Soliperla campanula .

Sixty-two signals were obtained from two, 3-day old females at 24°C and 60 FTC. Light finger tapping near the recording chamber induced all their answers. The two females produced signals with average individual intervals gradually increasing from 22.4 ms for interval 1 (i1) to 28.4 ms at interval 10 (i10). Total average beat count per answer and overall average intervals were 6.2 ± 2.7 and 25.4 ± 2.5 ms ( Fig. 1 , Table 1 ). There were 8 mode beats per signal and average answer duration was 133.3 ± 73.6 ms.
