- Are black overall, with three white spots on their dorsal abdomens and a narrow white band around the front of their abdomens which taper down their sides.
- May have a thin white stripe on their cephalothoraxes that extend from their posterior lateral eyes to the back of their carapaces.
- Have iridescent green chelicerae.
- Male Bold Jumping Spiders:
- Grow up to 0.5 inches (1.3 cm) in total body length.
- Have black cephalothoraxes.
- Have abdomens in one of two color variations:
- Black with white or yellow spots on the dorsal surface.
- Yellow or gold surrounding black markings (Bradley 2012).

Bold Jumping Spiders Notes
- Bold Jumping Spiders are both powerful predators and one of the largest jumping spider species in North Carolina. They are “intraguild predators”, which means they readily attack other spiders that compete for the same environmental resources, like flies and grasshoppers (Okuyama 2002, https://doi.org/10.1007/s101440200014).
- Look for Bold Jumping Spiders in forests, farm fields, and in and around buildings, especially in the Coastal Plain.
- This species also sometimes enters buildings to hunt insects along window sills (Milne and Milne 1980).

- Bold Jumping Spiders are also called “Daring Jumpers” (Milne and Milne 1980)
