Yellow Sac Spider

Description:

At night, sac spiders actively hunt their prey—usually small insects. In search of prey, they run quickly waving their forelegs before them. Indoors, they can be observed on walls and ceilings, but drop to the floor to seek cover when disturbed. When I was trying to take it's picture ,it dropped a strand and lowered itself to the ground.

Habitat:

on dryer.
