Agelenopsis aperta
Desert Grass Spider, Funnel-web Spider
Agelenopsis aperta, commonly known as the desert grass spider, is a medium-sized funnel-web weaver native to arid regions of the southwestern United States and northwestern Mexico. It constructs characteristic non-sticky funnel-shaped webs in crevices and vegetation, where it waits to ambush prey. The species exhibits notable territorial behavior and complex courtship rituals involving abdominal swaying and pheromone release that induces a temporary cataplectic state in females.
