The Cesonia genus, including the "stealthy ground spider" (Cesonia species), belongs to the family Gnaphosidae, also known as ground spiders. These spiders are often called “stealthy” because of their elusive behavior and ability to blend into their surroundings. True to their name, they are stealthy hunters that rely on ambush tactics rather than web-building. They actively seek out insects and other small arthropods on the ground.
