Yellow Sac Spider
Yellow Sac Spider
Sac Spiders, also known as yellow sac spiders, are wandering spiders that
are found on the ground and other vegetation. These spiders are very small fast runners, with no conspicuous markings. They make their retreat sacs in folded leaves or grass blades, and use their spider silk to weave tent-like sacs between leaves or on tree trunks.
IDENTIFICATION: They are very pale and can be yellow, greenish and tan. The front legs are longer than the rest of their body and legs. Sac spiders are light colored.
