Funnel Weaver Spider (Grass Spider)

Natural Habitat

Often found in grassy areas, gardens, fields, and around human structures. They build distinctive funnel-shaped webs in corners, tall grass, window sills, or leaf litter.

Diet & Feeding

Mainly feeds on various small insects that get trapped in their webs, such as flies, mosquitoes, crickets, and other small arthropods. They are ambush predators.

Behavior Patterns

Funnel weavers are known for building dense, non-sticky, sheet-like webs with a funnel-shaped retreat at one end. The spider typically waits inside the funnel for prey to land on the sheet, then rushes out to capture it. They are very fast runners. They are generally active from spring through fall.

Risks & Benefits

Generally considered harmless to humans. Their bite is rare and typically results in only mild, localized pain and sometimes slight swelling. They are beneficial as they help control populations of various insect pests.
