Care Guide
Crematogaster depilis, commonly known as the acrobat ant, earns its name from the distinctive habit of raising its heart-shaped gaster over its head when disturbed — a defensive posture that is as charming as it is functional. The queen, measuring 5–7 mm, is noticeably larger than the workers, which range from 2.5 to 3.5 mm and display a slender, polished appearance. Colonies can grow to several thousand individuals, and while they are not truly polymorphic, the size variation between queen and workers is enough to appreciate the social structure of this species.
One of the most fascinating aspects of Crematogaster depilis is its nesting flexibility. In the wild, they colonize dead wood, under bark, or even in cavities in soil, and they are known to be aggressive defenders of their territory. Their diet is varied and opportunistic: they require a steady supply of insects for protein, alongside sugar water or honeydew to fuel their energetic foraging. These ants are rapid recruiters and will quickly mob food sources, making feeding sessions a lively spectacle. A small amount of protein is essential for brood development, and they will readily accept fruit flies, mealworms, or small crickets.
Care difficulty
Keeping Crematogaster depilis is best suited for intermediate keepers. While they are not overly demanding, their sensitivity to moisture and temperature requires attention. The colony thrives in a warm environment between 24 and 30°C, with humidity levels around 40–60%. They do not require hibernation, which simplifies year-round care. The main challenge lies in preventing escapes — these ants are excellent climbers and can squeeze through tiny gaps, so a secure barrier such as fluon or oil is essential around the outworld.
Housing
A formicarium with multiple chambers works well, as Crematogaster depilis appreciates having separate spaces for brood, food storage, and waste. A hybrid setup with a plaster or acrylic nest connected to a spacious outworld is ideal. The nest area should be kept moderately moist — not wet — to support larval development. These ants are not heavy burrowers, so a substrate like sand or clay can be offered for decoration, but they will generally nest in pre-formed chambers. Provide a heat source, such as a heat cable, to maintain the preferred temperature gradient. Good ventilation is also important to prevent mold, especially given their fondness for moist conditions.
First days after purchase
Upon receiving your Crematogaster depilis colony, place the formicarium in a quiet, dimly lit location and allow the ants to settle for at least 24 hours. Resist the urge to open the nest or handle the queen. Offer a small drop of sugar water and a tiny piece of insect protein near the nest entrance. Observe their behavior: if they begin exploring and feeding, they have acclimated. Over the first week, maintain stable temperature and humidity, and avoid vibrations. Once the colony accepts its new home, you will be rewarded with an active, acrobatic display that makes every feeding time a joy.
