The Long-Jawed Orb Weaver may have a big mouth, but it silently waits for a meal to drop in before opening it.
The Long-Jawed Orb Weaver has an incredibly long set of front of legs. The female's mouth parts are also unusually long as well. Males have shorter mouth parts. The brown spider is often spied with its front pairs of legs stretched before it, a posture not seen in many types of spiders. This spider weaves a small, horizontal web between the stems of a plant or shrub. The spiral web has a hole in the center. It lies in wait on a stem, with its hind pairs of legs wrapped around the stem. Any disturbance will cause the spider to descend.
Females fill their flat, brown egg sac with fertilized eggs and place it nearby, wrapping it in silk. Once hatched, the spiderlings disperse and weave their own webs on other plants. Many species of Long-Jawed Orb Weavers prefer to live near water, but there are some that thrive in drier areas, like among pine trees.
Scientific Name: Tetragnatha spp.
Size (Adult; Length): 5mm to 12mm (0.20in to 0.47in)
Note: 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 as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
Pedipalps: Small appendages near the mouth used as taste and smell organs.
Cephalothorax: Contains eyes, head, mouthparts, and legs.
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
Spinnerets: Used in the production of spider silk for fashioning webs or catching prey.
NOTE: Unlike insects, spiders have both an endoskeleton (internal) and exoskeleton (external).
