Kukulcania hibernalis
Southern House Spider
Kukulcania hibernalis, commonly known as the Southern House Spider, is a large cribellate spider native to coastal eastern Mexico and the eastern United States. The species exhibits extreme sexual dimorphism: mature females are velvety black or dark gray with a tarantula-like body shape and lumpy eye arrangement, while males are pale beige or brown with small bodies and extremely long legs. Females construct sprawling, lacy, non-sticky webs around tubular retreats on buildings, using specialized cribellar silk with extreme extensibility achieved through a hierarchical loops-on-loops structure. The species is synanthropic and has been introduced widely across the Americas, the Caribbean, Liberia, and the Canary Islands.
