JUMPING SI'I I >KRS. .(/'/ 



The jumping spiders make no webs to catch their prey, but spin nests in some crack or bark of a tree 

 to use over winter, or for changing their skins. They also, when jumping, throw out a thread to avoid 

 falling. They can walk easily sideways or backwards and can jump (]iiite a distance. Their eyes are in 

 three or four rows, those in the middle of the lowest row being the largest; those of the row before the 

 last sometimes almost invisibly small, and the last row placed far backward, nearly half the chest part. 



Besides their eyes, their long square bodies and short legs and impudence make these spiders easily 

 recognizable. The length of their legs vary; in some kinds the first pair, in others the fourth, the second 

 and even the third are the longest. In some kinds the first pair of legs are much stouter than tin- othi i 

 Some kinds resemble ants closely in shape and actions; they even walking on six legs by stretching out 

 one pair like feelers. 



In Sa/fic/is the last row of eyes is as far from the row before the last, as the eyes in this row are from 

 each other. In Attns they are not half that distance apart.
