Leucauge argyra is a spider and is known for being the host of the Hymenoepimecis argyraphaga, a Costa Rican or Puerto Rican parasitoid wasp.[1] It is found from the United States to Brazil. Leucauge argyra (and many other Leucauge spp.) is known to be a colonial species, with spiders maintaining individual territories/orb webs within a scaffolding of shared support lines maintained by the group. Colonies of multi-generational individuals are often seen with some levels of size stratification (where larger individuals/adults occupy the highest web positions and smaller individuals/juveniles occupy lower web positions).[2]

Description

L. argyra has three lines on the abdomen that run parallel only about halfway across the abdomen, where the outer two bend inward before continuing parallel again through the rest of the abdomen. These markings can be somewhat variable, and different from L. venusta, where the abdomen has inverted V-markings.[3]
