Silver Argiope

Description:

Photo take near home in a path this big spider working hard enfold a June Beetle. about 7cm wide x 7cm long. These orbweavers place a conspicuous zigzagging white silk banner in their webs called the "stabilimentum" which can be used to identify the species. In this species four stabilimenta form a cross in the web of mature spiders. Juveniles of many species, including this one, spin a spiralling stabilimentum from the center of the web. The function of the stabilimentum is not fully understood. Hypotheses are; that it stabilizes the web, or makes it more apparent to birds which will thus not fly into and wreck it, or it reflects light to attract insect prey, or perhaps most likely helps to camouflage the spider in the web.

Habitat:

Garden orbweavers rebuild their webs each morning in their typical habitat, field edges, open woods and gardens
