Abstract: Neoconocephalus triops (L.) is a species of copiphorine katydid found throughout southern United States, the Caribbean, and northern South America. It is a single species, not two or more as previously thought. It is the first example of age and of prior adult diapause affecting singing wingstroke rate. It is the first tettigoniid known to break diapause in response to photoperiod and the first orthopteran known to have photoperiod-controlled brown/green color dimorphism. It is the first case of clinal variation in calling song. Furthermore the variation appears to be environmentally induced rather than genetically based. Also it is the first singing orthopteran (perhaps the first insect) whose life cycle is known as it varies from univoltine in the North to nonseasonal in the South. In some intermediate areas, a winter generation gives rise to all of the following summer generation and to some of the following winter generation. The summer generation gives rise to the remainder of the following winter generation. Laboratory studies using live males showed that female; came to calling males. Use of taped calling songs having different wingstroke rates (since they were recorded at different temperatures) suggested that wingstroke rate is important in female attraction.
