argiope aurantia

October 6, 2014 - 3:55pm

A yellow garden spider tends to its dew-laden web.

Argiope aurantia, a.k.a. the yellow garden spider, the black & yellow garden spider or golden garden spider. And while it may be found in your garden as the name suggests, it is actually more at home in any locale where it can suspend its silky web from tall plants and grasses, particularly meadows and alongside narrow, slow-moving streams.  

Its web creations are silky and symmetrical and can measure over two feet in diameter. They are also quite lethal to flying insects. This web, and several others in close proximity, were found in a meadow of milkweed, Queen Anne's lace and dead tansy.

Strung up amid spent tansy and covered with dew, this web bears a certain Halloween motif.

Once her prey is ensnared, this female will "jiggle" her web to further secure her quarry before scurrying across her silky masterpiece and injecting venom into her victim. She will then wrap her prey in a silky cocoon and wait a few hours for the venom to do its work -- turning her victim's insides to liquid. Makes for a high-protein buggy milkshake!
