Triangle Web Spiders, Triangle Spiders
Hyptiotes is a genus of small cribellate spiders in the family Uloboridae, commonly known as triangle web spiders. These arachnids are distinguished by their unique triangular webs—rudimentary orb webs consisting of four radii connected to a single anchor thread. They are notable as the only spiders in North America that lack venom glands, relying instead on specialized silk to capture and subdue prey. Adult females measure 3-4 mm, while males are 2-3 mm. Four species occur in North America, with three primarily western and one eastern species (H. cavatus).
Hyptiotes puebla
triangle spider
Hyptiotes puebla is a species of cribellate orb-weaving spider in the family Uloboridae, commonly known as triangle spiders. Like other members of its genus, it constructs a distinctive triangular web that represents a reduced sector of a typical orb web. The species occurs in the United States and Mexico. As a uloborid, it lacks venom glands—a unique characteristic among North American spiders—and relies on specialized silk capture mechanisms to subdue prey.
