Insect Order (Araneae)
ARANEAE (SPIDERS)
Araneae, comprising spiders, are one of the most intimidating orders of insects to the casual observer. This predatory group is made up of roughly 3,400 species in the United States and Canada. Some are webspinners while others are not, and some are completely harmless (and beneficial) while others are not. Classic examples of spiders include garden-loving Orb Weavers, the common House Spider, the identifiable Black Widow, the mighty Wolf Spider, and the venomous Brown Recluse. Eight legs typically differentiate Araneae insects from other orders.
