Camponotus diversipalpus

Camponotus diversipalpus

Camponotus diversipalpus is a medium-sized carpenter ant species native to Brazil. Workers measure approximately 6-12mm, with queens significantly larger at around 15-18mm. They have the typical Camponotus body shape with a rounded thorax and a smooth, glossy abdomen. This species is found throughout southern and northern Brazil, particularly in the states of Santa Catarina, Rio Grande do Sul, and Pará ^[1].

This is a ground-nesting species that shows flexibility in habitat selection, being found in both native forests and disturbed areas like eucalyptus and pine plantations. It is not a dominant species in its ecosystem, with relatively low collection numbers in studies. Unlike some arboreal Camponotus, this species forages on the ground and nests in soil or under cover rather than in wood ^[2][3].

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Native to Brazil, specifically recorded from Rio Grande do Sul, Santa Catarina, and Pará states. Found in tropical and subtropical environments, including native Atlantic Forest, eucalyptus plantations, pine plantations, and disturbed areas. This is a ground-dwelling species that adapts to various habitat conditions ^[1][2].
• Colony Type: Monogyne (single queen colonies), typical for Camponotus species. Queens are claustral founders, sealing themselves in to raise their first workers alone.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Estimated 15-18mm based on typical Camponotus genus patterns
  • Worker: 6-12mm based on Camponotus worker size range
  • Colony: Likely moderate, estimated 500-2000 workers at maturity based on genus patterns
  • Growth: Moderate, Camponotus species typically take 2-3 months for first workers, then grow steadily
  • Development: Estimated 6-8 weeks at optimal temperature (25-27°C) based on typical Camponotus development (Development time depends on temperature, warmer conditions accelerate growth. First workers (nanitics) are smaller than mature workers.)
• Antkeeping:
  • Temperature: Keep at 22-27°C. Brazilian origin suggests they prefer warm conditions. A temperature gradient allowing workers to choose their preferred spot is ideal
  • Humidity: Moderate humidity around 50-70%. Keep nest substrate slightly moist but allow some drying areas. They adapt to both drier and more humid conditions based on their presence in various Brazilian ecosystems ^[2][3]
  • Diapause: Likely a mild winter slowdown period. As a Brazilian species from subtropical regions, they may not require true hibernation but benefit from cooler temperatures (15-20°C) for 2-3 months during winter months
  • Nesting: Ground-nesting species. In captivity, they do well in Y-tong (AAC) nests, plaster nests, or naturalistic setups with soil. Provide a deep substrate chamber for brood development. They accept test tube setups for founding colonies
• Behavior: Generally calm and non-aggressive compared to some Camponotus species. Workers are moderate foragers that search for protein and sugar sources. They are not known for being particularly defensive but will alert the colony if the nest is threatened. Escape risk is moderate, adult workers are too large for typical escape gaps but claustral queens can squeeze through small openings. Standard escape prevention (Fluon, tight-fitting lids) is recommended.
• Common Issues: queen mortality during founding, claustral queens sometimes fail to establish, especially if disturbed too early, slow initial growth, first workers can take 6-10 weeks, causing impatient keepers to overfeed or check too frequently, mold in nest, occurs if humidity is too high and ventilation is poor, especially in naturalistic setups, queen rejection, introduced queens may be rejected by established colonies if attempting pleometrosis, cold stress, as a Brazilian species, prolonged temperatures below 15°C can weaken or kill colonies

Housing and Nest Setup

Camponotus diversipalpus does well in several nest types. For founding colonies, a simple test tube setup works perfectly, fill a tube one-third with water, plug with cotton, and place the queen in the tube. The queen will seal herself into a chamber at the cotton end and remain there until her first workers emerge. For established colonies, Y-tong (AAC) nests are excellent because they provide proper humidity control and allow you to observe the colony easily. Plaster nests and naturalistic setups with soil also work well for this ground-nesting species. Whatever nest type you choose, ensure the chambers are appropriately sized, too large and the ants may feel exposed, too small and they won't have room to expand. Provide an outworld area for foraging that is easy to clean. Use a substrate barrier like Fluon on the edges of the outworld to prevent escapes.

Feeding and Diet

Like most Camponotus species, C. diversipalpus is omnivorous with a preference for protein foods. Offer protein sources such as mealworms, small crickets, dead insects, or commercially available ant food 2-3 times per week. Remove uneaten prey after 24-48 hours to prevent mold. Sugar is also important, provide a constant source of sugar water (1:3 ratio sugar to water), honey (a small drop every week), or commercial ant nectar. Workers will collect these and feed them to the queen and larvae. Fresh fruit occasionally is also accepted. During the founding stage, the queen does not eat, she survives entirely on her stored fat reserves. Once workers arrive, they will begin foraging and can be fed immediately.

Temperature and Seasonal Care

This Brazilian species thrives at temperatures between 22-27°C. Room temperature in most homes (20-24°C) is acceptable, but warmer conditions (around 25°C) will speed up brood development. You can create a temperature gradient by placing a heating cable or mat under one side of the nest, this allows workers to regulate their own temperature by moving between warm and cool areas. During winter months, a slight temperature reduction to 15-20°C for 2-3 months mimics their natural seasonal cycle and can promote healthier colonies. However, avoid sudden temperature drops or prolonged cold below 15°C, as this species is not cold-hardy. If your room stays warm year-round, a mild winter slowdown is optional but not required.

Colony Development and Growth

After the queen is introduced to her founding chamber, she will seal herself in and lay eggs within a few days. The eggs develop through larval and pupal stages before the first workers (nanitics) emerge. This process typically takes 6-8 weeks at optimal temperature, though it may take longer in cooler conditions. The first workers are smaller than mature workers but will immediately begin caring for the queen and subsequent brood. Colony growth is moderate, expect the population to roughly double every few months under good conditions. A mature colony may contain 500-2000 workers. Growth can be supported by consistent feeding, proper humidity, and maintaining optimal temperature. Avoid disturbing the nest during the founding phase, as stressed queens may abandon or eat their brood.

Behavior and Temperament

Camponotus diversipalpus is generally a calm species that is suitable for antkeeping beginners who have some experience with claustral founding queens. Workers are moderately active and will readily forage for food in the outworld. They are not particularly aggressive and rarely sting, though they may bite if threatened. The colony becomes more alert and defensive as it grows, with workers rapidly responding to nest disturbances. This species shows typical Camponotus foraging behavior, workers search individually for food sources and recruit nestmates through chemical signals when large food items are found. They are primarily ground-foragers, consistent with their ground-nesting habits in the wild ^[2][3].
