Commonly known as grass spiders, Agelenopsis are funnel web weavers found in grasslands and meadows. They are known for their speed and agility, with long, slender legs. These spiders construct horizontal, sheet-like webs with a funnel-shaped retreat where they await prey.

Agelenopsis, commonly known as the American grass spider, is native to North America. Its geographical distribution extends across the United States and southern Canada. The species is prevalent from the east coast to the west coast, adapting to various local environments.

Agelenopsis spiders typically inhabit grassy areas, gardens, fields, and forests. They thrive in environments that offer abundant vegetation and ground cover. The climate in these regions varies from temperate to subtropical, providing the necessary conditions for their web-building and hunting activities.

Agelenopsis occupy an ecological niche as ground-dwelling predators. They construct sheet-like webs with a funnel retreat, usually near the ground, which helps them capture prey such as insects. The spiders play a crucial role in controlling insect populations in their habitats.
