Fig. 1. Depiction of lifting force measurement in this study. Beetles were positioned under a vertically mounted force gauge, using pins on either side of their body (A). The experimenter gently tapped the elytra which stimulated upward lifting. Force readings (B) were obtained over a five-minute period, and the maximum reading was retained for analyses. Further details of this device and procedure are given by (Davis 2014).
