Spider behavior

The behavior of spiders is an often neglected topic in the study of arachnology, stemming from the fact that it is much easier to collect dead specimens for later examination than to observe them in their often inaccessible habitat, or to create laboratory conditions suitable for the observation of natural behavior.

Hunting

Many spiders, but by no way all, build webs. The bolas spiders use a sticky globule, together with a pheromone analogue, to catch moths. Jumping spiders, and many other types of spiders as well, hunt freely. Some of these have enhanced eyesight, sometimes approaching that of a pigeon (although with a much smaller field of vision).Some spiders hunt other spiders; the jumping spider "Portia" mimics the movement of captured insect prey to attract web building spiders, and then overwhelms them.

=Reproduction=. Other arachnids may reproduce asexually or sexually. This is seeing as their class makes up 3% of the animal kingdom. The female tends to eat the male. They behave by running around on trees and in bushes and in tightly packed areas so they stay distracted from the others around them.
