Formica cunicularia

Formica cunicularia – The Rusty Chest Ant

Formica cunicularia, also known as the Rusty Chest Ant, is a species of ant that is commonly found in various parts of the world. These ants are known for their distinctive rusty chest color and dark gray belly and head. They belong to the monogyny colony type, meaning that each colony consists of a single queen. The colony size can reach up to 10,000 worker ants.

Size and Appearance

The Queen of Formica cunicularia measures between 8-11mm in length, while the workers are typically smaller, ranging from 4-6mm. The ants have a unique coloration with a rusty chest and a dark gray belly and head, making them easily identifiable.

Nutrition

Formica cunicularia ants have a diverse diet. They primarily feed on food insects, including cockroaches and crickets. They are also known to consume syrup made from a mixture of water and honey, with a ratio of 4:1 to 3:1. In addition, they feed on fruits, vegetables, jelly, and even cooked chicken without salt.

Environmental Needs

Humidity is an essential factor for the well-being of Formica cunicularia ants. They thrive in environments with specific humidity levels. The arena, where they typically forage for food, should maintain a humidity level between 30-50%. In contrast, the nest requires a slightly higher humidity level, ranging from 50-60%.

Temperature is another crucial aspect of their habitat. The arena should have a temperature range of 22-28°C, while the optimal temperature for their nest is slightly lower, ranging from 21-24°C.

Special Traits and Behavior

Formica cunicularia ants have a unique behavior of collecting honeydew from aphid colonies. They are known to “farm” aphids, protecting them from predators and receiving a sugary substance called honeydew in return.

Recommended Nests for Breeding

There are several types of nests that are suitable for breeding Formica cunicularia ants. These include acrylic nests, gypsum nests, aerated concrete nests, earth nests, and cork nests. These nests provide the ants with a suitable environment to build their colonies and ensure their overall well-being.

Overall, Formica cunicularia, or the Rusty Chest Ant, is an intriguing species of ant with its distinctive appearance and unique behaviors. They have specific environmental needs and a diverse diet, making them a fascinating species to observe and study in their natural habitats.
