Wing phenotype data used in the paper "Temporal relationship between genetic and warning signal variation in the aposematic wood tiger moth (Parasemia plantaginis)" by Galarza et al. Shown are the reflectance values (hue) of Parasemia plantains male fore- and hindwings. The column headings indicate: fw col hue UV= Ultraviolet wavelength reflectance in the forewing fw col hue SW = Short wavelength reflectance in the forewing fw col hue MW = Middle wavelength reflectance in the forewing fw col hue LW = Long wavelength reflectance in the forewing fw blackratio = Forewing black ratio (in the manuscript referred to as signal size) hw col hue UV= Ultraviolet wavelength reflectance in the hindwing hw col hue SW = Short wavelength reflectance in the hindwing hw col hue MW = Middle wavelength reflectance in the hindwing hw col hue LW = Long wavelength reflectance in the hindwing hw blackratio = Hindwing black ratio (in the manuscript referred to as signal size)
