Spiders
All spiders feed on insects or other arthropods and are beneficial
in the garden.
Spiders are classified in the arachnid group along with mites, and
are very common invertebrates. Unlike insects, which have six legs
and three main body parts, spiders have eight legs and two main body
parts. Spiders try to avoid people and most are harmless to humans.
All spiders are predaceous; they eat mainly insects, other spiders,
and related arthropods. Some species capture prey in webs and others
stalk insects across the ground or vegetation and pounce on them.
About 50 families of spiders occur in the U.S.
