stretch spiders

(Tetragnatha spp.)

Overview

Tetragnatha is a widespread and very common genus of long-jawed orbweavers that is commonly known as stretch spiders. It occurs on every continent except Antarctica. There are currently 320 recognized species worldwide but as few as 17 species in North America north of Mexico. Eleven species have been recorded in Minnesota. Larger species are found near water in marshes and shrubby wet areas, on the banks of rivers and streams, and on the shores of lakes and ponds. Smaller species are found in fields and meadows.

Tetragnatha spiders construct a flat, circular web on a single plane which may be tilted or almost horizontal. This orb-like web is the feature that gives the family Tetragnathidae the second part of its common name. They conceal themselves by stretching out along a twig or blade of grass, virtually disappearing, and holding on by just their third pair of legs. This is the feature that gives the genus its common name.

Many sources use the common name “long-jawed orbweavers” for the genus Tetragnatha. However, that common name is already used for the family Tetragnathidae.

Description

Tetragnatha is a small to medium-sized spider. Females are 3 16 to (5 to 15 mm) in length not including their legs. They have a 1 to 2 (25 to 50 mm) legspan. Males are much smaller, to 5 16 (4 to 8 mm) in length. The body is long and narrow, 2.5 to 5 times longer than wide, sometimes wider near the base. The front part of the body (carapace) may be yellow, tan, or reddish-brown. The abdomen varies from pale tan to dark brown, often with dark markings above. The legs are long and slender. The first, second, and fourth pairs of legs are very long, much longer than the body. The jaws (chelicerae) are very long, as long as the carapace in some species.

The cylindrical body, very long legs, and very large chelicerae make it easy to identify this genus. Determining the species is much harder, and even experts often limit their identification to the genus level.

Glossary

Carapace

The hard, upper (dorsal), shell-like covering (exoskeleton) of the body or at least the thorax of many arthropods and of turtles and tortoises. On crustaceans, it covers the cephalothorax. On spiders, the top of the cephalothorax made from a series of fused sclerites.

 

Chelicerae

The pair of stout mouthparts, corresponding to jaws, in arachnids and other arthropods in the subphylum Chelicerata.

About

Published on May 26, 2018

Long-jawed Orb-weaver Spiders, sometimes called Common Stretch Spiders spin an orb web to catch their prey. They're usually found in vegetation close to ground level and frequently close to water. The elongated body can vary in colour from creamy-yellow to green or pale brown. The legs are a yellow-brown colour.

About

Aug 18, 2020

These Tetragnatha versicolor spiders can actually walk on water easier than it can walk on land. In this video, I'm showing you how they walk/swim on water. It's no wonder these are always found building horizontal webs right over water. This was recorded at 6 Mile Waterworks/ Rensselear Lake in the Albany Pine Bush Preserve. Thanks for watching!
