Intraspecific communication was unaffected when an area of microtrichia associated with a possible stridulatory structure was excised from the wing of a sexually receptive C. carnea male. Additionally, no high-frequency audio sounds were detected by analysis of oscillographs; however, males and females of C. carnea and C. downesi responded to recordings of conspecific calls when the low-frequency oscillations were transmitted to a compliant substrate and when all high-frequency information was filtered out. Therefore, exchange of low-frequency substrate oscillations is sufficient for intraspecific communication in the lacewing species studied. Evolutionary implications are discussed briefly.</p>
