An Untangled Web
Monday, October 22nd, 2007About four or five years ago, I suddenly began seeing a new spider appearing around our yard. The spider itself was small, less than a half inch long, but the webs were large, geometrically precise, and marvelous. Marvelous, that is, unless you happen to walk through one or catch a long anchor line in your hair as you wandered around, minding your own business. The webs, perfect examples of an orb weaver’s artistry, are beautiful, decorated with little tufts of cotton-like balls at intervals. But the spiders themselves are also gorgeous, like little white, red, orange, or yellow jewels, speckled with black dots, adorned with little spikes that have give them the common name of “crab spider.”
They are not, however, true crab spiders, those little yellow and white denizens of my rose bushes and wildflowers. These are Spinybacked Orbweavers, Gasteracantha cancriformis, a species that seems to have suddenly appeared all over the island within the last decade, mostly in the last three or four years. Other common names, according to bugguide.net, include: Crab Spider, Spiny Orbweaver Spider, Crab-like Orbweaver Spider, Crab-like Spiny Orbweaver Spider, Jewel Spider, Spiny-bellied Orbweaver, Jewel Box Spider, Smiley Face Spider, and Crablike Spiny Orbweaver. Quite a list for a half-inch spider.
The Spinybacked Orbweaver is not just any spider, however. In 1999, she (most of the ones you see are female) even had her very own 33 cent U.S. postage stamp as part of an insect and spider stamp series, sharing the limelight with my other favorite arachnid, the Jumping Spider, and one of my least favorites (although, admittedly, rather well-dressed in her patent leather coat), the Black Widow.
