Agelenopsis sp. (grass spider) is a genus of funnel weavers commonly found across North America in grassy fields, gardens, and low vegetation. They are known for their sheet-like webs with a funnel retreat, where the spider waits to ambush prey. Grass spiders are fast runners, brown to gray in color, and often display two dark stripes along the cephalothorax. Though they may look intimidating, they are harmless to humans and play an important role in controlling insect populations.
