Table 4.

Parameter estimation of Generalized Linear Model (Poisson distribution) for modeling the total reproduction of wild-caught fruit-feeding butterflies held in captivity on sugar or banana diets, where E. medon fed sugar is treated as the baseline group. Overall, butterflies fed banana laid 1.855 times (exponential of 0.618) more eggs than those fed sugar. E. alacris and E. harpalyce laid fewer eggs than E. medon, and individuals with more scale loss laid fewer eggs.
