Reflection Measurements Used In The Analysis Of Structural Colours Of Beetles

Reflectance measurements have been carried out on the elytral cuticle of two beetles. Great differences arise in the tiger beetle Cicindela campestris depending on the extremely structured surface and colour variation from point to point. In comparison the buprestid beetle Chrysochroa vittata appears more even. Indeed macroscopically it looks completely smooth, but there are microscopical structures complicating reflection measurements.
