Life Cycle and Reproduction

Egg Stage

During the egg stage, the queen Brachymyrmex depilis lays small, white, oval-shaped eggs. These eggs are tended to by the queen and other worker ants, who keep them clean and protect them from predators. The eggs typically hatch within two to three weeks, depending on temperature and humidity levels. Once the eggs hatch, they become larvae and are fed by the worker ants. The egg stage is a crucial part of the Brachymyrmex depilis life cycle, as it is the beginning of the ant’s development and growth.

Larval Stage

During the larval stage, Brachymyrmex depilis undergoes a complete metamorphosis. The larvae are small, white, and legless, and they rely on the workers to feed them. The workers provide the larvae with a protein-rich secretion that they produce from their salivary glands. As the larvae grow, they molt several times, shedding their skin and growing larger with each molt. The length of the larval stage varies depending on environmental conditions such as temperature and food availability. Once the larvae have completed their development, they pupate and eventually emerge as adult ants.

Pupal Stage

During the pupal stage, the Brachymyrmex depilis undergoes metamorphosis and transforms into an adult ant. This stage typically lasts for about two weeks, during which the pupa is enclosed in a cocoon-like structure. The pupa is immobile and vulnerable, and it relies on the worker ants to provide it with food and protection. Once the pupal stage is complete, the adult ant emerges from the cocoon and begins its life as a worker ant. The pupal stage is a critical period in the life cycle of the Brachymyrmex depilis, and any disruptions or disturbances during this time can have a significant impact on the colony’s overall health and success.

Adult Stage

During the adult stage, Brachymyrmex depilis ants are typically about 2.5 to 3.0 mm in length and have a dark brown to black coloration. They have a distinct waist and a pair of antennae that are 12-segmented. The workers are responsible for foraging, caring for the brood, and defending the colony. The queen is larger than the workers and is responsible for laying eggs. The males are winged and their sole purpose is to mate with the queen. The lifespan of an adult Brachymyrmex depilis ant is around 6 months.
