Figure 4.Oscillograms showing the drumming call of an Isoperla claudiae sp. n. male (ambient air temperature 24.2 °C). A oscillogram showing rhythm and amplitude variation patterns of a call B a faster oscillogram of two bi-beats from the second half of the call C variation of interval duration between bi-beats during the call presented in A. Inter-beat intervals were measured from the amplitude peak of one bi-beat to the amplitude peak of the next bi-beat (measured on the same call presented in A).
