Growth rules of the four female types differ, revealing that they are distinct morphological castes.

Column #1: pair of morphological traits for which relative growth rule was assessed (Y vs. X). #2: Pearson correlation test. #3: slope of the regression line (allometry coefficient) and comparison test between female types. #4: comparison of the slope with 1 (isometry). #5: when slopes do not differ between female types, comparison of elevations between female types. Pairs of morphological traits that were not significantly correlated at the same time in three female types were excluded. Thus only eight growth rules are shown out of 21 potential growth rules. Correlations are rarely significant in microgynes due to small sample size.
