Breeding and Reproduction
Let’s dive into how you can successfully breed these remarkable tarantulas, from recognizing mating signals to incubating eggs. This crucial process requires patience, dedication, and a solid understanding of their unique needs.
Life Cycle and Mating Habits
The Brazilian white knee tarantula (Acanthostichus fuscifer) undergoes a complex life cycle that spans several years. From egg sac to mature adult, their growth stages are divided into three distinct phases: the juvenile, sub-adult, and adult stages.
During the juvenile stage, which lasts around 6-8 months, the spiderling will molt several times as it grows in size. It’s essential for keepers to provide a suitable environment with adequate humidity, temperature control, and a varied diet to ensure healthy growth. Inadequate care during this critical phase can lead to stunted growth or even death.
As the tarantula reaches its sub-adult stage (around 1-2 years), it will continue to molt and grow. Mating typically occurs within this stage, with males performing elaborate courtship displays to impress potential mates. However, male Brazilian white knee tarantulas have a relatively short lifespan after mating, often dying shortly thereafter due to the energy expenditure of reproduction.
Female tarantulas, on the other hand, can live for up to 15 years or more in captivity, making them a long-term commitment for keepers. With proper care and attention, Brazilian white knee tarantulas can thrive, providing hours of fascination and educational value to enthusiasts.
Raising Tarantulas from Egg Sacs
Raising young Brazilian white knee tarantulas from egg sacs can be an exciting and rewarding experience for breeders. The first step is to provide a suitable environment that mimics their natural habitat.

A secure, escape-proof enclosure with adequate ventilation is essential.
It’s crucial to handle the egg sacs carefully, as they are fragile and can be easily damaged. Once the sling (baby tarantula) emerges from the sac, feed them a diet of pinhead crickets or fruit flies every 7-10 days. As they grow, you can introduce larger prey items such as small crickets or mealworms.
Monitor the slings’ growth and development closely, making sure to provide enough hiding places and visual barriers to help them feel secure. Avoid overcrowding, as this can lead to stress and cannibalism. With proper care and attention, your Brazilian white knee tarantulas will thrive and grow into healthy, adult specimens.
