Studies have shown that you're never more than ten feet away from a spider, and one estimate puts you as close as three feet. To be "spider-free" you'd have to go into space in a fumigated capsule. Rather than flee, read these facts and appreciate our amazing arachnids.
Studies have shown that jumping spiders can solve simple 3-D puzzles; they also learn the behavior patterns of other spiders in order to capture them. See more pictures of arachnids.
- Unlike insects, spiders cannot fly--but they can balloon! Young spiderlings pull out silk until the breeze can lift them into the sky. Most don't travel high or far, but some have been seen at altitudes of 10,000 feet and on ships more than 200 miles from land. Most ballooners are very small spiderlings, but adult spiders have been captured by planes with nets.
- Female wolf spiders carry their egg sacs behind them, attached to their spinnerets. After the spiders emerge, they crawl onto the mother's abdomen and hold on while she actively runs and hunts. After about a week, the spiderlings molt to a larger size and then take off to live on their own.
- While most spiders live for one year, a few may have more than one generation each year. Some spiders can live 3 to 4 years, and certain tarantulas are known to live for 25 years or longer.
- Male spiders are almost always smaller than the females and are often much more colorful. Some males are so small that they actually look like they're newly hatched.
