The spider pictured here is approximately 6 mm. long.
She was photographed on a tuft of cotton.

The grass spiders are members of the Genus Agelenopsis. They weave sheet webs that have a funnel shelter on one edge. The web is not sticky, but these spiders make up for that shortcoming by running very rapidly. They may be recognized by the arrangement of their eight eyes into three rows. The top row has two eyes, the middle row has four eyes, and the bottom row has two eyes (spaced wider than the ones on the top row). They also have two prominent hind spinnerettes, and somewhat indistinct bands on their legs.
