Figure 20From: Biodiversity, ecology, and behavior of the recently discovered insect order MantophasmatodeaVibrogram of substrate vibrational signals of two male Striatophasma naukluftense . The specimens were caught at Gamsberg Pass, Namibia (N32); the signals were recorded at ca. 20°C in the laboratory. The male call consists of repeated pulse trains and one pulse train for each individual is shown. The duration of pulse train is about 6000 ms (male 1) and 4500 ms (male 2), respectively. Note the increasing amplitude in the first segment and the more constant amplitude in the second segment of the pulse train.Back to article page
