Spiders

 According to one of the fact sheets "Most homeowners have misconceptions about spiders-they are pictured to be poisonous (even deadly), and likely to attack at any time. Wrong. The only dangerous spiders we have in Virginia are the brown recluse spider and the black widow spider. The brown recluse is not common in Virginia. The black widow is common, but reports of it biting people are infrequent. For the most part, spiders are beneficial, eating insects and other spiders."

The brown recluse spider has what appears to be a fiddle or violin on it's back.  The black widow has what appears to be an hour glass on it's stomach.
