Quick Summary

Agelena naevia is a species of spider belonging to the family Agelenidae, commonly known as funnel weavers. These spiders are characterized by their flat webs that narrow into a funnel-shaped tube, where the spider hides and waits for prey. They use the front legs to sense vibrations from entangled insects, which are then quickly bitten and consumed in the retreat. Agelena naevia is a common species found in North America, with variations in size and color. The female can grow up to 19 mm (0.75 inches) long, while the male is smaller, reaching up to 8 mm (0.3 inches). These spiders typically live for one year.12
