Distribution of the duration of tonic immobility in males of Gnathocerus cornutus. (IMAGE)
Caption
The black-filled bar shows beetles that did not exhibit tonic immobility. The straight lines in the beetle illustrations indicate the mandible length (a) and prothorax width (b). Many beetles had shorter durations, while a few had longer durations (range 0-563.31 s, mean ± s.d. = 58.44 ± 73.27 s).
