Triangulate Cobweb Spider

Found globally in temperate regions, commonly indoors in dark corners, basements, and cellars, as well as outdoors under rocks, logs, and bark.

Carnivorous. Feeds on various arthropods, including other spiders (even potentially dangerous ones like brown recluses), ants, and common household pests.

Builds a messy, irregular cobweb in protected areas. They are nocturnal hunters that rely on vibrations in their web to detect prey, which they then wrap securely in silk before biting.

Benefits include pest control by reducing populations of household insects and other spiders. Risks are minimal; their venom is not medically significant to humans, though a bite may cause mild localized pain or irritation similar to a bee sting.
