Common House Jumping Spider
One of the most common jumping spiders found in homes in North America is the daring jumping spider (Phidippus audax). Adults rarely grow larger than 2 cm. Some common house jumping spiders appear black with white markings along the abdomen, while others are iridescent and feature metallic green chelicerae.
Jumping spiders are particularly abundant in grassland and prairie environments, where they prey upon bollworms, cotton leaf worms, webworms, cotton flea hoppers, stinkbugs, leafhoppers and mosquitoes. Jumping house spiders also enter indoor habitats by being accidently carried in on plants or a person. These arachnids can be found in yards, as well as inside and surrounding barns and houses.
