Significant effects are in bold; LCI/UCI: 95% lower/upper confidence intervals from 10,000 bootstraps.

^aCricket mass was originally measured to the nearest 0.1 mg.

^bThe reference density was “high.”

^cThe reference sex was “female.”

^d“Days since eclosion” was centered to mean of 0 and scaled to standard deviation of 1.
