Agelenopsis, commonly known as the American grass spiders, is a genus of funnel weavers described by C.G. Giebel in 1869. [1] They weave sheet webs that have a funnel shelter on one edge. The web is not sticky, but these spiders make up for that by running very rapidly. The larger specimens (depending on species) can grow to about 19 mm in body ...
Agelenopsis pennsylvanica, commonly known as the Pennsylvania funnel-web spider or the Pennsylvania grass spider, is a species of spider in the family Agelenidae. The common name comes from the place that it was described, Pennsylvania, and the funnel shape of its web. [1] [2] Its closest relative is Agelenopsis potteri. [1]
Desert grass spiders' cephalothorax and abdomen together are usually 13–18 mm long. [2] Females are larger in size than males, as is common in all grass spiders. [3] Desert grass spiders have prominent spinnerets, which are the organs that make silk for spiders' webs. Their spinnerets are long and extend out of the end of their abdomen.

The Agelenidae are a large family of spiders in the suborder Araneomorphae.Well-known examples include the common "grass spiders" of the genus Agelenopsis.Nearly all Agelenidae are harmless to humans, but the bite of the hobo spider (Eratigena agrestis) may be medically significant, and some evidence suggests it might cause necrotic lesions, [1] but the matter remains subject to debate.

Black widow bites come primarily from adult female spiders, and especially those protecting an egg sac, Penn State Extension notes. ... Wolf spiders (Lycosidae species) and grass spiders ...
Agelenopsis actuosa (actuosa = "active, agile") is a species of grass spider found in southwest Canada and the northwest United States. [1]The species are rather similar to those of the genus Agelena, instead of Agelenopsis, mainly because of their paler coloring and the meeting of the two lines on the cephalothorax (near the abdomen) [citation needed], which are usually parallel in other species.
Argiope catenulata, also known as the grass cross spider, is a species of orb-weaver spider (family Araneidae) ranging from India to the Philippines and Papua New Guinea, and also found in Australia in 2019. [1] [3] Like other species of the same genus, it builds a web with a zig-zag stabilimentum. [4]
