Bold Jumping Spider, Daring Jumping Spider, Orchard Spider
Phidippus audax
Family Salticidae (Jumping Spiders), Order Araneae
Physical Description
A robust, hairy spider with a relatively flat cephalothorax and an ovoid abdomen. Known for its stocky build and large, forward-facing eyes, giving it a 'chubby' or 'cute' appearance compared to other arachnids.
Size Estimate
Body length 8–20 mm; leg span 20–35 mm. Based on the photo, this appears to be a mature adult specimen.
Coloration & Markings
Primarily black with white or orange-colored spots on the abdomen. A distinctive large central spot is flanked by two smaller spots. The chelicerae (mouthparts) are often brilliant iridescent green or blue.
Web Type
Does not build a traditional capture web. Instead, it constructs small silken 'pup-tents' or retreats in crevices for molting, sleeping, and egg-laying.
Eye Arrangement
Four pairs of eyes. The Anterior Median Eyes (AME) are extremely large and forward-facing, providing excellent binocular vision and depth perception, characteristic of the Salticidae family.
Leg Characteristics
Relatively short, thick, and powerful legs covered in fine hairs. The front pair is slightly longer and heavier for grasping prey. They possess specialized claw tufts (scopulae) for climbing smooth surfaces.
Venom & Safety Information
Venom Information
Possesses venom used to immobilize prey. It is not considered toxic to humans; the chemical composition is designed for invertebrate physiology.
Medical Significance
Harmless to humans. Bites are extremely rare and usually only occur if the spider is roughly handled. Symptoms are typically less severe than a bee sting (mild localized pain or redness).
Safety Recommendations
No special safety measures required. If found indoors, they can be easily moved outside using a cup and card. Relocation is preferred over extermination as they are beneficial predators.
Habitat & Behavior
Habitat & Range
Common throughout North America (Canada, USA, Mexico). Found in open habitats including grasslands, field edges, gardens, and frequently on the exterior walls of buildings.
Behavior & Temperament
Active diurnal hunters with high intelligence and inquisitiveness. They use their vision to track prey and pounce from a distance like a cat. Generally very shy of humans and not aggressive.
Diet & Prey
Generalist predators feeding on various insects such as flies, moths, and crickets, as well as other spiders. They use a 'dragline' of silk as a safety tether before leaping at prey.
Seasonal Activity
Most visible in late spring through early autumn. In colder regions, they may overwinter as sub-adults in silken sacs hidden under bark or in building eaves.
Description
The Bold Jumping Spider is one of the most charismatic arachnids in North America. Its large, soulful eyes and curious behavior make it a favorite for nature enthusiasts. It functions as a miniature lion in the garden, stalking pests with military precision.
Key Features
Large central abdominal spot; iridescent green chelicerae; two massive forward-facing eyes; hairy black body.
Similar Species
Phidippus regius (Regal Jumping Spider) which is larger and found in the SE USA; Paraphidippus aurantius which has different abdominal patterns.
Life Cycle
Females lay egg sacs in silken retreats during summer. Spiderlings emerge and often disperse via 'ballooning' on silk threads. They can live up to two years in some climates.
Ecological Importance
Critical for natural pest control in gardens and agriculture, preying on pests like boll weevils and harmful flies.
Conservation Status
Not evaluated by IUCN; however, they are widely distributed and considered common with stable populations.
Interesting Facts
They have better vision than many vertebrates and can see in color. They are also known to participate in complex courtship dances involving rhythmic leg waving and vibrations.
Photography Tips
Focus sharply on the front eyes. Since they are curious, they will often look directly at the lens. Use a macro lens or high magnification with good natural light to capture the iridescent mouthparts.
