Bold Jumping Spider

Bold Jumping Spider Introduction

Phidippus audax is a common jumping spider of North America. It is commonly referred to as the daring jumping spider, or bold jumping spider. The spider belongs to the genus Phidippus, a group of jumping spiders easily identified both by their relatively large size and their iridescent chelicerae (mouthparts). Like other jumping spiders, due to their large, forward-facing eyes, they have very good stereoscopic vision. This aids them when stalking prey, and allows some visual communication with others of their species, such as courting ‘dances’. Jumping spiders are compact in shape with short legs. They are usually black in color with pale markings. Jumping spiders build web retreats, which can be found both indoors and outdoors. These spiders frequently hunt inside structures around windows and doors because more insects are attracted to these areas and their vision is best in sunlit areas. Outside, jumping spiders are commonly seen running over tree bark, under stones and boards, and on bushes, fences, decks and the outside of buildings. Unlike most spiders, jumping spiders are active during the daytime and seem to like sunshine. They have the keenest vision of all spiders and are able to detect movement up to 18″ in distance. Adult males range from 4–15 millimeters in body length, with an average of 8 mm. Adult females range from 4–18 millimeters in body length, with an average of 11 mm. They are common in fields and grasslands, and are frequently seen on fences, exterior walls, and gardens as well. Many jumping spiders seem to prefer flat vertical surfaces, likely because it enables them to spot and chase down roaming insects with ease.

Bold Jumping Spider Fun Facts for Kids

  • # 1. Jumping spiders may bite in defense, but their bite is not venomous.
  • # 2. Careful, this species can look remarkably similar to some regal jumping spiders; the adult males of the two species are almost inseparable, except by the experienced eye.
  • # 3. In adult males, the front pair of legs are the thickest and have long, conspicuous tufts of white and black hairs.
  • # 4. When a jumping spider wants to soar, it contracts special muscles to increase the flow of blood to its legs. This makes the legs fully extend and sends the spider flying — sometimes as far as 50 times the spider’s body length.
  • # 5. Silken egg sacs are attached under rocks or tree bark, old logs, or in other crevices, and the female stands guard over it. Each brood may have anywhere from 50-200 orangish eggs within it.
