Bold Jumping Spider, Daring Jumping Spider, Orchard Spider
Phidippus audax
Salticidae (Jumping Spiders), Order Araneae. Characterized by excellent vision and hydraulic jumping ability.
Physical Description
Compact, robust body with a somewhat flat cephalothorax and an oval-shaped abdomen. The body is covered in dense hairs, giving it a fuzzy appearance. They have large, powerful chelicerae (mouthparts) that are often iridescent.
Size Estimate
6mm to 15mm for adults. Since this specimen was described as very tiny, it is likely a juvenile or a smaller male. Leg span is typically 1.5 to 2 times the body length.
Coloration & Markings
Predominantly black or deep brown with a distinctive white, orange, or yellow triangular spot in the center of the abdomen, flanked by two smaller spots. Juveniles often have orange markings that turn white as they mature. The chelicerae are famously iridescent green or blue.
Web Type
The Bold Jumper does not build a traditional capture web. Instead, it spins small silken retreats or 'pup tents' for molting, sleeping, and egg-laying. It is an active hunting spider.
Eye Arrangement
Eight eyes in three rows. Two massive Anterior Median Eyes (AME) provide high-resolution binocular vision, flanked by two smaller lateral eyes. Four smaller eyes are located on the top and sides of the head for motion sensing.
Leg Characteristics
Strong and thick legs adapted for jumping. The front pair is the robust and often held in a raised position. They are covered in sensory hairs and lack the long spines found on many web-building spiders.
Venom & Safety Information
Venom Information
Contains proteins designed to immobilize small insects. It is not considered dangerous to humans. Potency is very low for mammals.
Medical Significance
Harmless. Bites are rare and usually only occur if the spider is pinched or crushed. Symptoms are similar to a bee sting (minor swelling and redness). No special treatment is usually required.
Safety Recommendations
No action is needed. If found in a car or home, they can be easily relocated by placing a cup over them and sliding a piece of paper underneath to carry them outside.
Habitat & Behavior
Habitat & Range
Common throughout North America, including West Virginia. Habitats range from grasslands and prairies to agricultural fields and urban environments like gardens, houses, and cars.
Behavior & Temperament
Highly intelligent and curious active hunters. They use their exceptional vision to track prey and jump many times their body length. They are generally non-aggressive toward humans and will usually move away when approached.
Diet & Prey
Generalist predators consuming a variety of insects like flies, moths, and beetles. They use a 'stalk and pounce' method, often tethering themselves with a silk safety line before jumping.
Seasonal Activity
Most active from late spring through autumn. Large adults are frequently seen in late summer during mating season.
Description
The Bold Jumping Spider is one of the most charismatic arachnids in North America. With its fuzzy body and large, curious eyes, it often behaves more like a mammal than a typical spider, tracking viewers with its head. Its jumping prowess is unmatched, powered by sudden changes in internal fluid pressure.
Key Features
Large iridescent green/blue chelicerae; central triangular spot on the dorsal abdomen; large front-facing eyes; hairy, 'stocky' appearance.
Similar Species
Phidippus regius (Regal Jumper) found further south; Phidippus princeps (shorter, less distinct markings).
Life Cycle
Females lay eggs in silk sacs within their retreats. Spiderlings emerge and often disperse via 'ballooning.' They undergo several molts before reaching adulthood, with a typical lifespan of about one year in the wild.
Ecological Importance
Significant biological control agents in gardens and farms, keeping populations of agricultural pests like boll weevils and flies in check.
Conservation Status
Not evaluated by IUCN, but considered common and stable throughout its range.
Interesting Facts
They have 360-degree vision and can see a wide range of colors, including UV. They are known to engage in complex mating dances involving rhythmic leg waving.
Photography Tips
Focus strictly on the front of the spider to capture the large eyes and iridescent chelicerae. Use a high shutter speed to account for their sudden, jerky movements.
User Notes
I found him on the car when we were parked in a parking lot of a restaurant. He is very tiny, and he is in Chester, West Virginia, USA. What kind of jumping spider is he?
