Camponotus lateralis

Camponotus lateralis

Camponotus lateralis is a moderately large, polymorphic carpenter ant found across the Mediterranean region and into central Europe, the Caucasus, and northwest Africa. Workers range from 3.9-7.0mm with distinct minor and major castes. The body shows striking color variation, the head and mesosoma range from yellowish-red to dark brown, while the gaster is always dark brown to black, creating a bicolored appearance that serves a crucial survival function. This species is famous for its Batesian mimicry, copying the coloration of the aggressive Crematogaster scutellaris to gain protection without doing the hard work of defending itself. These ants are arboreal foragers that nest primarily in dead wood, including fallen branches and tree stumps, though they also nest under stones and in rock crevices. They feed heavily on honeydew from aphids and scale insects, often climbing into trees and shrubs to tend these sap-sucking insects.

Quick Summary

• Difficulty: Easy
• Origin & Habitat: Mediterranean Europe, from Portugal and Spain east to Turkey, Crimea, and the Caucasus, also northwest Africa. Inhabits warm, dry areas with deciduous trees and shrubs, typically below 500m elevation but found up to 1100m. Nests in dead wood, under stones, and in rock crevices on sunny walls.
• Colony Type: Single-queen colonies (monogyne). Colonies are small to moderate, typically reaching a few hundred workers. Multiple queens have been observed in some nests, but this appears to be occasional rather than typical colony structure.
  • Colony: Monogyne
  • Founding: Claustral
• Size & Growth:
  • Queen: Approximately 8-10mm based on related species and genus patterns ^[1][2]
  • Worker: Minor workers: 3.9-5.5mm, major workers: 5.5-7.0mm ^[1][3]
  • Colony: Typically 50-200 workers, maximum around 700 workers in optimal conditions ^[4]
  • Growth: Moderate, typical for Camponotus, faster in warm conditions
  • Development: 6-10 weeks at optimal temperature (around 24-26°C) based on typical Camponotus development patterns (Development is temperature-dependent, warmer temperatures within acceptable range speed development. First workers (nanitics) are smaller than normal majors.)
• Antkeeping:
  • Temperature: Keep at 22-26°C. This is a warmth-loving Mediterranean species that tolerates high temperatures better than most Camponotus. Room temperature (20-24°C) is acceptable, but warmer conditions support faster growth ^[5]
  • Humidity: Moderate humidity preferred. Provide a water tube for drinking and maintain slight moisture in the nest. These ants naturally inhabit relatively dry Mediterranean environments but need access to water ^[3]
  • Diapause: Not required. As a Mediterranean species, they do not need hibernation. However, a slight winter slowdown at 15-18°C can be beneficial if the colony is healthy, but this is optional rather than necessary.
  • Nesting: Prefers nests in dead wood, fallen branches, stumps, or wood inserts. In captivity, Y-tong nests with wood chambers work well, or test tubes with a wooden dowel insert. They will also accept acrylic nests with wood-themed chambers. Avoid completely artificial setups without any wood element.
• Behavior: Extremely peaceful and submissive. This ant never shows aggression and always flees from confrontations with other species. It survives by mimicking the aggressive Crematogaster scutellaris and following their trails for protection, a classic example of Batesian mimicry. Workers are diurnal and actively forage during daylight hours, especially in the warmer parts of the day. They are excellent climbers and spend significant time in trees and shrubs tending aphids for honeydew. Escape risk is moderate, they are not particularly small but can climb well, so standard barrier methods work fine.
• Common Issues: colonies can fail if stressed by cold, keep warm, wild-caught colonies may carry parasites that affect survival in captivity, small colony size means slower population growth than more prolific species, may be displaced by aggressive invasive ants like Linepithema humile in captivity if housed in shared spaces, nests in wood can dry out, monitor moisture levels

Housing and Nest Setup

Camponotus lateralis does best in nests that mimic their natural wood-dwelling preference. Y-tong (AAC) nests with wood insert or naturalistic setups with cork and dead wood work excellently. You can also use test tubes with a small wooden dowel or popsicle stick as an insert, which satisfies their preference for wood substrates. The colony does not need large spaces, these are modest colony size ants that prefer snug chambers. Provide a water tube connected to the nest for drinking water, as they need constant access. Since they are arboreal foragers, include an outworld with some vertical space or branches where they can forage. Escape prevention is straightforward, they are not tiny and cannot squeeze through gaps like some ant species. Standard fluon barriers on smooth surfaces work well. ^[4][3]

Feeding and Diet

These ants are primarily honeydew feeders, they farm aphids and scale insects for the sweet secretions. In captivity, offer sugar water (1:3 ratio) or honey water constantly. They also readily accept protein foods like small crickets, mealworms, or other insects. Fruit flies and fruit pieces are also taken. Unlike some Camponotus species, C. lateralis is not particularly aggressive and won't take down large prey, keep prey items small and appropriate to worker size. Feed protein 2-3 times per week for growing colonies, and always have sugar water available. They are diurnal foragers, so offer food during daylight hours for best acceptance. ^[5]

Temperature and Seasonal Care

As a Mediterranean species, Camponotus lateralis thrives in warmth. Keep the nest area at 22-26°C, they can tolerate even higher temperatures better than most Camponotus species. A heating cable on one side of the nest creates a nice gradient. Room temperature is acceptable but will result in slower growth. They do not require hibernation, this is a warm-climate species. If you want to simulate seasons, a brief cool period at 15-18°C in winter is optional but not necessary. Avoid temperatures below 15°C for extended periods. High humidity is not required, but they do need access to water. ^[5]

Behavior and Colony Dynamics

This species is famous for its peaceful nature and clever survival strategy. Camponotus lateralis mimics the appearance of Crematogaster scutellaris, the aggressive acrobat ant, and follows their trails to access food sources while avoiding confrontation. When encountering Crematogaster workers, they sidestep and retreat rather than fight. Colonies are small, typically under 200 workers, with a single queen. Major workers have larger heads and serve as defenders, sometimes blocking nest entrances with their heads. Workers are diurnal and very active during warm parts of the day. The colony grows moderately, expect 6-10 months from founding to first significant worker batches. ^[4]

Mimicry and Trail-Following

One of the most fascinating aspects of C. lateralis is its Batesian mimicry. The ant has evolved to resemble Crematogaster scutellaris in coloration, both have a reddish head and dark gaster. This mimicry allows C. lateralis workers to follow Crematogaster trails without being attacked. Studies show about 27% of C. lateralis workers can be found on Crematogaster trails, using their host's pheromone trails to find food. The mimicry is so effective that these two species can share trees without conflict. In your colony, you may observe this behavior if you keep both species or if there are other ants nearby, C. lateralis will try to follow their trails. ^[1]
