Bold Jumper, Bold Jumping Spider, Daring Jumping Spider, Orchard Jumper
Phidippus audax (probable)
Salticidae (Jumping Spiders), Order Araneae. Characterized by excellent vision and active hunting.
Physical Description
Compact, robust body with a somewhat flattened cephalothorax and an oval abdomen. They are covered in dense setae (hairs) giving them a fuzzy appearance. They have exceptionally large anterior median eyes.
Size Estimate
Body length 8-15mm; total leg span varies. This specimen appears to be a sub-adult or adult based on robust proportions.
Coloration & Markings
Primarily black or dark brown with a distinct white, orange, or yellow spot in the center of the abdomen, accompanied by smaller spots or chevrons toward the rear. Chelicerae (mouthparts) often show iridescent green or blue.
Web Type
They do not build hunting webs. They create small silk 'pup tents' or retreats for molting, sleeping, and protecting egg sacs, typically in crevices or under bark.
Eye Arrangement
Four pairs of eyes: two extremely large Anterior Median Eyes (AME) for detail, flanked by smaller Anterior Lateral Eyes, with four smaller eyes on the top of the cephalothorax providing a 360-degree view.
Leg Characteristics
Thick, powerful legs, particularly the first pair which are often used for grasping prey and during mating displays. Legs are hairy and ends have specialized pads (scopulae) for climbing smooth surfaces.
Venom & Safety Information
Venom Information
Weakly cytotoxic and neurotoxic to insects. For humans, it is very mild and not considered medically significant; potency is comparable to a bee sting.
Medical Significance
Harmless. Bites are rare and usually occur only if the spider is pinched or handled roughly. Symptoms include localized redness, slight swelling, and itching.
Safety Recommendations
No action is typically needed. If found indoors, they can be easily moved outside using the 'cup and paper' method. They are beneficial to have around and pose no threat to pets or humans.
Habitat & Behavior
Habitat & Range
Common across North America (USA, Canada, Mexico). Found in fields, backyards, gardens, and frequently inside homes on windowsills or walls.
Behavior & Temperament
Diurnal, active hunters that track prey visually before pouncing. Curiously bold and often track human movement with their eyes; generally non-aggressive and will jump away if threatened.
Diet & Prey
Generalist predators feeding on various insects, including flies, moths, beetles, and occasionally other spiders. They use their hydraulic leg pressure to leap up to 50 times their body length.
Seasonal Activity
Most visible in late spring through autumn. They may overwinter as sub-adults in silk retreats tucked into sheltered locations.
Description
Bold Jumping Spiders are the 'charismatic megafauna' of the spider world. With their large, expressive eyes and fuzzy bodies, they are often used to help people overcome arachnophobia. They are intelligent, visual hunters that act more like tiny cats than typical spiders.
Key Features
Single large spot on back of abdomen, iridescent green chelicerae, and the characteristic jumping spider 'face' with two massive front eyes.
Similar Species
Phidippus regius (Regal Jumper) found in SE USA, and Platycryptus undatus (Tan Jumper) which is flatter and lacks the central spot.
Life Cycle
Males perform elaborate dancing displays to attract females. Females lay eggs in silk-lined retreats. Spiderlings disperse via 'ballooning' (floating on silk threads in the wind).
Ecological Importance
Critical for natural pest control in gardens and agriculture, consuming significant numbers of crop-damaging insects and flies.
Conservation Status
Not evaluated by IUCN, but currently widespread and abundant with no known major threats.
Interesting Facts
They are capable of complex navigation and can plan routes to prey that involve losing sight of the victim temporarily. They also have a 'safety line' of silk they attach before jumping.
Photography Tips
Get on their level for a 'eye-contact' shot. Use a fast shutter speed to catch them before they jump. Macro lenses are ideal to capture the iridescent mouthparts.
