The Unassuming Charm of the Regal Jumping Spider

Physical Characteristics

The regal jumping spider (Phidippus regius) is a small but striking arachnid that’s easily recognizable due to its incredible jumping ability and vibrant colors. Adult males are about 0.47 inches (12 mm) long on average, while adult females are slightly larger at around 0.59 inches (15 mm) long.

These spiders have distinct color patterns, with adult males typically featuring black bodies and iridescent green-blue-violet chelicerae (mouthparts). They also often display alternating black and white markings along their abdomens. Female regal jumping spiders are more variable in terms of coloration, with pale brown, reddish-brown markings or even orange-white markings.

Are Regal Jumping Spiders Harmless?

Regal jumping spiders are not a threat to human health. They rarely bite, and even when they do, their venom is harmless. The bite may cause mild irritation, but it’s nothing to be concerned about. These spiders are more interested in small-winged insects than people, and they’re actually beneficial to have around as natural pest controllers.

Habitat and Distribution

Regal jumping spiders thrive in a variety of habitats across eastern North America. They’re commonly found in light woodland areas, gardens, and fields. You might spot them hiding among palm fronds or exploring wooden structures like fences and sheds. These spiders create silken nests in hidden crevices, under bark, or within leaves.

What Attracts and Deters Regal Jumping Spiders?

Regal jumping spiders are attracted to areas with abundant hunting grounds, such as gardens and fields full of small-winged insects. Wooden structures like fences and porches can also serve as prime real estate for their silken nests. To deter these spiders, reduce clutter and seal cracks in your home where they might build nests. However, keep in mind that these spiders are natural pest controllers and pose no harm. They’re more likely to help you out by keeping insect populations in check.
