Poecilotheria regalis (Indian Ornamental Tarantula)

Poecilotheria regalis (Indian Ornamental Tarantula)

Poecilotheria regalis, commonly known as the Indian Ornamental Tarantula, is a large, highly patterned arboreal species known for its clean black and white contrast and fast, alert behavior. As a spiderling, it begins with a detailed, banded pattern across the abdomen and carapace (head), which becomes more defined with each molt. By adulthood, it develops a sharp, structured pattern with bold black and white contrast across the body, including a strong central abdominal marking and distinct banding along the legs. Subtle blue to purple tones can be seen in the legs under certain lighting, while bright yellow and white markings underneath the legs become visible during movement.

This is a true arboreal species that lives in vertical retreats and is most active at night, typically remaining hidden during the day and emerging after dark. It relies on speed and retreat behavior rather than webbing, and when given proper structure, it will consistently use its retreat and remain predictable within the enclosure.

Why Hobbyists Keep Poecilotheria regalis

• High-contrast patterning: Clean black and white adult pattern with a bold central abdominal marking and bright yellow banding underneath the legs
• Temperament: Fast and reactive, but typically retreat-focused when provided with proper space and structure
• Webbing behavior: Minimal webbing behavior, relying on vertical retreats rather than building visible web structures
• Adult size and behavior: Reaches a maximum leg span of around 6.5 to 7 inches, with a long-legged arboreal build and active nighttime behavior
• Feeding response and activity level: Strong feeding response with a fast, and vigorous hunting style,  often more active during evening hours

Care Overview

• Enclosure: Provide a tall arboreal setup with about 2× the leg span as floor space and at least 3× the leg span as height, including vertical cork bark or hollow structures for retreat
• Temperature: Maintain between 65–75°F with stable conditions
• Humidity: Maintain moderate humidity with good airflow, keeping conditions slightly moist but never stagnant
• Diet: Feed crickets, roaches, or similar prey sized appropriately to the carapace (head); this species typically feeds readily and can take larger prey than many other arboreals
• Temperament: Fast and alert, more likely to retreat quickly than display defensive behavior

Additional Notes or Considerations

This species spends most of its time in a vertical retreat during the day, often pressed flat against cork bark in a stretched posture that helps it blend into tree surfaces. Its patterning breaks up its outline, making it difficult to spot when at rest, especially against bark.

At night, it becomes significantly more active, emerging to hunt and move throughout the enclosure. This day-to-night shift is important to understand, as it may appear inactive during the day but is actually highly active after dark.

Strong ventilation is important for this species. Like most arboreal tarantulas, it benefits from consistent airflow and should not be kept in overly damp or stagnant conditions.

Providing a proper vertical retreat is critical. Without a cork bark tube or similar structure, this species may feel exposed and behave unpredictably. When given structure, it becomes far more consistent and manageable.

Pro tip: for higher visibility during the day take a cork bark that is cut flat so it stands up on its own, cut it in half longways and put it in the corner - this creates a "tree hollow" that is partailly glass or acrylic so if you just want to take a peak during the day you can.

The underside leg banding seen in this species is a defining trait of the genus and can be used to distinguish between different Poecilotheria species.
