Fig. 5.

Reflectance spectra (from 250 to 900 nm) from the central area of the wing of Hermetia illucens recorded with a spectrophotometer. Illumination/detection is normal to the surface. (a) Reflectance spectra from the dorsal side of male and female wings (means ± SEM). (b) Reflectance spectra from the ventral side of male and female wings (means ± SEM). (c) Differences in the reflectance spectra of the dorsal side of male and female wings in the three distinct wavelength ranges corresponding to ultraviolet (250–399 nm), blue (400–500 nm), and green (501–565 nm). (d) Differences in the reflectance spectra of the ventral side of male and female wings in the three distinct wavelength ranges corresponding to ultraviolet (250–399 nm), blue (400–500 nm), and green (501–565 nm). Columns in (c) and (d) indicate means ± SEM. Ns denotes not significant difference, * indicates significant difference at p < 0.05, Student’s t test for independent samples.
