Care Guide
The Camponotus aethiops, often called the black ghost ant by hobbyists, is a visually striking carpenter ant species native to southern Europe. The queen is a sleek, dark beauty measuring 12–14 mm, while workers display a modest size range from 6 to 12 mm. Although not as dramatically polymorphic as some *Camponotus* species, the larger workers act as formidable defenders and foragers, while smaller workers handle brood care and nest maintenance. The entire colony shares a deep, glossy black coloration with subtle reddish-brown legs, giving them an elegant appearance under good lighting.
One of the most distinctive traits of *Camponotus aethiops* is their crepuscular to nocturnal foraging rhythm. In nature, they emerge at dusk and during the night to search for insects, honeydew from aphids, and sweet liquids. Their diet in captivity should reflect this: a steady supply of protein-rich insects (such as fruit flies, crickets, or mealworms) alongside sugar water or honey water. They also appreciate occasional honeydew substitutes. Unlike seed‑based species, you’ll need to maintain a consistent source of live or frozen protein for healthy brood development. Because of their size and activity level, they can become quite bold once established, but they remain relatively calm and non‑aggressive compared to some other *Camponotus*.
Care difficulty
Keeping *Camponotus aethiops* is best suited for intermediate ant keepers. The claustral founding phase is straightforward: the queen seals herself in a dark, humid chamber and does not feed until the first workers arrive. However, the colony’s need for a proper autumn diapause (hibernation at around 12 °C for two to three months) makes them more demanding than beginner‑friendly species. Missing hibernation can lead to reduced queen longevity and stunted growth. Additionally, their nocturnal nature means they may seem inactive during the day, which can worry new keepers.
Housing
A formicarium with moderate moisture is ideal. Keep humidity levels between 50 % and 70 %, with one corner of the nest slightly damper to allow the queen and larvae to regulate according to their needs. Temperature should range from 22 °C to 28 °C during the active season, lowering gradually in autumn. Because workers grow large, the nest tunnels must be wide enough for them to turn around comfortably. A test tube setup works well for founding, but once the colony numbers over thirty workers, a small plaster or acrylic nest with a connected outworld becomes necessary. Provide a heat cable or mat on one side to create a thermal gradient. The outworld should have fine sand or a non‑toxic substrate, plus a water source such as a small test tube with cotton.
First days after purchase
When your *Camponotus aethiops* colony arrives, place the entire container into a quiet, darkened area at room temperature. Let them sit undisturbed for at least 24 hours to settle. After that, check that the queen is alive and that workers have access to a drop of sugar water and a few tiny pieces of insect. Resist the urge to open the setup frequently; these ants can be sensitive to vibrations during the first weeks. Observe feeding activity in the evenings using a red light or dim flashlight. A healthy queen should begin laying eggs within a few days if conditions are right. Once the first nanitics appear, the colony will gain confidence and become more visible over time.
