Cyriocosmus perezmilesi - Bolivian dwarf beauty tarantula



Cyriocosmus perezmilesi: The Bolivian Dwarf Beauty -
The Heart-butt tarantula

Introducing the Cyriocosmus perezmilesi, commonly known as the Bolivian Dwarf Beauty. This tiny tarantula, native to Bolivia, is a delightful addition to any collection, known for its striking appearance and manageable size. Despite its small stature, the Bolivian Dwarf Beauty captivates with its vibrant coloration and distinctive patterns.

Care Details:

  • Temperature: Ideal range for most tarantulas is 75 to 85°F (24 to 29°C). Tarantulas in warmer environments eat more, grow faster, and molt quicker. This care flexibility makes tarantulas easy to maintain.
  • Humidity: 60-70%. Water dishes are not necessary, but if used, they pose no harm. I personally do not use them.
  • Housing:
    • Terrestrial species: A 1 oz to 4 oz deli container with needle-made ventilation. Free containers available at checkout. For larger tarantulas, an enclosure 2 to 3 times their size, with some flexibility. I will include a free deli container or small enclosure for babies, but you must specify during checkout that you would like one, or it will not be included with the order, so you MUST ask.


I personally give them a variety of crickets and cockroaches, including Dubia, Red-runner, Lobster, and Madagascar hissing roaches. For the baby tarantulas, baby crickets and baby roaches are ideal. If you have access to only one type of prey, that is also perfectly fine.

If you cannot find a small enough cricket or cockroach, just crush its head and leave it in the enclosure; your tarantula should handle the rest. Remember to remove any uneaten food to prevent any mold growth. And for an occasional treat, a pinky or hopper mouse adds a nice variety to their diet. Make sure to not overfeed rodents and feeder lizards to your tarantulas, these should be done every once in a while as a treat. Too much calcium is not good for the tarantula as it can cause constipation and the tarantula might have a hard time pooping.

Safety Disclaimer:

Experiencing a tarantula bite is an extremely rare occurrence, and it's important to note that there have been no recorded fatalities due to a tarantula bite. The venom potency varies across species, with Old World tarantulas generally having stronger venom than their New World counterparts. Within the Old World category, the Poecilotheria genus is known for having particularly potent venom.

It's crucial to approach tarantulas with respect and understanding. If you happen to get bitten, which is unlikely, the key is to stay calm. In most cases, the discomfort is superficial and subsides within a few minutes to a few hours. However, bites from species with more potent venom may result in symptoms lasting up to a week. Remember, larger tarantulas tend to have more venom than smaller ones.

Please be aware that I cannot assume responsibility for bites. Tarantula handling should be done at your own risk. In my 11 years of experience with these creatures, I have only been bitten once, by a species with highly potent venom. While the experience was painful, the symptoms had completely disappeared after a week.

Handle tarantulas responsibly, and always prioritize your safety and the well-being of the tarantula.
