Chilobrachys dyscolus – Vietnam Blue Tarantula

Species Overview

Chilobrachys dyscolus -Vietnam Blue Tarantula, is a striking Old World tarantula species prized in the hobby for its deep metallic blue legs, dark body, and robust build. Native to Vietnam and nearby regions of Southeast Asia, this terrestrial and fossorial spider inhabits warm, humid forested areas where it constructs extensive burrows in the soil.

Temperament and Behaviour

This species is known for its defensive temperament, strong threat posture, and rapid movements, making it more suitable for experienced tarantula keepers. As a fossorial tarantula, it spends much of its time underground, creating intricate tunnel systems and heavily webbed retreats. In captivity, a deep substrate layer, secure hides, and stable humidity are essential for its well‑being and to encourage natural burrowing behavior.

Size, Coloration, and Feeding

The Vietnam Blue Tarantula is a medium to large species, with adults displaying vivid blue coloration on the legs that intensifies after each molt. It is a fast‑growing tarantula with a strong feeding response, typically preying on common feeder insects such as crickets, roaches, and other appropriately sized invertebrates. Due to its potent venom, speed, and defensive nature, it is generally considered a display tarantula rather than a species suitable for handling.

Care Requirements in Captivity

Responsible care of Chilobrachys dyscolus focuses on providing a secure, escape‑proof enclosure, deep substrate for burrowing, appropriate temperature and humidity, and minimal disturbance. Enthusiasts value this tarantula for its unique blue coloration, impressive webbing behaviour, and fascinating burrowing lifestyle, making it a standout species in any Old World tarantula collection.
