Camponotus solon

Camponotus solon

Camponotus solon is a large carpenter ant species native to tropical Africa, found across countries including Angola, Benin, Democratic Republic of Congo, Gambia, Guinea, Ivory Coast, Kenya, Nigeria, and Senegal. Originally described as a subspecies of Camponotus maculatus, this species belongs to the subgenus Tanaemyrmex and is known for its arboreal nesting habits in forest-savanna mosaics. Workers are typically robust with a dark coloration, and queens can reach impressive sizes typical of Camponotus species. This ant competes with other canopy-dwelling species like Oecophylla longinoda, indicating strong territorial behavior in their natural habitat ^[1].

What makes C. solon interesting for antkeepers is its arboreal nature, unlike many carpenter ants that nest in dead wood on the ground, this species is frequently found in the forest canopy. This influences their humidity requirements and makes them somewhat more moisture-tolerant than typical dry-wood nesting Camponotus. They are active foragers that readily exploit sugar sources and protein, making them relatively straightforward to feed in captivity.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Tropical Africa, found across West and Central African regions including Angola, Benin, DRC, Gambia, Guinea, Ivory Coast, Kenya, Nigeria, and Senegal. Inhabits forest-savanna mosaic environments where they nest arboreally in the canopy ^[1][2].
• Colony Type: Monogyne, single queen colonies typical for this species. Like most Camponotus, colonies start with one claustral queen who seals herself in to raise the first brood alone.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: 15-20mm estimated based on typical Camponotus size range
  • Worker: 6-12mm (polymorphic, major and minor workers)
  • Colony: Several thousand workers at maturity, typical for large Camponotus species
  • Growth: Moderate, Camponotus colonies grow steadily but not as rapidly as smaller species
  • Development: 6-8 weeks at optimal temperature, typical for Camponotus genus (Development is temperature-dependent, warmer conditions within safe range speed development. First workers (nanitics) are smaller than mature workers.)
• Antkeeping:
  • Temperature: Keep nest area at 24-28°C. A heating cable on one side creates a gentle gradient allowing ants to self-regulate. Avoid temperatures above 32°C as this can stress the colony ^[1].
  • Humidity: Moderate to high, these arboreal ants prefer conditions closer to forest floor humidity rather than dry wood nesting. Keep nest substrate slightly moist but not waterlogged, with some drier areas available.
  • Diapause: No, as a tropical species, C. solon does not require hibernation. Maintain warm conditions year-round. A slight reduction in temperature during cooler months (down to around 22°C) may be appropriate but is not required.
  • Nesting: Y-tong (AAC) nests or plaster nests work well. Their arboreal nature means they tolerate slightly higher humidity than typical dry-wood Camponotus. Provide a water test tube for humidity. Naturalistic setups with cork bark or wood pieces are also suitable.
• Behavior: Generally calm and less aggressive than some Camponotus species. Workers are robust and can deliver a mild bite if threatened, but they are not particularly defensive. They are active foragers that readily search for food. Escape prevention should be moderate, while not the smallest ants, they can still squeeze through small gaps if not properly contained. They accept a wide variety of foods and are not picky eaters.
• Common Issues: tropical species requires year-round warmth, cold drafts can weaken or kill colonies, arboreal nature means they need slightly higher humidity than typical dry-wood Camponotus, colonies grow large over time and will need expanding housing as they mature, wild-caught colonies may harbor parasites or diseases that can devastate captive colonies, competition with Oecophylla in the wild suggests they can be territorial, provide adequate space to reduce stress

Housing and Nest Setup

Camponotus solon does well in Y-tong (AAC) nests, plaster nests, or naturalistic setups. Their arboreal nature means they tolerate slightly more moisture than typical dry-wood nesting Camponotus, so a plaster nest with a water reservoir works well. Provide a test tube water source attached to the outworld. For the outworld, use a standard foraging area with a secure lid. Escape prevention should be moderate, these are large ants but can still find small gaps. Apply fluon to the rim of the foraging area if needed. A layer of substrate in the outworld is optional but helps with humidity. Keep the nest area darker as ants prefer to nest in sheltered locations. ^[1]

Feeding and Diet

Like most Camponotus, C. solon accepts a varied diet. Provide a constant sugar source, sugar water, honey, or diluted honey water works well. For protein, offer insects such as mealworms, crickets, fruit flies, or other small arthropods. Feed protein 2-3 times per week, adjusting based on colony size. Remove uneaten prey after 24-48 hours to prevent mold. These ants are active foragers and will readily search for food, so placing food in the outworld is usually sufficient. Colonies with hundreds of workers can consume significant amounts of protein, so be prepared to increase feeding as the colony grows.

Temperature and Seasonal Care

Maintain nest temperatures between 24-28°C year-round. As a tropical African species, C. solon does not require hibernation or diapause. A slight seasonal temperature fluctuation (dropping to around 22°C in winter months) is acceptable but not necessary. Avoid placing the nest near air conditioning vents or drafty windows. If your room temperature falls below 24°C, use a heating cable on one side of the nest to maintain warmth. Place the heating cable on top of the nest material, not underneath, to avoid excessive drying. Monitor colony activity, workers should be actively foraging, if they cluster in one area, they may be seeking heat. ^[1]

Colony Development and Growth

A newly mated queen will seal herself in a claustral chamber and lay eggs after 1-2 weeks. She feeds the first brood from her stored fat reserves and metabolic byproducts. First workers (nanitics) emerge after 6-8 weeks and are smaller than mature workers. Once nanitics emerge, the queen stops caring for the brood, workers take over all colony tasks. Growth is moderate, expect the colony to reach 50-100 workers in the first year under good conditions. Mature colonies can reach several thousand workers over several years. The colony will become increasingly polymorphic as it grows, with larger major workers developing to handle defensive and seed-processing tasks.

Behavior and Temperament

Camponotus solon is generally calm and not particularly aggressive. Workers may deliver a mild bite if the colony is threatened, but they are not defensive like some ant species. They are active foragers and will readily explore their outworld in search of food. Their arboreal nature means they are comfortable climbing and can often be found on vertical surfaces. In the wild, they compete with Oecophylla longinoda, suggesting they can be territorial, provide adequate space in captivity to reduce potential stress between colony members. These ants communicate through chemical signals and will form trails to food sources once discovered. ^[1]
