Physical Attributes

Acanthoscurria Geniculata, also known as the Brazilian whiteknee tarantula, is a large and robust species with a leg span that can reach up to 8 inches. They have a striking black body with white stripes on their legs, giving them a unique appearance.

Behavior

Acanthoscurria Geniculata is known for its docile nature, making it a popular choice for beginner tarantula keepers. They are generally calm and easy to handle, although they can become defensive if provoked. On the other hand, Poecilotheria Metallica is a more skittish and fast-moving species. They are known for their speed and agility, making them a challenging species to handle for inexperienced keepers.

Feeding Habits

Both Acanthoscurria Geniculata and Poecilotheria Metallica are carnivorous and feed primarily on insects. Acanthoscurria Geniculata is a voracious eater and will readily consume a variety of prey items, including crickets, roaches, and mealworms. Poecilotheria Metallica is also a good eater, but they may be more selective in their food choices. Some individuals may prefer larger prey items, such as adult crickets or even small mice.

Habitat Requirements

Acanthoscurria Geniculata is a terrestrial species that requires a spacious enclosure with plenty of floor space to roam. They prefer a substrate that allows for burrowing, such as coconut fiber or peat moss. Additionally, they require a water dish for hydration and humidity control. Poecilotheria Metallica, on the other hand, is an arboreal species that requires a taller enclosure with vertical space for climbing. They prefer a substrate that allows for webbing, such as cork bark or sphagnum moss. Additionally, they require branches or other climbing structures in their enclosure.

Temperature and Humidity

Both Acanthoscurria Geniculata and Poecilotheria Metallica require similar temperature and humidity ranges to thrive. They both do well in temperatures ranging from 75-85 degrees Fahrenheit and humidity levels of around 60-70%. It is important to provide a temperature gradient in their enclosure, with a warmer side for basking and a cooler side for thermoregulation. Additionally, misting their enclosure regularly can help maintain proper humidity levels for both species.

Reproduction

Reproduction in Acanthoscurria Geniculata and Poecilotheria Metallica follows a similar process. Mating typically occurs when the male performs a courtship dance to attract the female. If successful, the female will produce an egg sac containing hundreds of eggs. The female will guard the egg sac until the spiderlings hatch, at which point they will disperse on their own. It is important to provide the female with a suitable egg-laying site and to monitor the egg sac closely to ensure successful hatching.
