Natural History

In the wild, Dolichothele diamantinensis inhabits dry scrublands and forest edges in parts of Brazil. These tarantulas construct silk-lined retreats beneath rocks, roots, and soil debris where they remain hidden during the day.

The Brazilian Blue Dwarf Beauty Tarantula relies heavily on webbing to create shelter and detect vibrations from nearby prey. At night, it emerges from its retreat to hunt small insects moving across the ground.

This species thrives in warm environments with moderate humidity and good airflow.

Enclosure Setup

Due to its smaller size, the Brazilian Blue Dwarf Beauty Tarantula can be housed in a relatively compact enclosure, though it still benefits from a naturalistic setup.

Recommended enclosure features include:

• several inches of substrate

• cork bark or small hides for retreats

• moderate humidity

• good ventilation

• a shallow water dish

This species will often construct silk retreats beneath its hide or throughout the enclosure.

Feeding

Like most tarantulas, Dolichothele diamantinensis feeds primarily on insects such as:

• small crickets

• roach nymphs

• other appropriately sized feeder insects

Juveniles may be fed once or twice per week, while adult specimens typically feed every 7–10 days depending on size.

The Brazilian Blue Dwarf Beauty Tarantula often displays an enthusiastic feeding response.

Molting and Growth

Tarantulas grow through a process known as molting, where they shed their exoskeleton and emerge slightly larger.

Before molting, the spider may refuse food and remain hidden in its retreat. After molting, it should be left undisturbed while its new exoskeleton and fangs harden.

Following molts, the metallic blue coloration of Dolichothele diamantinensis often becomes more vivid.
