I like spiders. This is almost certainly linked to my early childhood experience of being shown first hand how they eat. My father used to put captured grasshoppers and other bugs in the web of a gardener spider in our yard. We got to watch the capture, the bite to stun the prey, the wrapping up of the prize, and the slow feeding on the hapless victim.
Spiders are our friends. We spray tons of insecticide, buy fly paper and bug zappers, hire exterminators, and use copious amounts of insect repellent. Here's a creature that will gladly dispose of all the nuisance insects for free.
Watching web construction is another fascinating pasttime. The patient task of spiralling around and around in ever tightening circles to complete the pattern is something to watch.
Scientist have noted that, "pound for pound" spider silk is stronger than steel. Many have sought to copy the procedure that the spider uses to make webbing. National Geographic had an excellent article on spiders some time back, complete with an awesome illustration of the web silk glands. These glands are in a cluster and the spider can make a variety of silk, from fine to thick, non-sticky to sticky. I knew there was variety because when they wrap prey it comes out in a net rather than a single strand. They make parachutes, fine jump lines, and egg casings all from the same material.
This summer has been thick with what we always called orb weaver spiders. In researching for this blog, I found the wikipedia page http://en.wikipedia.org/wiki/Araneidae which seems to indicate that Orb Weaver is a family of spiders, all the ones with elaborate webs. There is a picture of the species Eriophora transmarina on this page, which is similar in shape to the spider I've always thought of as the Orb Weaver, but it's lighter in color and lacks the two white spots of my local friends. The coolest thing about this spider is that it manages to place webs in really improbably places, like out in the open between trees, where you realize that the web spans 20 or 30 feet across.
The attached picture is too blurry to be satisfactory, but I took dozens of photos on two different occasions of the spider and not one came out in focus. I'll have to work on that. I'd like to identify the species, now that I see that there are hundreds of spiders in the family.
I listen to a podcast called "NPR: Driveway Moments Podcast". The 9/5/08 episode was about Charlotte's Web. I vaguely remember details from the book, having read it when I was very young. Everyone who has read it remembers the broad outline, the spider saves the pig by weaving words in the web over it's sty. E.B. White read the audiobook version of the book and had to redo the part where Charlotte dies several times because it made him cry each time he read it. The producer said it took him 17 takes to read that part. He remarked afterwards "It's ridiculous. A grown man, reading a book that he wrote, and being unable to read it aloud because of tears." They say that children take the death of Charlotte better than children for some reason.
Wouldn't it be a nicer world if we felt just a little more that way about the death of any of our animal friends?
