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

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.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
