Cilantica devamatha - Psychedelic Earth Tiger - Sling

Cilantica devamatha, commonly known as the Psychedelic Earth Tiger or Indian Rainbow Tarantula, is a stunning Old World fossorial species native to India. Known for its metallic iridescence and deep burrowing behavior, this species has long been a favorite among experienced keepers who appreciate its vibrant coloration and intricate webbing tendencies.

This species has undergone taxonomic revisions, and some hobbyists may still refer to it by previous names or common names. Historically, it was grouped with other Haploclastus species before being formally described as Haploclastus devamatha. It is also known by various common names, including Indian Violet Earth Tiger, Indian Blue Tarantula, LSD Earth Tiger and Devamatha Earth Tiger. Understanding these name changes is important for identifying this species in the hobby and distinguishing it from similar-looking Indian fossorial tarantulas.

Like other members of the Haploclastus genus, H. devamatha is a fast, defensive species with potent venom, making it unsuitable for beginners. However, for experienced keepers looking for a vibrant, fossorial species with incredible webbing behavior, this tarantula is a rewarding addition to any collection.
