Regal Jumping Spider
Phidippus regius
Salticidae (Jumping Spiders), Order Araneae. Characterized by excellent vision and hydraulic jumping ability.
Physical Description
A robust, fuzzy jumping spider with a square-shaped cephalothorax and an ovoid abdomen. Known for significant sexual dimorphism; this specimen is a female, appearing stocky with dense setae (hairs) and iridescent chelicerae (mouthparts).
Size Estimate
Estimated body length 15-22mm. This specimen appears to be an adult female, which are among the largest jumping spiders in North America.
Coloration & Markings
Females range from gray to bright orange; this individual exhibits a white/gray phase. Features iconic iridescent chelicerae, often pink, violet, or green. The abdomen typically has a central triangular spot and two smaller spots.
Web Type
Does not build a hunting web. Instead, it constructs a silken 'pup-tent' or retreat for sleeping, molting, and laying eggs. It uses a silken dragline as a safety tether when jumping.
Eye Arrangement
Four pairs of eyes. The Anterior Median Eyes (AME) are massive and forward-facing, providing high-resolution telescopic vision. The remaining eyes provide a 360-degree field of view.
Leg Characteristics
Thick, hairy legs adapted for jumping. The front pair is slightly longer and used for grasping prey and communication. They lack the long spines typical of orb-weavers.
Venom & Safety Information
Venom Information
Hemipteran-specific venom intended for small insects. It is not considered toxic to humans or domestic pets like dogs and cats.
Medical Significance
Harmless to humans. A bite is extremely rare and usually occurs only if the spider is squeezed. Symptoms are comparable to a mild bee sting (local redness and swelling). No specific treatment required.
Safety Recommendations
No safety concerns. If found indoors, they can be easily captured with a cup and paper and relocated to a tree or porch.
Habitat & Behavior
Habitat & Range
Primarily the Southeastern United States (Florida, Georgia, South Carolina) and the Greater Antilles. Common in open woodlands, field edges, and frequently found on man-made structures.
Behavior & Temperament
Curious and intelligent diurnal active hunter. They track prey visually like a cat and jump many times their body length. Generally very docile and popular in the exotic pet trade.
Diet & Prey
Generalist predator feeding on insects such as flies, crickets, and moths, and occasionally other spiders. They pounce and deliver a quick paralyzing bite.
Seasonal Activity
Active year-round in warmer climates like Florida; peak activity and mating occur in spring and summer.
Description
The Regal Jumping Spider is a charismatic micro-predator. With its large, soulful eyes and fuzzy appearance, it is often cited as a 'gateway spider' that helps people overcome arachnophobia.
Key Features
Large size, iridescent chelicerae, and the specific four-spot pattern on the abdomen are diagnostic of the Phidippus genus.
Similar Species
Phidippus audax (Bold Jumper), which is usually black with a white/metallic green spot and prefers slightly different habitats.
Life Cycle
Females lay silk-covered egg sacs containing 50-200 eggs. Spiderlings disperse via 'ballooning'. They live approximately 1 to 2 years, molting several times before reaching maturity.
Ecological Importance
Critical for natural pest control, keeping populations of flies and agricultural pests in check within its territory.
Conservation Status
Not evaluated by IUCN, but currently considered stable. They are widespread throughout their native range.
Interesting Facts
They have one of the most sophisticated visual systems of any invertebrate, capable of perceiving color and depth. They are known to 'watch' humans and follow moving objects with their heads.
Photography Tips
Focus sharply on the large central eyes. Use a macro lens and a diffused flash to reveal the iridescence of the chelicerae without creating harsh highlights on the hairs.
