Jumping spiders can be black, brown, or gray in color with white, gray, yellow, red, blue, or green markings. They have a furry, compact body with relatively short legs. Despite their short legs, they have the ability to jump up to 20 times their body length. Unlike most spiders, the jumping spider is active during the day. They may be found indoors underneath furniture, in drapery, on bookshelves, around door or window molding, etc. Outdoors, they are found under loose bark, between leaves, under stones, on decks, etc.
