They are best known for the circular webs, called orbs, that they build. Orbweavers are found in woodlands, fields, and caves on grasses, shrubs, and trees and on buildings and fences. ![]() There are 3,067 currently recognized orbweaver species in 177 genera worldwide, 180 species in North America north of Mexico, and at least 44 species in 16 genera in Minnesota.
