An unusual system of communication has evolved in green lacewings of the Chrysoperla carnea-group, triggering rapid proliferation of numerous cryptic species across all of the Northern Hemisphere and large portions of Africa. The system is based on sexually monomorphic, substrate-borne vibrational signals, produced by abdominal oscillation. These low-frequency signals are exchanged between courting individuals in a precise duetting format. The song of each of the more than 20 described species exhibits a unique acoustical phenotype that reproductively isolates the taxon from all other species with which it might come into contact. Here, we review what is known about duetting behaviour in the carnea-group, emphasizing the dominant role that duetting has played in the evolution, ecology, and speciation of the complex. Included are descriptions and discussions of song diversity and its impact on reproductive isolation among species, the genetic basis of interspecific song differences, partitioning of acoustic space among sympatric species, parallel song evolution in allopatric species pairs, and modes of speciation within the complex. We also emphasize the importance of correctly identifying by song all species of the carnea-group that are to be used either in experimental studies or programs of biological control, while acknowledging the continuing relevance of morphology to carnea-group systematics.
