Many black spiders exhibit white markings, such as the white-spotted jumping spider, the gray wall jumper, grass spiders, the zebra jumper and the false black widow. Others can be researched using resources like online arachnid identification sites.
The spiders listed above live in a range of environments across North America, spanning from urban areas to forests, and are not poisonous. Many of the jumping spiders are considered to be curious arachnids and use the jumping adaptation to hunt bugs and other prey, according to the Missouri Department of Conservation. The false black widow is related to the deadly black widow, but is not harmful. It boasts a similar build, but lacks the red belly marking.
