Procambarus clarkii is a freshwater crayfish species, native to the Southeastern United States, but found also on other continents, where it is often an invasive pest. It is known variously as the red swamp crawfish, red swamp crayfish, Louisiana crawfish, Louisiana crayfish or mudbug

Whatever you prefer to call them, there is hardly an acre of water in Illinois (unless it is the depths of Lake Michigan) or any acre of wet land, where these small freshwater relatives of the lobster are not found. About a hundred species are known in North America, of which a half dozen are abundant in this state.
