Text by Tony Irwin: "Gymnocheta is one of those greenbottles that changes as it gets older, becoming bronze- or copper-coloured. The green coloration is produced by the differential refraction of light from the many-layered cuticle. As the fly ages, particlularly if it spends much time in the sun, the cuticle changes in structure and the wavelength of light that is refracted changes."
