Survival and post-mortem measurements
Following the end of the two-night calling trials, males were returned
to their original individual rearing boxes and provided standard diet
and water ad libitum . Mortality was monitored and recorded daily.
Upon death, pronotum width was measured as a proxy for structural body
size, using a stereomicroscope (Nikon SMZ800) equipped with a digital
camera and imaging software (Nikon NIS-Elements Documentation v. 4.20).
