Kaira is a mostly neotropical genus of orb-weaving spider with 16 described species. They occur from South America up to the southern and eastern USA.They spin small webs from which they hang upside down and attract male moths that fly into a basket formed by their legs. They use a moth pheromone for this which resembles the one used by the Bolas spiders Mastophora. The two genera are not closely related although they belong to the same family.
