Things You'll Need
Instructions
Identify the spider's habitat. This includes the geographic region, such as the southeastern United States, as well as the immediate area, such as a wooded hilly area.
Determine the spider's physical traits. Is its entire body green, or does it have other colors, such as a red thorax? Does it have any spots of different colors? How big is its body? How does it move? Where are its eyes located?
Compare its characteristics to the traits of possible matches. For example, if it is around 16 mm long and moves very fast, it might be a green lynx spider. If it is motionless and camouflaged on a garden leaf, it might be a green crab spider. If it is very small and you spotted it sitting under its web, it may be a mesh web spider.
Compare the spider you saw to identified pictures of spiders in a spider identification book. Find the closest match.
Read the description of habitat and behavior of the spider you think you saw to make sure its behavior matches. Make sure also that the geographical region matches.
