The bolas spiders (Family Araneidae, several species in the North American genus Mastophora and the Australian genus Celaenia)are known to produce a pheromone analog that attracts male moths of a few species in the family Noctuidae. The moths are trapped on a sticky ball on the end of a silk line (the bolas). Other non-web building araneids, such as those in the genus Kaira (which does not use a bolas), may also produce pheromone analogs. See: Eberhard, W. G. 1977.
