Camponotus brullei

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Canary Islands (Lanzarote and Fuerteventura) and coastal Morocco (from Essaouira to TanTan, Agadir, Ademine). This species thrives in warm, dry to semi-arid environments including volcanic craters, coastline areas, and Argan forest ecosystems. They nest in the ground and are adapted to Mediterranean-type climates with hot, dry summers and mild winters ^[1][3][2][4].
• Colony Type: Colony type is unconfirmed. Like most Camponotus species, colonies likely have one founding queen, but specific data for this species is unavailable.
• Size & Growth:
  • Queen: ~12-20mm, inferred from Camponotus genus patterns
  • Worker: ~6-15mm, inferred from Camponotus genus patterns (polymorphic, major and minor workers)
  • Colony: Colony size data unavailable for this species
  • Growth: Moderate, Camponotus species typically take several months to establish first workers from founding
  • Development: Development timeline is unconfirmed for this species. Based on typical Camponotus patterns, expect 6-12 weeks at warm temperatures (24-28°C). (Development is temperature-dependent. Nanitics (first workers) are smaller than mature workers.)
• Antkeeping:
  • Temperature: 24-30°C during active season. They tolerate warmer conditions given their Canary Islands origin. A gradient of 24-28°C in the nest area is ideal, with access to warmer areas for foraging activity ^[1].
  • Humidity: Low to moderate, 40-60%. These ants come from arid to semi-arid regions, so avoid excessive moisture. Keep nest substrate slightly moist but allow drying periods between waterings. Provide a water source separately rather than over-humidifying ^[1][3].
  • Diapause: Yes, provide a winter rest period of 8-12 weeks at 10-15°C. This mimics their natural seasonal cycle in the Canary Islands where temperatures drop in winter months. Reduce feeding during this period.
  • Nesting: Ground-nesting species that does well in Y-tong (AAC), plaster, or naturalistic setups with soil/sand substrate. Provide a nest chamber with moderate humidity and avoid overly damp conditions.
• Behavior: Generally docile and non-aggressive toward keepers. Like most Camponotus, they are primarily nocturnal or crepuscular foragers, though they may show activity during the day. Workers are polymorphic, larger major workers handle seed processing and defense while smaller minors forage. This species lacks a functional sting. As with other Formicinae, they defend by biting and spraying formic acid from their acidopore. Escape risk is moderate, use standard barrier methods (Fluon on test tube rims, fine mesh on outworlds).
• Common Issues: colonies often fail if kept too humid, these are dry-adapted ants from arid Canary Islands, test tube setups can flood if water reservoirs are overfilled, use small water reservoirs, slow founding phase causes beginners to over-interfere, queens need darkness and minimal disturbance for several weeks, winter die-offs occur if diapause is not provided or if temperatures fluctuate erratically, wild-caught colonies may contain parasites that can devastate captive colonies, quarantine and observe new colonies

Housing and Nest Setup

Camponotus brullei adapts well to various captive setups. Y-tong (AAC) nests work excellently, the smooth interior prevents escape and allows easy observation. Plaster nests with sand/soil mix also suit this ground-nesting species. Test tube setups are ideal for founding colonies, use a small water reservoir to prevent flooding. For outworlds, any standard foraging area works, though these ants are not prolific climbers so vertical space matters less than floor space. Provide a shallow water dish and a small piece of bark or cork as a foraging platform. Because they come from arid regions, ensure ventilation prevents moisture buildup while still maintaining some humidity in the nest chamber ^[1].

Feeding and Diet

Like all Camponotus, this species is omnivorous with a preference for protein sources. Feed a varied diet: sugar water or honey (always available), protein sources like mealworms, crickets, or other insects several times weekly. They will accept small seeds and fruit pieces. In the wild, they forage on the ground for insects and honeydew from aphids. For captive colonies, offer a drop of honey or sugar water every few days and remove uneaten prey after 24 hours to prevent mold. Major workers can handle larger prey items while minors may struggle with anything larger than their head width. Adjust feeding frequency based on colony size, larger colonies consume more but can go longer between feedings ^[3].

Temperature and Seasonal Care

Maintain nest temperatures between 24-28°C year-round during the active season. These ants tolerate heat well given their Canary Islands origin, occasional spikes to 30°C are generally tolerated. Provide a temperature gradient so ants can self-regulate. During winter, gradually reduce temperature to 10-15°C for an 8-12 week diapause period. This rest period is essential for colony health and triggers reproductive cycles. Do not feed during deep diapause but provide a water source. Avoid sudden temperature changes, gradual transitions prevent stress. Room temperature is acceptable for short periods but will slow development and activity ^[1].

Colony Founding and Development

Founding behavior is unconfirmed for this species. Based on typical Camponotus patterns, the queen will likely seal herself into a small chamber and not emerge until her first workers arrive. This typically takes several weeks at optimal temperature. Do not disturb the founding chamber during this period, light and vibration stress queens and can cause them to abandon or eat their brood. Once nanitics emerge, the colony enters a fragile phase. Workers will begin foraging for food. Continue providing sugar water and small protein items. Growth is moderate, expect the colony to reach 50 workers within several months under good conditions. Major workers typically appear once the colony reaches 100+ workers. Patience is key with Camponotus, they are long-lived and colonies can thrive for decades.

Behavior and Temperament

Camponotus brullei is a docile species that rarely shows aggression toward keepers. Workers are primarily nocturnal but will forage during daylight if food is available. They are ground-foragers rather than climbers, so your outworld setup should focus on horizontal space. Major workers serve as defenders and seed processors while minors handle general foraging. They communicate using chemical trails, you may notice workers following the same paths to food sources. Unlike some aggressive ant species, they do not form raiding columns or exhibit territorial behavior beyond their immediate nest area. This species lacks a functional sting. As with other Formicinae, they defend by biting and spraying formic acid from their acidopore. They are moderate escape artists, standard barriers like Fluon on test tube rims and fine mesh on outworlds are sufficient ^[3].
