Phiddipus Bidensis - Jumping Spider

Bidensis Jumping Spider (Phidippus bidentatus)

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

The Bidentatus Advantage

• Intricate Patterns: Unlike the solid colour phases of the regius, bidentatus females often display beautiful "chain" or "skull" patterns on their abdomens in shades of tan, cream, and gold.
• High-Contrast Males: Adult males are stunningly jet-black with crisp, snowy-white bands, making them one of the most striking "tuxedo" spiders in the genus.
• Active & Inquisitive: This species is known for being slightly faster and more "springy" than Regals. They are relentless explorers and rarely stay in one spot for long.
• Compact Powerhouse: While they don't reach the "giant" size of an Everglades Regal, they are robust and stocky, making them very capable hunters from a young age.

Specifics for i4 Slings

• Size: Currently approx. 5mm (roughly the size of a small pea).
• Current Diet: Hunting Drosophila hydei (Large Fruit Flies) with extreme precision.
• Appearance: At i4, they are mostly dark with distinct white abdominal spots. Their intricate "chain" patterns will begin to develop and lighten over the next few molts.
• Sexing: Sold as unsexed. True to the species, males and females start to look distinct around i6–i7.

UK Care Requirements

• Humidity: 60% – 70%. They prefer it slightly "drier" than the Everglades locale. A light misting every 2 days is usually sufficient—ensure the enclosure dries out between mistings.
• Temperature: They love the heat. Aim for 25°C – 29°C. A thermostat-controlled heat mat is highly recommended for UK keepers to keep this Central American species at its most active. Read our blog post here
• Lighting: Strong, bright light is essential. P. bidentatus are sun-lovers and will spend most of their time basking in the brightest spot of the enclosure.

The Growth Journey: Transitioning Feeders

Our i4 bidentatus slings are established on fruit flies, but they are ambitious hunters who love a challenge as they grow.

• Future Diet: We recommend transitioning to Green Bottle flies at the i6 or i7 stage. Their high energy levels make them excellent "aerial" hunters, often catching flies mid-air.
• Expert Guide: For a full breakdown on how to move your spider from fruit flies to larger prey, read our feeding and transition blog post here.

Important Shipping Update

​We have made the decision to dispatch all live spiders exclusively via Royal Mail Special Delivery (Guaranteed by 1pm).

​The welfare of our spiders is our absolute priority, and we have implemented this policy for the following reasons:

• ​Reliability: Unfortunately, services such as Tracked 24 have recently seen an increase in delayed or lost parcels. When it comes to a living creature, we simply cannot take that risk.
• ​Priority Handling: Special Delivery is a premium service that bypasses the standard post. This means your spider spends as little time as possible in the mail system and isn't left sitting in a delivery office during a backlog.
• ​Reduced Stress: A faster journey means less stress for the spider, ensuring they arrive healthy, hydrated, and ready for their new home.

​Please Note: To avoid any risk of 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.

However, because these are unsexed juveniles, they have not yet developed their adult colours. Like all Phidippus regius, they undergo a spectacular transformation as they grow. While the Apalachicola lineage is renowned for its "White Phase" potential, every spider is a unique individual. The final adult colouration—whether it be snow-white, silver, or light grey—is a result of genetic diversity, making the journey of watching your sling grow an exciting "unboxing" of its true traits!

Note on Sexing:

This spider is sold as unsexed. If you have a preference for a male or female, please message us! We can’t guarantee it, but we’ll always do our best to find your perfect match.
