Spiderswhat’s this spider?
Dear Bugman:
Here’s a Black-and-yellow Argiope, Argiope aurantia; her prey item is an odonate, probably a male Pacific Forktail (damselfly).
? Now my question: Can you ID this other female, possibly also of genus Argiope? ? These two are common in the Bay Area of N California. I refer to the second as a "Banded-legged Argiope," although it could be in a related genus. Its habits and life cycle are similar to the Black-and- yellow. Curiously, this one has a pattern on the underside of the abdomen that virtually duplicates that on the back of the B&Y.
thanks,
Odophile

Dear Odophile,
Common names can sometimes duplicate for different creatures, and they can also vary from locale to locale. Your Black and Yellow Argiope also has other common names like Golden Orb Weaver, Yellow Orb Weaver, and Black and Yellow Garden Spider, but they are all Argiope aurantia. Your Banded Legged Argiope is an Argiope, and is commonly called the Banded Argiope, Argiope trifasciata.
