Bold Jumping Spider, Daring Jumping Spider
Phidippus audax
Salticidae (Jumping Spiders), Order Araneae
Physical Description
A robust, hairy jumping spider with a square-shaped cephalothorax and an ovoid abdomen. Known for its powerful build and enlarged front legs. They are covered in dense setae (hairs).
Size Estimate
Body length typically ranges from 13-20mm for females and 6-15mm for males. This specimen appears to be an adult female based on its substantial abdominal volume.
Coloration & Markings
Predominantly black with a distinct large white, orange, or yellow triangular spot in the center of the abdomen, accompanied by two smaller spots toward the rear. The chelicerae (mouthparts) are often a shimmering iridescent metallic green or blue.
Web Type
Non-web builder for hunting. They use silk only to create 'pup tents' or silken retreats for molting, sleeping, and protecting egg sacs.
Eye Arrangement
Four pairs of eyes with two very large, forward-facing Anterior Median Eyes (AME) that provide high-resolution binocular vision, specialized for tracking prey.
Leg Characteristics
Short, thick, and powerful legs. The first pair is noticeably heavier and more fringed with hair, used for grasping prey and during courtship displays.
Venom & Safety Information
Venom Information
Contains necrotizing factors but is not considered medically significant to humans. Potent against insect prey but typically results in only localized pain for people.
Medical Significance
Harmless to humans. Bites are rare and usually comparable to a bee sting, resulting in minor redness and swelling. No special medical treatment is typically required.
Safety Recommendations
No action is necessary. They are beneficial neighbors. If relocation is desired, they can be easily moved with a cup and a piece of paper.
Habitat & Behavior
Habitat & Range
Native to North America. Found in gardens, grasslands, open woodlands, and frequently on the exterior of homes, fences, and mailboxes seeking sunlight.
Behavior & Temperament
Diurnal active hunter. They are famously curious and intelligent-acting spiders that track movement with their heads. Generally docile and reluctant to bite unless squeezed.
Diet & Prey
Feeds on a wide variety of insects including flies, moths, beetles, and even other spiders. They hunt by stalking and then pouncing with a tethered silk safety line.
Seasonal Activity
Peak activity is from late spring through fall. They are often seen sunning themselves on vertical surfaces during warm afternoons.
Description
The Bold Jumping Spider is one of the most charismatic arachnids in North America. With its fuzzy appearance and large, curious eyes, it is often called the 'gateway spider' for arachnophobes.
Key Features
Large central white abdominal spot, iridescent green chelicerae, and the ability to track movement by turning its cephalothorax.
Similar Species
Phidippus regius (Regal Jumping Spider) which is found in the SE US and has more varied female coloration, and Paraphidippus aurantius.
Life Cycle
Females lay several egg sacs in summer within silken retreats. Spiderlings emerge and often 'balloon' to new locations. Can live up to 1-2 years in the wild.
Ecological Importance
Crucial for natural pest control in gardens and agricultural fields, consuming significant quantities of plant-damaging insects.
Conservation Status
Not evaluated (Stable). They are widespread and highly adaptable to human-dominated landscapes.
Interesting Facts
They have vision comparable to that of a cat in terms of complexity and can jump up to 50 times their body length to catch prey.
Photography Tips
Since they track movement, move slowly. If you wiggle a finger near the lens, the spider will often look directly at the camera for a 'portrait' shot.
