Spiders are technically not insects, because spiders have eight legs and insects have six. If you can get over your fear of spiders, then you'll be able to appreciate them from a natural design perspective. Their patterns and colors rival those of butterflies, except that spiders are predators and a few such as the female Western Black Widow Spider have poisonous bites that can be fatal to humans.

Looking for spiders is like going on a scavenger hunt since they can be difficult to find in well-maintained urban settings. Aside from natural predators such as birds, larger spiders, and certain wasps, there are pesticides, vigilant landscape keepers, and fearful humans taking a toll on their numbers though spiders eat many harmful insects.

There are hundreds of species of spiders in North America. Orb weavers are the most conspicuous because of their large webs. (Cool picture of a fossilized orb weaver that lived 100 million years ago.) I did my best to identify the photos using the following references.

Trashline Orb Weaver, Cyclosa conica, FAMILY ARANEIDAE: This spider can be difficult to see because it conceals itself in a vertical trail of debris (web decorations called "stabilimenta"), but generally the spider can be found at the center of the web. Note the cone-shaped extension of its abdomen.

It was very protective
of its food and carried
it away as I watched.

It was amazing watching this spider create its web in the early evening. Its contortions reminded me of a mountain climber trying to find stable hand and foot holds.
