A spider web is one of nature's most marvelous wonders. It's art, it's architecture, and it's engineering.
The silk is as beautiful as it is deceiving. It's 10 times stronger than Kevlar; as sticky as cotton candy covered with honey; and as flexible as a classical ballet dancer.
It's also a restaurant of sorts when the sticky strands nab unsuspecting prey. Unlike humans sitting down at a restaurant to order a meal from the menu, a spider never knows what's on the menu until it "magically" appears. It could be a honey bee, sweat bee, carpenter bee, spotted cucumber beetle, ladybug, lacewing, crane fly, another spider or some other critter.
We saw this newly woven wheel web on our front porch this morning. As the sun rose, the web glowed, glistened and glittered. An orbweaver at work..setting the dinner table...
The intricate web made us think of E. B. White's children's novel, "Charlotte's Web." Charlotte, a barn spider, kept writing messages such as "Some Pig" to try to save the life of a pig named Wilbur.
The farmer got the message, but in the real world, the spider's message is not about saving a life, but entrapment.
