Triangulate Bud Spider
Steatoda triangulosa
The adult triangulate bud spider occupies quiet indoor spaces, sheds, window frames, and dry outdoor shelters where it builds an irregular cobweb. It waits near the web and subdues flies, ants, small moths, and other arthropods with venom delivered through its fangs. Adults are solitary ambush predators that depend on silk, patience, and a fast bite rather than pursuit. The pale triangular markings along the abdomen make this small cobweb spider especially recognizable among household spiders.
