They are very common in the eastern U.S. and Canada.
They live in gardens and shrubberies and in homes.
They are small spiders. The females are larger than the males at more than 1/2 inch long. They have 8 eyes and very good vision for hunting. They have 4 big eyes on the face and 4 small eyes on top of their head. They are very hairy. The abdomen has some white spotting. The mouthparts are shiny green. They have powerful back legs for jumping. They pounce on prey.
They do not build webs, but do use their silk to build places to hide in the foliage and bark of trees. They are active during the day (diurnal). They will bite if disturbed. They are skilled hunters, sneaking up and pouncing on prey. They dangle a line of silk to catch them if they miss prey.
They eat other spiders and insects.
The female lays eggs in an egg sac under a silk blanket. She will guard the egg sac and newly hatched spiderlings until they are able to be on their own.
