Ant-mimic spider (specifically a member of the Castianeira genus)

Typically found in leaf litter, under rocks, or on low vegetation in gardens, forests, and grassy areas; they occasionally wander into homes.

Strictly insectivorous; they hunt other spiders and small insects like flies and ants by active pursuit rather than building webs.

They are diurnal hunters that mimic the appearance and movements of ants or wasps to avoid predators and sneak up on prey. They do not spin webs for catching food, but use silk only for egg sacs and retreats.

They are beneficial garden predators that control pest populations. While they are venomous (all spiders are), their bite is generally not considered medically significant to humans, though it may cause localized pain and swelling similar to a bee sting if handled roughly.
