Looking at Debbie Jarve’s web photos here today got me to thinking about how these intricate designs are made and why, so I dug into the world wide web to find more information and this is what I found:

Spiders have a design sense and some webs are extremely intricate for a reason.

Spiderwebs don’t intercept their prey, they attract them.

Spiderwebs are shiny because many insects have better visual perception in UV wavelengths of light and since spiderwebs are much more reflective in UV light, this possibly attracts insects better.

Spiders are sneaky...when you see a web with exoskeletons and egg sacs hanging in it, it could be that the spider left those in the web on purpose as camouflage to protect themselves from predators.

Spiders think big, the size of their webs are carefully designed. Most insects caught by spiders are small, so a larger web increases the odds of catching more flies and possibly larger prey.

Spiders often replace their entire web every single day and they can construct them just about anywhere. The larger the web, the more energy the spider uses to build each web.
A spiderweb sparkling in the sunlight is a beautiful sight, as you can see in Debbie’s photos, but you may be surprised to know that the strength-to-weight ratio of the material is quite remarkable. For more on how strong they really are, check out today’s video from the Science Channel with Mythbusters, Jr. testing the myth that spider silk is stronger than steel.

I have a spider web on my balcony, and I tried to
get pics. Not I tried putting colored
paper behind some pics...not great, and I
broke the web. There's a brand new, bigger one

That vid is amazing! Wow!

I'm super tired of spider webs all over the
front and back porches. It doesn't even pay
to get rid of them because they just build
them again. And as you're trying to get
them, they stick to everything. Not a fan,
though they do serve their purpose.

I remember walking in the late fall beside a field
of tall grass and weeds during a light snowfall. I
was puzzled to see lots of circles of snow suspended
between the stalks. Then it came to me--spiderwebs.

Deb S, I used to feel OK with spiderwebs, because I
saw one in our cabin that had trapped a bunch of
flies. But now I agree with you; they are a lot of
work to clean up.
