Spiders of the genus Clubiona, commonly called leaf-curling sac spiders, can be found throughout the world and in every US state.
Clubiona Description
Clubiona spiders usually have light-brown legs and cephalothorax and a slightly darker abdomen. Their legs and head may even appear transparent at times due to the light color.

Bite
