  • Data organized by congeners. Average temperature 23.4±2.5°C.

    TS, tooth spacing; TD, tooth density; fc, carrier frequency; CWV, avarage closing wing velocity measured with high speed video (HSV); SV, scraper velocity; TSR, tooth strike rate calculated based on (1) CWV and (2) SV. Body measured as the midline from fastigium to last abdominal tergite.

    NA, HSV recordings were not available to measure CWV.

    M. sphagnorum has been included twice because this species uses two modes of stridulation: audio and ultrasonic (Morris and Pipher, 1972).
