Found throughout the United States and Canada grass spiders can be seen from spring to fall on their tunnel like webs in plants and shrubs. These non-aggressive spiders spend most of their time waiting for flies and other insects to get tangled in their webs. They are fairly easily identifiable, a small brown spider with longitudinal striping on their legs. Male grass spiders usually spend most of their adult life wandering in search of a mate. Shortly after mating, the male often dies. Females however, do not wander from the web, and if they do, it is typically to find a new location to build the next web. They spend most of their time capturing and eating prey, building up their strength to mate and lay eggs, and wait for males to wander by and find them. In the fall, after mating, the females will deposit a disc-shaped egg sac in a crevice, and then die - often still clinging to the egg sac.
