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]
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.

Perhaps the most famous group of spiders that construct funnel-shaped webs is the Australian funnel-web spiders. There are 36 of them and some are dangerous as they produce a fast-acting and ...
A. aperta are funnel weavers, which are known for their characteristic funnel-shaped webs. These webs consist of a flat surface that is connected to a deep tube, which is known as the funnel. The spider waits in the tube, and when it senses motion on the flat sheet of its web, it emerges from the tube to catch its prey.

The spider sits at the back of the funnel shape, waiting for prey to disturb the web.

The spider will rush out and attack the prey item, dragging it back to the back of the funnel to consume its meal.
