Prefer nests that mimic rotting wood, such as Y-tong, plaster, or naturalistic setups with damp substrate ^[1].
• Behavior: Typically calm and non-aggressive toward keepers, but will defend the nest. Workers forage for protein and carbohydrates. Escape risk is moderate due to worker size, standard barriers are sufficient. Defense involves spraying formic acid, as typical for Formicinae.
• Common Issues: limited availability, this species is rare in captivity with few known colonies, lack of species-specific care data requires reliance on genus-level assumptions, founding behavior is unconfirmed, which may affect colony establishment, polygynous structure, if confirmed, might need larger nest spaces

Appearance and Identification

Major workers of Camponotus ctenopilosus are 8-9 mm long with a dark reddish-black body, orange legs, and a golden gaster caused by dense appressed hairs that form a combed pattern ^[1]. Minor workers are around 4.5 mm and mostly black with lighter antennae. Queens are about 10 mm and share the golden gaster pattern. The clypeus is bulging in majors, and the species can be separated from similar ants by its hair pattern ^[1].

Nest Preferences

In captivity, provide nests that mimic natural conditions, such as Y-tong, plaster, or setups with damp soil and wood pieces. Keep the substrate moist but not waterlogged, as this species likely inhabits humid forest floors ^[1].

Feeding and Diet

You should offer protein sources like insects 2-3 times per week and constant carbohydrates like sugar water or honey. Remove uneaten prey after 24-48 hours to prevent mold ^[1].

Temperature and Seasonal Care

Maintain temperatures around 22-26°C with a gradient for self-regulation. Avoid extremes below 15°C or above 30°C. Diapause requirements are unknown, but a slight cool period in winter may be beneficial based on genus patterns ^[1].

Colony Structure and Founding

The type series suggests polygynous colonies, but founding behavior is unconfirmed. If you attempt founding, use a test tube setup, but note that specific methods are not documented for this species ^[2].

Behavior and Temperament

Workers are generally docile but will spray formic acid if threatened. They are active foragers and communicate via chemical trails. Escape risk is moderate, use standard barriers like Fluon on rims ^[1].
