SPIDERS

which belong to the non-web-weaving group. We shall attend, 

 in our consideration of the different kinds, first to the spiders 

 which do not spin webs for catching prey. 



Under stones or lurking in half concealment elsewhere on the 

 ground may readily be found certain blackish rather hairy spiders 

 mostly of rather large size. These are the Running Spiders, and 

 they catch their prey by swift running. Their legs are long, the 



hindmost pair be- 

 ing the longest. Some 

 of these spiders have 

 the body, exclusive of 

 legs, an inch or even 

 more in length. One 

 of these large spiders 



may be found, perhaps, dragging after it a dirty white silken 

 ball (fig. 67). This ball is the silken egg-sac which is strongly 

 attached to the spinnerets of the female. The egg-sac is carried 

 about by the spider until the spiderlings hatch. They issue from 

 the egg-sac and climb onto the back of the mother spider, and 

 are thus further carried and protected by the mother until they 

 are able to care for themselves. 



Upon fences, the sides of out buildings, on the bark of trees, 

 or fallen logs, may be found certain small robust, short-legged 

 spiders which move chiefly by sudden leaps. These are the 

 Jumping Spiders (fig. 68). They are 

 usually black, with red or other strikingly 

 colored markings, and two of the eight 

 shining black eyes are much larger and 

 more conspicuous than the others; much 

 larger, indeed, than the eyes of any other 

 spiders of equal size, and they give the 

 Jumping Spiders a peculiarly threatening 

 appearance. These spiders can walk side-
