Although \u0000light is the primary cue for initiating and maintaining swarms, chemical cues such as sex pheromones may help \u0000maintain individuals in a swarm. A behavioral repertoire for mating was determined in the laboratory( Males \u0000briefly contacted other animals to identify potential mates. Males displayed more mating behaviors with and \u0000only placed spermatophores on virgin females.

Mating only occurred in laboratory swarms composed of males and virgin females. \u0000Pairs displayed distinctive behavior of sinking during mating followed by bursts of rapid swimming. These \u0000mating pairs may be more vulnerable to predation because of their swimming pattern.
