Linyphia triangularis is a species of Spider belonging to the family Linyphiidae.

Distribution
This species occurs in the Palearctic. She was introduced to the United States.

Description
Body: 6mm (5mm for the male).
It is recognized by its large size and the tuning fork mark located on the cephalothorax. with a central on the abdomen and with the indentations as if Ray this band was made of a series of triangles.
The abdomen is whitish with a serrated pattern dark towards the middle.
The legs are grey, Brown or greenish with numerous spines.
The profile view is also quite characteristic.

Habitat
This spider spins his Web in bushes or hedges in autumn, and eat the insects that get caught in its Web. The body of the male is uniformly brownish. (Forests, bushes, parks and gardens.)

Canvas
The canvas is a large net horizontal and little regular. The animal goes in the center of its Web.

Possible confusion:
It differs primarily Neriene genus by the presence of a beautiful pitch drawn on the cephalothorax. However, it has very close cousins l. tenuipalpis and t. maura found in France.
Neriene radiata which is distinguished by a clear Strip surrounding the cephalothorax.
