Phidippus audax are black with three marks on the abdomen. When they are young, the three spots on the abdomen are of orange color. As they grow older, those markings will turn white. The abdomen is larger than the cephalothorax. It can easily be mistaken with a male Regal Jumping spider that has a very similar appearance and markings.

The legs are short for spiders and it uses its back legs for its jumps. The spider suddenly increases blood pressure in the back legs which catapults it towards its destination.

They have eight eyes. Four across the front and two along each side. The two middle eyes in the front are much larger than any others.

The most telling feature to distinguish the Daring Jumping Spider from other Jumping Spiders are the fangs. The Daring Jumping Spider’s chelicerae has a green metallic coloring.

Size

The Daring Jumping Spider will grow to about 3/4 inch (19mm).

Web

Being hunters, the only time the daring jumping spider spins a web is just before the jump. They will attach a drag-line to the surface it is jumping from in case the jump fails. And sometimes the create webs as pup tents at night to rest in.

Bites

Jumping Spiders usually will run and hide rather than attack a human, but there are cases where people do get bit. They get listed in the little to no risk category. However, there are cases of the bites causing pain and significant swelling. The more serious, but rare cases can cause headaches, fever, chills, nausea and vomiting that can last a few days.
