Camponotus edmondi

Camponotus edmondi

Camponotus edmondi is a medium-sized carpenter ant native to Madagascar, the Comoro Islands, and Mayotte. Workers are mostly black with brown to light brown legs and antennae. Minor workers have relatively large eyes and an elongated head, while major workers have broader heads with scattered erect hairs on the pronotum. This species belongs to the Camponotus edmondi species group within the Mayria subgenus. Unlike many carpenter ants that nest in wood, C. edmondi is arboreal, it nests in dead twigs and branches above ground and forages in trees and shrubs. They inhabit eastern littoral forests and coastal areas, including human-modified and disturbed habitats ^[1].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Madagascar, Comoro Islands, and Mayotte Islands. Found in eastern littoral forests, coastal forests, and human-modified and disturbed habitats. Rarely in rainforest between 130-650m altitude ^[1].
• Colony Type: Colony structure unconfirmed. Based on typical Camponotus patterns, likely single-queen colonies.
• Size & Growth:
  • Queen:{.size-link} Size data unavailable, inferred from Camponotus genus patterns (~10-14mm)
  • Worker:{.size-link} Size data unavailable, inferred from Camponotus genus patterns (minor ~5-8mm, major ~8-12mm)
  • Colony: Up to several hundred workers, inferred from typical Camponotus colony sizes
  • Growth: Moderate, inferred from typical Camponotus development
  • Development: Approximately 6-8 weeks at optimal temperature, inferred from typical Camponotus development (Development time inferred from genus patterns. Warmer temperatures within range accelerate development.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. As a tropical Malagasy species, they need warmth. A heating cable on one side of the nest creates a gradient allowing ants to self-regulate ^[1].
  • Humidity: Moderate humidity around 60-80%. Their arboreal nesting in dead twigs suggests they tolerate drier conditions than ground-nesting ants. Provide a water tube but allow the nest to dry partially between rehydration.
  • Diapause: No true diapause required. As a tropical species from Madagascar, they do not need hibernation. Keep temperatures stable year-round.
  • Nesting: Arboreal nesting species, they naturally nest in dead twigs and branches above ground. In captivity, they do well in Y-tong (AAC) nests, plaster nests with narrow chambers, or test tube setups. Avoid fully naturalistic setups with soil as they prefer dry, elevated nesting sites. The nest should have chambers scaled to their size with some vertical orientation.
• Behavior: Generally calm and non-aggressive for a Camponotus species. They are arboreal foragers, so they spend more time climbing than ground-dwelling ants. Workers are moderately active and will explore vertical spaces. Major workers can defend the colony but rarely show aggression toward keepers. Escape risk is moderate, use standard Camponotus escape prevention. They are not known for being particularly defensive or for having painful stings.
• Common Issues: arboreal nature means they may climb out of horizontal formicaria, use vertical or Y-tong setups instead., tropical species are sensitive to temperature drops below 20°C, keep warm., colonies may be slow to establish initially, be patient during founding., wild-caught colonies may carry parasites, quarantine and observe new colonies., dry twig nesting means they prefer drier conditions than many ants, avoid over-humidifying the nest.

Housing and Nest Setup

Camponotus edmondi is an arboreal species that naturally nests in dead twigs and branches above ground. This is important for captive care, they do not need soil or ground-level nesting like many other ants. The best housing options are Y-tong (AAC) nests, plaster nests with narrow chambers, or test tube setups. Because they naturally live in twigs, they do well in relatively dry conditions. Avoid fully naturalistic setups with deep soil substrates, these ants prefer to stay elevated. If you use a formicarium, ensure there are climbing surfaces and vertical spaces. A test tube with a cotton plug and water reservoir works well for founding colonies. As the colony grows, you can move to a small Y-tong or plaster nest with chambers sized to the worker count ^[1].

Feeding and Diet

Like most Camponotus species, C. edmondi is omnivorous. They accept sugar sources (honey water, sugar water, ripe fruit) and protein foods (insects, mealworms, crickets). Feed protein 2-3 times per week and keep a sugar source available at all times. As an arboreal forager, they may prefer to hunt or collect food at elevated positions in the outworld. Remove uneaten prey after 24-48 hours to prevent mold. Fresh killed insects are generally better accepted than dried ones. They are not specialized predators, so standard ant feeding protocols work well ^[1].

Temperature and Seasonal Care

Being a tropical species from Madagascar, Camponotus edmondi needs warm conditions year-round. Keep the nest area at 22-26°C. A heating cable placed on top of the nest can help maintain warmth. Room temperature may be sufficient if your home stays in this range. Unlike temperate species, they do not require hibernation or diapause. Temperature drops below 20°C can stress colonies and slow development. Avoid placing the nest near air conditioning vents or drafty windows. Stable, warm conditions year-round will support the best colony growth ^[1].

Colony Development and Growth

Camponotus edmondi follows typical carpenter ant development patterns. The queen seals herself in a chamber and raises the first workers (nanitics) entirely on her own energy reserves. First workers are typically smaller than mature workers. After the nanitics emerge, the queen continues laying eggs while workers take over foraging and brood care. Colony growth is moderate, expect approximately 6-8 weeks from egg to first worker at optimal temperature, then several months to reach 20-30 workers. A mature colony may reach several hundred workers over 2-3 years. Major workers (soldiers) typically appear as the colony grows larger. Be patient during the founding phase, arboreal species can be slower to establish than ground-nesting ants ^[1].

Behavior and Handling

This species is generally calm and manageable. Workers are moderately active and will explore their outworld, especially climbing on any vertical surfaces provided. They are not particularly defensive and major workers are more for show than actual combat. They can bite but rarely do so. Because they are arboreal, they are good climbers, ensure your outworld has barriers or a secure lid. They do not produce the strong formic acid smell that some ants do. When observing your colony, you may see workers carrying brood to different parts of the nest, this is normal. They are not known for aggressive swarming or territorial behavior outside their nest. ^[1]
