Camponotus urichi

Camponotus urichi

Camponotus urichi is a tropical ant species found across northern South America, from Brazil and French Guiana through Colombia and Peru to Trinidad. Workers are distinctive with abundant silver appressed pubescence on the gaster and many erect hairs on the head, scape, and tibias. The larger major workers have a red or yellow head contrasting with a dark or black body. This species belongs to the subgenus Myrmosphincta and is closely related to C. sexguttatus. Little is known about their biology in the wild, but they have been collected in tropical forest habitats ^[1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical forests of northern South America, including Brazil, French Guiana, Colombia (Amazonas), Peru, and Trinidad ^[1]. They are a forest-dwelling species collected from tropical rainforest environments.
• Colony Type: Colony structure is unconfirmed. Based on typical Camponotus patterns, likely single-queen colonies, but this has not been directly documented.
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 10-12mm based on genus patterns
  • Worker: 5-9mm (majors larger, minors smaller) based on typical Camponotus worker range
  • Colony: Unknown, likely moderate (several hundred workers) based on genus patterns
  • Growth: Moderate, estimated based on typical Camponotus development
  • Development: Estimated 6-8 weeks at optimal temperature based on genus patterns (Development time inferred from related Camponotus species. Tropical origin suggests slightly faster development than temperate species.)
• Antkeeping:
  • Temperature: Keep at 24-28°C. Tropical species requiring warm conditions. A heating cable on one side of the nest creates a suitable gradient ^[1].
  • Humidity: Moderate to high humidity (60-80%). Tropical forest origin suggests they prefer damp conditions. Keep nest substrate consistently moist but not waterlogged.
  • Diapause: No, tropical species does not require hibernation. Maintain warm temperatures year-round.
  • Nesting: In captivity, Y-tong (AAC) nests or plaster nests work well. Provide a water tube for humidity. Based on tropical forest collection data, they likely prefer enclosed nest spaces with moderate moisture ^[1].
• Behavior: Workers are moderately active and forage both on the ground and possibly in lower vegetation. They are not particularly aggressive but will defend the nest. Escape prevention should be good, while not among the smallest ants, standard barriers are recommended. Foraging style is typical for Camponotus, they likely recruit nestmates to food sources.
• Common Issues: limited biological data makes care recommendations somewhat speculative, tropical species requires consistent warmth year-round, wild-caught colonies may have parasites or diseases, colonies may be slow to establish due to limited documented care information, humidity control is important, too dry can kill brood

Housing and Nest Setup

Camponotus urichi does well in Y-tong (AAC) nests or plaster formicariums. Provide a test tube water reservoir attached to the nest for humidity. These ants are not extremely large, so standard chamber sizes work well. Use a small outworld for foraging. Keep the nest area dark or covered, these forest ants prefer dim conditions. A layer of substrate in the outworld allows for natural foraging behavior. ^[1]

Feeding and Diet

Like most Camponotus, they accept sugar sources (honey, sugar water) and protein (insects). Feed them a mix of sugary liquids and small insects like fruit flies, mealworms, or crickets. Offer sugar water constantly and protein prey 2-3 times per week. Remove uneaten prey after 24 hours to prevent mold. They may also collect honeydew from aphids if kept in a naturalistic setup.

Temperature and Seasonal Care

Maintain temperatures between 24-28°C year-round. This is a tropical species that does not tolerate cool conditions. Use a heating cable or mat on one side of the nest to create a temperature gradient, allowing workers to regulate their own temperature. Do not allow temperatures to drop below 20°C for extended periods. No hibernation or diapause is needed, keep them warm throughout the year. ^[1]

Colony Founding

Queens are claustral, they seal themselves in a chamber and raise the first brood alone using stored fat reserves. Provide a founding queen with a small test tube setup with water through a cotton plug. Place the tube in darkness and do not disturb for 2-3 weeks. The queen will lay eggs and raise larvae through to nanitic workers. Once the first workers emerge, you can begin offering tiny food items and eventually connect to a larger nest.

Growth and Development

Development from egg to worker takes approximately 6-8 weeks at optimal temperature (around 26°C). The first workers (nanitics) are typically smaller than mature workers. Growth rate is moderate, colonies may take several months to reach 20-30 workers and a year or more to reach 100+. Be patient with this species as they are not fast growers. Consistent warmth and good nutrition will speed development.
