Flea jumper

Flea jumper

Naphrys pulex

A species of Naphrys

The flea jumper (Naphrys pulex) is one of the four largest species of jumping spiders in North America. As a result, it may seem pretty menacing, but the only jumping you'd see in relation to yourself is jumping away. Instead, using their impressive eyesight, they jump on prey that is located at a distance. They like to spend time on the bottom of hardwood forests with plenty of leaf litter.

Toxic to Animals

Flea jumper typically delivers mild venom through a bite with its fangs. This organism has developed a toxin that is mostly a concern to smaller animals such as lizards and frogs, but may also affect humans with various levels of discomfort. Flying insects, like bees and flies, often become prey and are more severely affected due to the toxin's function in predation. Adult flea jumper use their venom to successfully hunt and deter potential threats, rather than causing significant harm to large animals.

Bite Humans

Flea jumper is not characteristic of biting humans. If contact occurs, it could be for defense. Such interactions are rare, with no significant effects on humans. Flea jumper typically employs no methods targeting humans, as this behavior is not a natural aspect of its life cycle or predatory instincts.
