Origins and Species Facts:

Camponotus, commonly known as carpenter ants, are one of the most widespread and recognizable ant genera, found in various regions across the world, particularly in temperate forests. These ants are known for their large size and their unique nesting habits, which often involve excavating wood to create their nests. Despite this, carpenter ants do not eat wood; instead, they create galleries and tunnels within it to establish their colonies.

There are over 1,000 species within the Camponotus genus, each with its own specific habitat preferences. Some of the most well-known species include Camponotus pennsylvanicus (the black carpenter ant) and Camponotus herculeanus. These ants are polymorphic, meaning they have workers of different sizes, which can include major workers, minor workers, and intermediates, each with distinct roles within the colony.

Carpenter ants are nocturnal and are often seen foraging at night. They have a diet that includes both sugars and proteins, and they are known for tending aphids to harvest honeydew. Due to their wood-excavating behavior, they are considered a structural pest when they infest homes or buildings, but in the wild, they play an essential role in the ecosystem by aiding in the decomposition of dead wood.

Founding:

To ensure the successful founding of a Camponotus queen, it is crucial to minimize stress. Avoid excess vibrations or movement, as this can cause the queen unnecessary stress. Camponotus queens are fully claustral, meaning they do not need to leave their founding chamber for food until the first generation of workers, known as nanitics, are born. The queen relies on her energy reserves to produce this initial brood.

During this stage, it's best to leave the queen undisturbed and allow her to focus on brood development. This process can take several weeks to a couple of months, depending on the species and environmental conditions.

Starter Colony:

Once the first workers emerge, it is time to start feeding the colony. The diet should consist of sugar water (a mixture of 1 part sugar to 3 parts water) and insect protein. Suitable protein sources include nymph roaches, fruit flies, or mealworms. Fruit flies are a favorite for most species.

Carpenter ants have a preference for sugary foods, so it’s important to regularly provide sugar water. The workers will also appreciate small pieces of insect protein, which are essential for brood development. Start with small amounts of food, and gradually increase the quantity as the colony grows and their needs expand.

Enclosure:

For the early stages of colony development, a "tub and tube" setup is recommended. This setup involves placing the test tube nest inside a larger container (the tub) with a fluon barrier applied inside to prevent escapes. Once the workers have emerged, you can transfer them to the tub, which should have a thin layer of sand at the bottom to mimic their natural environment.

After transferring, you can remove the cotton ball blocking the test tube entrance to allow the ants to explore their new space.

Feeding:

Feeding Camponotus ants requires a bit of attention to detail. Place a small tray or a piece of foil inside the enclosure for feeding. Add one to two drops of sugar water, spread out to prevent the ants from drowning. Additionally, provide small pieces of insect protein, which the workers will carry back to the nest to feed the queen and larvae. If you have one, a byFormica Nectar Feeder can be placed inside the enclosure for the ants to freely consume sugars from.

Adjust the feeding schedule and quantity based on the colony's consumption. If you notice food is consistently left uneaten, reduce the amount. If the ants consume everything quickly, consider increasing the portions.

Heating:

Maintaining an optimal temperature is key to the colony's growth. A Zoomed heating cable is recommended, with a target temperature range of 80-85°F for most Camponotus species. Place the heating cable under the portion of the test tube without water (first inch or so), which allows the ants to regulate their own temperature by moving closer to or further away from the heat source.

When using the tub and tube setup, position the heating cable underneath the enclosure aligned with the front of the test tube to create a warm spot within the tub.

Nests for Expansion:

As the colony grows and reaches approximately 30-50 workers, you may consider moving them into a larger nest. The new nest should be spacious enough for the colony to occupy at least a quarter of the available space.

Quality nests designed specifically for Camponotus colonies are available from suppliers like Tarheel Ants. These nests often feature moisture control systems and various chambers that mimic the natural nesting sites of carpenter ants.

Diapause:

To replicate the natural growth cycle of Camponotus ants, it is important to subject them to a period of diapause, which is a form of dormancy that occurs during winter. This three-month period involves lowering the temperature in the enclosure to 55-65°F. During diapause, the ants will enter a state of reduced activity, and no feeding is required. The best way to achieve these temperatures is with a wine fridge.

However, it is crucial to ensure that the ants still have access to water during this time. Properly preparing the colony for diapause will help maintain their health and promote natural growth cycles. Note that it is normal for some workers to die during this process.
