Phidippus johnsoni
(Red-backed Jumping Spider)

These red-backed jumping spiders are common in this area and can often be observed hunting in the meadow or your backyard. These colorful jumping spiders were captured separately, but in the same week in April of 2002. When put together, the male was friendly, but the female wasn't. It was interesting to watch them dance and display their iridescent chelicerae and fangs to each other as they "dosadoed." Perhaps the female noticed that the male had lost a leg and thought she could do better.

The spiders were placed in a
not-so-clear plastic container.

Notice the fang? These spiders can cause a painful bite.
