[Studies on the Sexual Behavior of Cyrtophora cicatrosa (Stolíczka)(Araneae, Araneidae)].

Abstract

Courtship and copulation behaviour of the tropical spider Cyrtophora cicatrosa were observed in the laboratory. They are described and compared with the behaviour of C. citricola. Emphasis is placed on the roles of pheromones and web tapping, and on the species' different ways of overcoming the problems resulting from extreme sexual dimorphism.
