Phidippus Pius - Juvenile

Pius are one of the smaller Phidippus species and are slow growers, so don’t expect them to size up quickly. What they lack in size, they make up for with personality, curiosity, and adorable faces. Even as adults, they stay much smaller than Regius, making them a great option for anyone who appreciates the little things. 

Each of our jumping spiders is captive bred and lovingly raised until they’re ready for their forever homes. We encourage all adopters to research proper care to ensure their new companion thrives. Check out our [Care Guide] for helpful tips!

Tiny Spider Alert! These little ones are still very small and growing at their own pace. Pius are naturally slow growers, so expect them to stay tiny longer than species like Regius. They may still require fruit flies (D. melanogaster) or other small feeders for a while. Keeping them in appropriately sized homes makes feeding, maintenance, and monitoring much easier, which is why every Pius order includes a decorated temporary 2.5 oz cup. This cozy little home is suitable for several molts before an upgrade is needed.

Captive-Bred Jumping Spider for Adoption

• Species: Phidippus Pius

• Sex: Unsexed

• Mom: Ivory [See Photos]

• Origin: Captive bred

• Instar: i6/i7

• Phase/Variation: NA

• Diet: D. Melanogastar & D. hydei Fruit Flies/Micro Mealworms

  • Typical feeder progression:

    • D. melanogaster → smallest fruit flies

    • D. hydei → larger fruit flies

    • Micro/Mini mealworms

    • Small mealworms

    • Larger prey as the spider grows

    For Pius, especially early juvenile stages, melanogaster are often the preferred feeder because Pius grow slowly and stay tiny longer than species like Regius. Many Pius will spend quite a while on melanos before moving up to hydei or very tiny mealworms.
