Camponotus sicheli

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Mediterranean region, specifically coastal areas of Algeria, Tunisia, Spain (including Balearic and Canary Islands), Portugal, Malta, and Gibraltar. They inhabit dry woodland and nest in tree stumps, partially decayed branches, and dry trunks ^[1][4][5][6].
• Colony Type: Colony structure is unconfirmed. Typical for Camponotus genus, but specific data is unavailable.
• Size & Growth:
  • Queen: Size data unavailable, inferred from Camponotus genus patterns (~10-12mm)
  • Worker: 4.5-6.8mm ^[2]
  • Colony: Up to several hundred workers, estimated from genus typical size
  • Growth: Moderate, typical for Camponotus species
  • Development: Estimated 6-10 weeks based on typical Camponotus development at warm temperatures (Development time inferred from genus patterns, actual timing may vary with temperature)
• Antkeeping:
  • Temperature: Keep at 20-26°C. Mediterranean origin means they tolerate warmth but not extreme heat. Room temperature within this range works well, with a slight gradient optional.
  • Humidity: Low to moderate. They naturally nest in dry wood, so avoid overly damp conditions. Provide a water tube but don't saturate the nest area.
  • Diapause: Yes, Mediterranean species benefit from a mild winter rest period around 10-15°C for 2-3 months, mimicking their natural seasonal cycle.
  • Nesting: Y-tong (AAC) nests or plaster nests work well. They prefer dry conditions and will excavate in wood-based formicaria. Avoid overly humid setups.
• Behavior: Generally calm and non-aggressive for a Camponotus species. Workers are active foragers but not particularly defensive. They establish colonies in wood, so provide appropriate nesting material. As Formicinae, they lack a functional sting but can bite and spray formic acid from their acidopore if threatened. Escape risk is moderate, use standard barriers but no special escape prevention needed beyond standard care.
• Common Issues: dry wood nesting means they need specific nest types, standard test tubes may not be ideal for established colonies, colonies may be slow to establish compared to faster-growing genera like Lasius, winter dormancy is important, skipping diapause can weaken colonies over time, dry nesting preference means over-humid conditions can cause problems, limited availability in the antkeeping hobby means founding colonies may be difficult to obtain

Nest Preferences and Housing

Camponotus sicheli has specific nesting requirements that set it apart from many common ant species. In the wild, they nest exclusively in dry wood, specifically in dry trunks, tree stumps, and partially decayed branches ^[4][5][6]. This makes them true carpenter ants that excavate their galleries in wood rather than nesting in soil or under stones.

For captive care, Y-tong (AAC) nests or plaster formicaria with wooden elements work best. The nest should be relatively dry, these ants don't need high humidity like tropical species. A water tube should still be provided for drinking, but the nest chamber itself should stay on the drier side. If using a test tube setup for founding, you can eventually move them to a wooden formicarium once the colony reaches 15-20 workers. Avoid setups that keep the nest constantly damp or humid.

Feeding and Diet

Like other Camponotus species, C. sicheli is omnivorous with a preference for protein-rich foods. Workers will consume sugar water, honey, or diluted syrup as an energy source. For protein, offer small insects like fruit flies, small mealworms, or cricket pieces. In the wild, they forage for honeydew and small invertebrates in their woodland habitat.

Feed protein 2-3 times per week, and keep a sugar source (honey water or sugar water) available at all times. Remove uneaten prey after 24-48 hours to prevent mold. Since they're a moderate-sized ant, portion sizes should match their worker size, not too large that they can't handle it, but substantial enough to feed the colony.

Temperature and Seasonal Care

Being a Mediterranean species, C. sicheli prefers warm but not hot conditions. Aim for 20-26°C in the nest area, with room temperature typically being suitable. They can tolerate brief temperature fluctuations but prefer stability. A heating cable on one side of the nest can create a gentle gradient if your room runs cool.

Winter care is important for this species. They benefit from a mild diapause (winter rest) period of 2-3 months at around 10-15°C. This mimics their natural Mediterranean seasonal cycle and helps maintain colony health. Reduce feeding during this period and keep them in a cooler location (garage, basement, or refrigerator for short periods). Skipping diapause won't kill them immediately but can weaken colonies over time.

Behavior and Colony Dynamics

Camponotus sicheli workers are relatively calm and not particularly aggressive or defensive compared to some other Camponotus species. They establish colonies in wood and expand them through excavation. Workers are active foragers, searching for food both on the ground and in vegetation.

Colony growth is moderate, not as fast as Lasius or as slow as some tropical species. Expect the first workers (nanitics) to emerge 6-10 weeks after founding, with the colony gradually expanding over several months to a year. Maximum colony size is likely several hundred workers based on genus typical patterns. Queens are claustral, they seal themselves in a chamber and raise the first brood alone using stored fat reserves, never leaving to forage during founding.
