Grass Spider
The American 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 larger specimens (depending on species) can get up to approximately 19 mm in body length. 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 spinnerets, and somewhat indistinct bands on their legs. They also have two dark bands running down either side of the cephalothorax.
Agelenopsis aperta, the American funnel-web spider, produces agatoxins. Their bite causes rapid paralysis in insect prey, although the spider's Chelicerae are too small to penetrate human skin.

Famous quotes containing the words grass and/or spider:
“The human head is bigger than the globe. It conceives itself as containing more. It can think and rethink itself and ourselves from any desired point outside the gravitational pull of the earth. It starts by writing one thing and later reads itself as something else. The human head is monstrous.”
—Günther Grass (b.1927)
“But chief to heedless flies the window proves
A constant death; where gloomily retired,
The villain spider lives, cunning and fierce,
Mixture abhorred! Amid a mangled heap
Of carcases in eager watch he sits,
O’erlooking all his waving snares around.”
—James Thomson (1700–1748)
