F statistics and p-values from analysis of covariance probing for differences in Cu1 eyespot size, eyespot center size, and center brightness between season form (DS and WS forms) and wing (FW and HW).

Wing size was used as a covariate. All data were log10 transformed. Brightness of eyespot centers was calculated as the integral of reflectances from 300-750nm, whereas visible brightness was integrated from 400–750 nm. Notice the significant interaction between wing and seasonal form in all analyses, indicating that forewings and hindwings do not respond to rearing temperature in similar ways.
