Grass Spider
Agelenopsis pennsylvanica
Grass spiders live in lawns, meadows, fields, and low vegetation, where they build flat sheet webs with a funnel-like retreat at one side. They wait inside the funnel and rush out rapidly when insects vibrate across the web, relying on speed and ambush rather than sticky silk. Their diet is mostly small insects and other tiny arthropods captured on the web surface. A notable feature is the pair of long spinnerets visible at the rear, which help produce the sheet-and-funnel web structure.
