Wolf Spider
Lycosa (species)
Family: Lycosidae

Habitat and Biology 
  Wolf spiders are ground-dwelling hunters. Some species shelter in permanent 
  burrows while others are vagrants. In the garden they are often encountered 
  by humans whilst digging or weeding. When disturbed they rapidly run across 
  the ground. When they stop suddenly their colour patterns can make them difficult 
  to see. The egg sac is constructed of white papery silk and is carried around 
  by the female attached to her spinnerets at the rear of the abdomen. Upon hatching, 
  the spiderlings are carried around on the female's back until they can fend 
  for themselves. This degree of parental care is unusual among spiders.
