Natural History

In the wild, Cyriocosmus perezmilesi inhabits tropical environments where it constructs small burrows beneath leaf litter, roots, and forest debris. These silk-lined retreats provide protection from predators and help maintain stable humidity.

The Bolivian Dwarf Tarantula spends much of its time inside these hidden retreats, emerging primarily at night to hunt small insects and other prey moving across the forest floor.

Warm temperatures and moderate humidity similar to its natural environment should be maintained in captivity to support healthy growth.

Temperament

Cyriocosmus perezmilesi is typically quick and alert, though it rarely shows aggressive behavior. When disturbed, the spider generally retreats into its burrow or webbed hide.

Like other New World tarantulas, the Bolivian Dwarf Tarantula possesses urticating hairs which it may kick if threatened.

Because of its small size and active nature, this species is best appreciated as an observation tarantula.

Enclosure Setup

Due to its small size, the Bolivian Dwarf Tarantula can be housed in a compact enclosure with a naturalistic setup.

Recommended enclosure features include:

• several inches of substrate for burrowing

• cork bark or small hides

• moderate humidity

• good ventilation

• a shallow water dish

This species will often construct silk tunnels and burrow systems throughout the enclosure.

Feeding

Like most tarantulas, Cyriocosmus perezmilesi feeds primarily on small 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 Bolivian Dwarf Tarantula often displays a surprisingly strong feeding response for its small size.

Molting and Growth

Tarantulas grow through molting, shedding their old exoskeleton as they increase in size.

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

As Cyriocosmus perezmilesi matures, its coloration and distinctive abdominal markings often become more pronounced.
