Wing-lift-induced changes in eyespot size. N (no change) or R (reduction) is indicated at the bottom right in each panel. Red arrows indicate modified parafocal elements (PFEs). Right (experimental) and left (control) posterior eyespots are enlarged below a whole butterfly image. a No treatment. The right and left posterior eyespots are compared in size throughout this study. b, c Transient lift treatment. d-f No contact treatment. g, h Semiparabiosis
