Sometime early this fall, I noticed two cat face spiders living above my front windows. First I discovered their large orb webs, hosting a varied assortment of dead bugs, leaves and as always, dog hair. The spiders themselves spent their days between the exterior bricks and the fascia of the roof. As our exceptionally warm fall progressed, the spiders got bigger and bigger.
I couldn’t ever get a decent photo of them as they generally only came out at night. They didn’t appreciate the camera’s flash – after three or four photo attempts, they would crawl back into their holes.
Each fall, people think their house is being overrun by spiders. What most folks don’t understand is the spiders have been there all summer. It’s not until fall that the spiders have grown large enough to be easily spotted. Most spiders, these cat-faced ones included, aren’t remotely poisonous so should be left to do their job of ridding homes and yards of bugs. They will die once the temperatures drop.
Spiders are not insects, they are arachnids. They are classified in the same phylum as insects and crustaceans because all members have an exoskeleton, or outer skeleton. People, dogs, birds and fish all have internal skeletons.
Make a list or chart that compares an internal skeleton to an exoskeleton. Some headings might include – strength, able to grow, provides protection, segmented. I’ll add an example of a comparison chart next time, but you can make up your own first!
