Origins and Species Facts:

Pheidole is a highly diverse and widespread genus of ants, with over 1,000 species described worldwide. These ants are commonly found in tropical and subtropical regions, but some species also thrive in temperate environments. Pheidole ants are known for their distinctive caste system, which includes both minor workers and larger, more powerful major workers (often referred to as "soldiers").

One of the most fascinating aspects of Pheidole ants is their polymorphism. The minor workers are small and handle the majority of the foraging and brood care, while the major workers possess large heads and strong mandibles, which they use for defense and processing larger food items. Despite their differences in size and function, both castes work together seamlessly to ensure the success of the colony.

Pheidole ants are opportunistic foragers, feeding on a wide variety of food sources, including seeds, insect protein, and sugars. Their adaptability and efficient colony structure make them a popular choice among ant keepers.

Founding:

When founding a Pheidole colony, it is crucial to minimize stress for the queen by avoiding unnecessary movement or vibrations. Pheidole queens are fully claustral, meaning they do not need to leave the founding chamber for food until the first generation of workers, or nanitics, is born.

During the founding stage, the queen relies on her stored energy reserves to produce her initial brood. It is important to provide a stable, quiet environment to ensure the successful establishment of the colony. 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, you can begin feeding the colony. Pheidole ants are omnivorous, meaning they will consume a variety of foods, including insect protein, seeds, and sugars. Suitable feeder insects include fruit flies, small crickets, mealworms, and pieces of larger insects. You can also offer seeds, such as dandelion or grass seeds, as a supplementary food source.

In addition to protein and seeds, Pheidole ants benefit from sugar water (a mixture of 1 part sugar to 3 parts water). Providing a balanced diet with both protein and carbohydrates is essential for the growth and health of the colony.

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 thick fluon barrier applied inside to prevent escapes. The tub provides ample space for the ants to forage and store food while keeping them safely contained.

As the colony grows, the workers will begin to explore the enclosure and establish a routine for foraging and feeding. Ensure that the enclosure is secure and that the fluon barrier is regularly maintained to prevent escapes.

Feeding:

Once the colony has a stable population of workers and is in the tub and tube setup, regular feeding is crucial. Provide small pieces of insect protein, seeds, and sugar water inside the enclosure. Adjust the feeding schedule and quantity based on the colony's consumption.

Pheidole ants are efficient foragers, so it is important to monitor their food intake and ensure they have a consistent supply of both protein and carbohydrates. When introducing sugar water, use a pen or another tool to break the surface tension of the drops, or consider using a byFormica feeder to prevent drowning.

Heating:

Maintaining the proper temperature is key to the optimal growth of Pheidole ants. A Zoomed heating cable is recommended, with a target temperature range of 80-90°F depending on the species.

Pairing the cable with a thermostat is the best way to ensure proper temperatures. Place the heating cable under the edge of the test tube where the open end is located, allowing the ants to regulate their temperature by moving closer to or further from the heat source.

When using the tub and tube setup, position the heating cable under the tub, towards the open end of the test tube, to create a temperature gradient. This helps the ants find their preferred microenvironment within the enclosure.

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 provide ample space for the colony to expand and should allow the ants to occupy at least a quarter of the available space.

Quality nests designed specifically for Pheidole colonies are available from suppliers like Tarheel Ants. These nests often feature moisture control systems and various chambers that mimic the natural underground environment of Pheidole ants, allowing them to thrive and continue growing.
