Unveiling the Glittering Jewel: A Care Guide for the Phormictopus auratus (Caribbean Bronze)

The Phormictopus auratus, commonly known as the Caribbean Bronze tarantula, is a stunning species highly sought after by collectors and enthusiasts alike. Hailing from the island of Cuba, this tarantula boasts a captivating iridescent bronze sheen across its carapace and legs, making it a true gem of the arachnid world. While their beauty is undeniable, understanding their specific needs is crucial for providing optimal care and ensuring a healthy, thriving spider. This guide aims to provide comprehensive information for keeping your Caribbean Bronze happy and comfortable.

About the Phormictopus auratus:

Scientific Name: Phormictopus auratus

Common Name: Caribbean Bronze, Cuban Bronze

Origin: Cuba

Type: Terrestrial, opportunistic burrower

Size: Up to 7-8 inches leg span

Temperament: Generally skittish and defensive, not recommended for beginners.

Lifespan: Females can live 15+ years, males typically shorter.

Housing:

Enclosure:

Size: A juvenile can start in a 5-gallon enclosure. As they grow, provide at least a 10-gallon enclosure or larger. An enclosure with a floor size of at least twice the spider's diagonal leg span is recommended.

Type: A glass or plastic terrarium with a secure, well-ventilated lid is ideal. Remember, these spiders can climb, so a tight-fitting lid is crucial to prevent escapes.

Substrate:

A deep layer (4-6 inches) of a suitable substrate is essential for burrowing and maintaining humidity. A mixture of peat moss, coconut fiber (coir), and vermiculite or topsoil works well.

Ensure the substrate is free from fertilizers and pesticides.

Hides:

Provide a hide, such as a cork bark slab, half log, or artificial cave, allowing the tarantula to feel secure.

Partial burial of the hide will encourage the spider to expand on it and create a more elaborate burrow.

Water Dish:

A shallow water dish should always be available. Ensure it's shallow enough to prevent drowning, especially for spiderlings.

Consider adding small rocks or pebbles to the dish to further reduce the risk of drowning.

Environment:

Temperature: Maintain a temperature gradient of 75-85°F (24-29°C). This can be achieved using a heat mat placed on one side of the enclosure, not directly underneath.

Avoid overheating, which can be lethal. Use a thermostat to regulate the temperature.

Humidity: Aim for a humidity level of 65-75%. This can be achieved by lightly misting the substrate regularly.

Monitor humidity levels with a hygrometer. Avoid oversaturation, which can lead to mold growth.

Lighting: No special lighting is required. The Caribbean Bronze thrives in ambient room light. Avoid direct sunlight, which can overheat the enclosure.

Feeding:

Diet: Primarily insects such as crickets, roaches, mealworms, and occasionally grasshoppers.

Feeding Frequency:

Spiderlings: 2-3 times a week.

Juveniles: 1-2 times a week.

Adults: Once every 1-2 weeks.

Prey Size: Prey items should be appropriately sized, no larger than the tarantula's carapace.

UnEaten Prey: Remove any uneaten prey after 24 hours to prevent them from stressing the tarantula or causing potential harm.

Pre-Molt: Tarantulas often refuse food when they are in pre-molt. Do not be alarmed if your tarantula stops eating. Ensure a water source is available.

Handling:

Generally Not Recommended: The Caribbean Bronze is known for its defensive temperament and fast movements. Handling is generally discouraged, as it can stress the tarantula and increase the risk of a bite.

If Necessary: If handling is necessary (e.g., for rehousing), use extreme caution. Gently encourage the tarantula into a container.

Defense Mechanisms: Be aware that this tarantula can flick urticating hairs from their abdomen as a defense mechanism. These hairs can cause irritation to the skin and eyes.

Molting:

Tarantulas shed their exoskeletons as they grow. This process is called molting.

Signs of Pre-Molt: Darkening of the abdomen, reduced appetite, lethargy, and increased webbing.

During Molt: Do not disturb the tarantula during molting. Ensure the humidity is adequate to facilitate the shedding process.

Post-Molt: Allow the tarantula several days to harden its new exoskeleton before attempting to feed it.

Potential Problems:

Dehydration: Ensure a constant supply of fresh water.

Mites: These tiny parasites can be introduced through substrate or food. Regular cleaning and proper husbandry are essential.

Mold: Can develop in overly humid enclosures. Ensure proper ventilation.

Falls: Avoid allowing the tarantula to climb too high in the enclosure, as falls can be fatal, especially during or immediately after a molt.

Conclusion:

The Phormictopus auratus is a rewarding species to keep for experienced tarantula enthusiasts. Their vibrant colors and interesting behaviors make them a captivating addition to any collection. By understanding their specific care requirements and providing a safe and comfortable environment, you can ensure the well-being of your shimmering Caribbean Bronze for years to come. Remember to always research thoroughly and observe your tarantula closely to understand its individual needs. Happy tarantula keeping!
