Camponotus mayri

Camponotus mayri - "Mayr's Sugar ant"

Camponotus mayri is a medium-sized carpenter ant species native to the Afrotropical region, found across southern and eastern Africa including South Africa, Zimbabwe, Mozambique, Kenya, and Tanzania. Workers measure around 5-8mm, with the typical Camponotus body shape featuring a rounded thorax and a distinctively constricted petiole. The species was first described by Forel in 1879 from specimens collected in South Africa's Transvaal region. This ant belongs to the subgenus Orthonotomyrmex and is one of several Camponotus species documented in African grasslands and savanna habitats. The species shows preference for lower altitude grassland environments (lowveld) at elevations around 1000m, where it nests in soil or under stones.

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Afrotropical region, found in southern and eastern Africa including South Africa, Zimbabwe, Mozambique, Kenya, Tanzania, Democratic Republic of Congo, Namibia, and Eswatini. Inhabits lowveld natural grassland habitats at approximately 1074m elevation ^[1][2].
• Colony Type: Single-queen (monogyne) colonies based on typical Camponotus patterns. Colony structure is not directly documented for this species.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 12-15mm based on typical Camponotus queen size ranges
  • Worker: Estimated 5-8mm based on genus patterns
  • Colony: Estimated several hundred workers based on typical Camponotus colony development
  • Growth: Moderate, based on typical Camponotus development patterns
  • Development: Estimated 6-10 weeks based on typical Camponotus development at optimal temperature (Development time is estimated from related Camponotus species. Queens seal themselves in during founding and live off stored fat reserves until first workers emerge.)
• Antkeeping:
  • Temperature: Keep at 24-28°C based on African grassland habitat preferences. Provide a temperature gradient allowing workers to self-regulate. Room temperature within this range is acceptable.
  • Humidity: Moderate humidity around 50-60%. Keep nest substrate slightly moist but not waterlogged. Provide a water source.
  • Diapause: Yes, based on temperate to subtropical origin, colonies benefit from a mild winter rest period (diapause) at 15-18°C for 2-3 months during winter months.
  • Nesting: Use a Y-tong (AAC) nest or test tube setup with compact chambers. Camponotus mayri will accept typical formicarium setups. Provide a small outworld for foraging. Keep nesting area dark and undisturbed.
• Behavior: Typical Camponotus temperament, generally calm and not overly aggressive. Workers are moderately active foragers, primarily hunting for honeydew and small insects. Escape risk is moderate due to medium worker size, standard barrier methods (Fluon on edges) work well. They are not known to be particularly aggressive or sting painfully.
• Common Issues: colonies grow slowly during the first year, beginners may overfeed or disturb the nest prematurely, queen can die during founding if humidity fluctuates too much, keep founding chamber stable, escape prevention should still be used despite moderate size, they can climb smooth surfaces, winter dormancy is important, skipping diapause can weaken colonies over time, wild-caught colonies may have parasites that are difficult to treat in captivity

Nest Preferences and Housing

Camponotus mayri adapts well to common antkeeping setups. A Y-tong (AAC) nest works excellently for this species, providing the dark, compact chambers these ants prefer. Test tube setups are also suitable for founding colonies. The species shows flexibility in nesting materials and will accept acrylic, plaster, or ytong nests. For founding colonies, a simple test tube with a water reservoir connected to a cotton plug provides adequate humidity control. As the colony grows, you can transition to a formicarium with multiple chambers. Keep the nest area relatively dark and avoid frequent disturbances, especially during the founding stage. The outworld should be small initially and expanded as the colony reaches 50+ workers.

Feeding and Diet

Like other Camponotus species, Camponotus mayri is omnivorous with a preference for sugar sources and protein. Offer sugar water (1:1 ratio) or honey as a constant energy source. For protein, provide small insects such as fruit flies, small crickets, or mealworms. Frequency should be 2-3 times per week for protein, with sugar water always available. Workers will consume honeydew if available fromaphids, making them useful in setups where you keep aphid colonies. During founding, the queen does not eat, she relies entirely on stored fat reserves. Once workers emerge, they will begin foraging and can be offered small prey items. Remove uneaten prey after 24 hours to prevent mold.

Temperature and Seasonal Care

Maintain temperatures between 24-28°C for optimal colony development. This species originates from African grasslands where temperatures are warm year-round. A heating cable or mat on one side of the nest can create a temperature gradient, allowing workers to regulate their own temperature by moving between warmer and cooler areas. Place heating on top of the nest to avoid excessive drying. During winter months (roughly November-February in the Northern Hemisphere), reduce temperature to 15-18°C for a diapause period. This rest period helps synchronize colony cycles and promotes healthier development. Do not feed during diapause but maintain light humidity. Room temperature within the 24-28°C range is acceptable without additional heating. ^[2][1]

Behavior and Colony Dynamics

Camponotus mayri exhibits typical carpenter ant behavior, calm temperament with moderate activity levels. Workers are primarily nocturnal or crepuscular foragers, though they will forage during the day if food is available. The colony starts slowly during founding, with the queen laying eggs and raising the first brood alone. These first workers (nanitics) are typically smaller than normal workers. As the colony grows, you'll see distinct size variations between minor and major workers. Major workers (soldiers) have larger heads and are tasked with seed processing and colony defense. The species does not sting painfully but may bite if threatened. Escape prevention using Fluon on container edges is recommended, though not as critical as with tiny species.
