"Bryantae" Locale: Bold Jumping Spider (Phidippus audax)

Stage: i4 (4th Instar) | Origin: Captive Bred

The Bryantae Advantage

  • Striking Monochrome Patterning: Phidippus audax Bryantae are renowned for their crisp, high-contrast black-and-white markings — bold abdominal spots and vivid banding that remain striking throughout their entire life, not just in adulthood.
  • Electric Green Chelicerae: One of the most eye-catching features of P. audax — their iridescent, metallic green mouthparts shimmer brilliantly under light, making them one of the most visually arresting jumping spiders available in the UK hobby.
  • Compact & Charismatic: Smaller and more compact than Phidippus regius, the Bryantae locale is no less bold. These spiders are intensely curious, highly interactive, and known for their fearless, head-on engagement with their keepers.
  • A True Collector’s Spider: The Bryantae locale of P. audax is a sought-after variant within the hobby, prized for its consistent patterning and personality. An excellent addition for both beginners and experienced keepers alike.

Specifics for i4 Slings

  • Size: Currently approx. 4–6mm (roughly the size of a garden pea).
  • Current Diet: Hunting Drosophila hydei (Large Fruit Flies) with high accuracy.
  • Appearance: At the i4 stage, their signature black-and-white patterning is already visible and well-defined. Their chelicerae will develop their full metallic green iridescence as they mature through successive moults.
  • Sexing: Sold as unsexed. Gender-specific traits will become clearer as they mature.

The Growth Journey: Transitioning Feeders

Our i4 Bryantae slings are established on fruit flies, but as they grow into confident juveniles, their appetite will graduate.

  • Future Diet: We recommend transitioning to Green Bottle flies at the i6 or i7 stage. These provide excellent enrichment and the ideal nutritional profile for a growing P. audax.
  • Expert Guide: For a full breakdown on moving your spider to larger prey, read our feeding and transition blog post here.

Important Shipping Update

We dispatch all live spiders exclusively via Royal Mail Special Delivery (Guaranteed by 1pm). The welfare of our spiders is our absolute priority:

  • Reliability: Special Delivery bypasses the standard post, minimising time in the mail system.
  • Priority Handling: Your spider won’t be left sitting in a delivery office during a backlog.
  • Reduced Stress: A faster journey means your spider arrives healthy, hydrated, and ready for their new home.

Please Note: To avoid your spider being held in a sorting office over the weekend, we only post orders from Monday to Thursday.

📷 About Our Photos: Variation & Potential

Please Note: The images provided include photos of our actual i4 spiderlings currently in stock. Because these are unsexed juveniles, they have not yet fully developed their adult colouration. Phidippus audax Bryantae become increasingly striking with each moult — their chelicerae deepening in iridescence and their patterning sharpening as they grow. Every spider is a unique individual!

Note on Sexing: This spider is sold as unsexed. If you have a preference for a male or female, please message us — we’ll always do our best to find your perfect match.
