The adaptation of butterfly wing cooling
Description
Data 1. The measured emissivity spectra of wings of 40 butterfly species used in testing the correlation between wing cooling capacity and range temperature of butterflies. Data 2. The temperature measurements and corrections of wings of 40 butterfly species used in testing the correlation between wing cooling capacity and range temperature of butterflies. Data 3. The ultrastructural characteristics of wing ultrastructure of the three Danainae species. The parameters were measured from regions with the minimum, median and maximum emissivity across the wings.

Wing temperature measurements The wing temperature data were extracted from the photos taken with a thermal camera (CEM DT-9885) using IRMeter v1.0.4. Then corrected following Tsai et al. 2020 (DOI: 10.1038/s41467-020-14408-8). Emissivity measurements Emissivity data were calculated from the measured optical spectra, as it equals 1 – transmissivity – reflectivity in mid-infrared waveband, as Kirchhoff's law demonstrated. The transmissivity and reflectivity spectra were collected using a Fourier infrared spectrometer (Thermo Nicolet iS50) at a stable room temperature of 25°C. Wing scale structure measurements Wing scale structure was examined using a scanning electron microscope (SEM) (Zeiss EVO-LS10) and a transmission electron microscope (TEM) (JEOL JEM-1400 Flash). All data were measured from images using Fiji (ImageJ).
