  1. All recordings were made at 26°C. Species are presented in ascending size order
  2. n, number of recorded individuals per species with 50 sounds analysed per individual. Thus, the standard deviation was sometimes calculated from 300 measurements (in case of 6 recorded individuals per species) or from 50 measurements when only one specimen per species was recorded.
