Camponotus rectangularis

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Neotropical region from Sinaloa and Nuevo León in northern Mexico to Bolivia and southern Brazil, found in tropical dry forests, cloud forests, and agricultural areas. Arboreal nester in preformed cavities ^[1][3][2].
• Colony Type: Monogynous with polydomous nesting, colonies occupy several cavities and can rapidly relocate ^[1].
• Size & Growth:
  • Queen: Estimated ~12-15 mm based on Camponotus genus patterns, direct measurement not documented
  • Worker: 4.3-9 mm ^[1]
  • Colony: Up to 820 workers ^[1]
  • Growth: Moderate
  • Development: 6-8 weeks (estimated based on typical Camponotus development) (Development time inferred from genus patterns, tropical species may develop faster at warmer temperatures)
• Antkeeping:
  • Temperature: Keep warm, roughly 24-28°C, based on tropical habitat ^[4].
  • Humidity: Provide a humidity gradient, mostly dry nest chamber with one small moist area, as they are arboreal and tolerate varying humidity ^[4].
  • Diapause: No, this is a tropical species that does not require hibernation ^[1].
  • Nesting: Arboreal setup with Y-tong, plaster, or naturalistic nests with twigs and branches. They readily accept artificial cavities ^[1][2].
• Behavior: Workers are generally calm and non-aggressive. They are diurnal, excellent climbers, and may escape if given the opportunity, use barrier gel on edges. They form polydomous colonies that can relocate quickly ^[1].
• Common Issues: escape prevention is important, they are excellent climbers and will find any gap., colonies can be parasitized by eucharitid wasps, quarantine new colonies ^[1]., polydomous colonies may split across multiple nest areas, ensure all sections stay connected., tropical species will become sluggish below 22°C, keep consistently warm., wild-caught colonies may have mites or other parasites, inspect and quarantine new introductions.

Housing and Nest Setup

Camponotus rectangularis is an arboreal species that naturally nests in preformed cavities like tree hollows, dead branches, and abandoned insect structures ^[1][2]. In captivity, they adapt well to Y-tong (AAC) nests, plaster nests, or naturalistic formicaria with twigs and branches ^[1]. Keep the nest humid but ensure ventilation to prevent mold, provide a water tube for humidity ^[4]. Because they are arboreal, include climbing structures and vertical space.

Feeding and Diet

These ants are true omnivores. In the wild, they forage for nectar, collect honeydew from aphids and membracids, prey on arthropods, and scavenge on carrion ^[1]. In captivity, offer sugar water or honey as a constant energy source, protein like mealworms or small crickets 2-3 times weekly, and occasional fruit or insects. Remove uneaten prey after 24 hours to prevent mold.

Temperature and Seasonal Care

As a tropical species, keep temperatures warm year-round, roughly 24-28°C, to support brood development ^[4]. They become sluggish below 22°C. No hibernation is required, maintain consistent warmth. A heating cable on one side of the nest can create a gradient for self-regulation.

Colony Structure and Behavior

Colonies are monogynous with a single queen and polydomous, meaning they occupy multiple connected cavities and can relocate rapidly ^[1]. Workers are diurnally active, foraging on low vegetation and tree trunks, and are not aggressive. They form mutualistic relationships with epiphytes like the orchid Myrmecophila tibicinis ^[1].

Health and Parasites

Eucharitid wasps parasitize brood, with global rates around 3.7% but up to 24% locally ^[1]. These wasps target worker and male pupae. Quarantine new colonies and monitor for unusual pupae. Regular observation and clean conditions help minimize issues.
