The enormous Giant Crab Spider is an ambush predator usually found hanging out on walls, waiting for insect prey to pounce on.





The Giant Crab Spider is also known as the Golden Huntsman Spider. This is one of the largest spiders in North America with its body fitting in the palm of the hand - not including the legs!

They are ambush predators, lying in wait on vertical surfaces for anything smaller than itself. They have been seen on tree trunks, shrubs, boulders and other objects that lend height and offer a surface to hold onto like the sides of houses, and sometimes are even found inside homes. They are most comfortable in arid, desert regions.

Adults are most active and visible in summer months. Females are larger than males. They spin silken egg sacs that they fill with fertilized eggs, guarding the eggs until the spiderlings hatch a month or so later.
