Tetragnatha is a widespread and very common genus of longjawed orbweavers. 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.

 
             
 
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. This is the feature that gives the family the first part of its common name.

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.

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!
