Spider web Photos
Monday, May 7, 2007
When we were at the Nursery a couple weeks ago we found some great peppers. This Tomatillo looked so cool I just had to grab him too. I figure they'll make some good salsa together too. I just got a great book of salsa recipes for my birthday and I can't wait to try it out!

Web of Dew
There are a lot of spiders around here but they sure make some beautiful creations. I always wondered how the drops stayed on the web. I always thought they should just run down to the lowest point and drip off. Took a little research but the answer is really interesting.

Web of Dew
This was a great rainy morning. The drops of dew made a great subject to experiment with depth of field. An interesting subject in other ways too, an earlier image of the day gave me the opportunity to learn more about these amazing structures.

Dew Drop Web
One of the things I like about taking my images one at a time and
preparing them for this site, is the opportunity
it gives me to think a little more about each subject. When I saw this web
I took an entire roll of film because of the beauty of the dew, like pearls
on a string. Now, while preparing it for the site, I started to think
about why the drops of dew stayed there. The water should run down to the
lowest point, collect and drip to the ground but the web is covered with it.
I realized that not all of the web was sticky, the spider walks on the radial threads, which are not sticky. The concentric threads are where the sticky part is. (Apparently it is even more complex than that, There are seven different kinds of silk that spiders can spin but that is a little off topic.) The interesting thing about the sticky thread is the fact that the sticky comes from small drops of liquid on the silk. These small drops make an imperfection on the slick silk that the drop of water can hang on. Which also explains my next thought about the water, why is it so regularly spaced? Because the spider places the sticky drops evenly.
Of course, the trouble with that explanation is the fact that there are drops on the radial threads in this photo, albeit not as large and not as many. Perhaps there is some stickiness to all of the strands on this particular type of spider web? Or just other imperfections in the strand? Perhaps specks of dust?
