    Long-Jawed Orb Weaver - (Tetragnatha spp.)

    Long-Jawed Orb Weavers have big mouths, but make no noise. They hang up-side-down, silently waiting for a meal to drop in.




    Staff Writer (1/24/2017): The Long-Jawed Orb Weaver has an incredibly long set of front of legs. The female's mouth part, the chelicerae, is also unusually long as well. Males have a very short chelicerae.

    This spider weaves a small, horizontal web between the stems of a plant or shrub. It lies in wait on a stem, vertically, with its front pairs of legs stretched before it and its hing pairs of legs wrapped around the stem. The spiral web has a hole in the center. Any disturbance will cause the spider to descend.

    Females lay their egg sac nearby in a silken cocoon. Once hatched, the spiderlings disperse and weave their own webs on other plants.
