Spiders usually reproduce in the summer or early fall. Whenever possible, natural enemies are used to combat pests instead of pesticides. That is the advice given by Poison Control in Arizona. Probably the most important feature of the arthropods in their exoskeleton, a complex rigid outside covering that gives the muscles something to pull against.

The fossil record of pseudoscorpions dates back over 380 million years, to the Devonian period, near the time when the first land-animal fossils appear. Hard shells (or hard parts) are one of the features that make an organism a better candidate to become a fossil. Yes, there has been evidence of spider web trapped in amber from the cretaceous period so they would have been around during the ice age as well.

Camel spiders shun the sun and generally hide during the day, coming out at night to do their hunting. Tarantulas typically hide during the day in burrows or dark holes. Clearly laid out in sections by topic--arthropods, exoskeletons, eyes, wings, camouflage, etc.--this book is engaging and thorough. Bacterial infection of the wound caused by Mycobacterium ulcerans carried on the fangs of the white-tail spider, may be a contributory factor. Their invention is millions of years old and has stood the test of time.
