Camponotus excisus

Quick Summary

• Difficulty: Medium
• Origin & Habitat: Neotropical region, Mexico to Paraguay, with strong presence in Colombia, Brazil, Costa Rica, Panama, and surrounding countries. Found in tropical forests at elevations up to 980m, nesting in empty stems in trees ^[1][2][3].
• Colony Type: Unknown, no specific data on colony structure. Most Camponotus are monogyne, but this is not confirmed for this species.
• Size & Growth:
  • Queen: size unknown, inferred from Camponotus genus (~8-12 mm)
  • Worker: 3.3-4 mm ^[4][1]
  • Colony: Unknown, no colony size estimates available. Based on related Myrmobrachys species, possibly up to several hundred workers.
  • Growth: Moderate, inferred from tropical Camponotus growth patterns.
  • Development: Unknown, no specific data. Based on typical tropical Camponotus, development likely around 6-8 weeks at warm temperatures. (Temperature dependency unknown.)
• Antkeeping:
  • Temperature: No specific temperature data. As a tropical species from forest habitats ^[1], they likely need warmth, around 24-28°C. Use a heating cable on one side of the nest to create a gradient.
  • Humidity: Moderate to high, they come from tropical forests. Keep the nest substrate slightly moist but not waterlogged. Provide a water source and a humidity gradient.
  • Diapause: No, as a tropical species, they likely do not require hibernation. Keep temperatures stable year-round.
  • Nesting: Arboreal nesting preference means they do well in Y-tong (AAC) nests, plaster nests, or test tube setups with access to vertical space. They prefer narrow chambers that mimic their natural hollow stem habitat. Provide twigs or small diameter tubes as founding options.
• Behavior: Generally calm and non-aggressive. Workers are small but active foragers. They do not have a functional sting, they spray formic acid as a defense. Their small size (3.3-4mm) means escape prevention is important, they can slip through small gaps. They are arboreal by nature. They accept sugar water and protein sources readily.
• Common Issues: small worker size means escape prevention must be excellent, use fine mesh barriers, tropical species requires consistent warmth, cold temperatures can slow or stop brood development, arboreal nesting means they need vertical space and climbing structures, colonies may be slow to establish initially, patience is needed during founding, wild-caught colonies may carry parasites that can cause colony loss

Nest Preferences and Housing

Camponotus excisus is an arboreal species that naturally nests in hollow twigs, dead branches, and empty plant stems in trees ^[1]. In captivity, they do well in Y-tong (AAC) nests, plaster formicaria, or test tube setups. The key is providing narrow chambers and passages that mimic their natural hollow stem habitat. They prefer some vertical space since they are tree-nesting ants. A test tube setup works well for founding colonies, use a small diameter tube (around 1cm or less) to match the natural stem sizes they would occupy in the wild. Once the colony grows, you can move them to a formicarium with multiple connected chambers. Avoid large, open spaces, they feel more secure in tight, enclosed areas.

Feeding and Diet

No specific dietary data exists for this species. Based on typical Camponotus diet, they are omnivorous. Offer sugar sources such as sugar water, honey, or diluted maple syrup. For protein, provide small insects like fruit flies, small crickets, or mealworms. Offer sugar constantly and protein every 2-3 days. Remove uneaten prey after 24 hours to prevent mold. Their small size means prey items should be appropriately sized.

Temperature and Seasonal Care

As a tropical species from the Neotropics ^[1], Camponotus excisus likely needs warm temperatures to thrive. Aim for 24-28°C, using a heating cable on one side of the nest to create a gradient. They do not require hibernation or diapause, maintain stable tropical temperatures year-round. Avoid temperatures below 20°C for extended periods as this can slow their metabolism and brood development. Room temperature in most homes (22-25°C) is usually suitable, but you may need to add gentle heating during cooler months.

Humidity and Water

Camponotus excisus comes from tropical forests where humidity is moderate to high ^[1]. Keep the nest substrate slightly moist but not waterlogged. A test tube setup with a water reservoir (the standard cotton-ball-in-water method) provides adequate humidity through evaporation. For formicaria, mist the nest occasionally and ensure the substrate has some moisture. They also need a constant water source, a shallow water dish or damp cotton ball. The key is balance: too dry and they desiccate, too wet and you risk mold. Provide a humidity gradient so they can choose their preferred conditions.

Behavior and Colony Dynamics

This is a calm, relatively non-aggressive species. Workers are small (3.3-4mm) but active and will readily explore their environment. They are arboreal by nature, so they climb well and prefer to travel along branches, twigs, and other elevated paths. They do not have a functional sting, they spray formic acid as a defense. Colonies grow at a moderate pace, expect several months from founding to the first workers (nanitics), then steady growth afterward. The colony will likely reach several hundred workers over time. Queens are long-lived, as is typical for Camponotus, so this can be a long-term colony if well cared for. However, much of this is inferred from related species since specific data on Camponotus excisus is limited ^[1][4].
