Iridescence:
Fauchea laciniata is recognized by its beautiful iridescence which varies among individuals and can be blue-violet or yellow-green in color. This iridescent sheen is caused by gland cells located within the surface layer of the epidermis (Lamb et al. 2005). Light is reflected and refracted off of this multi layered cuticle to form a variety of brilliant colors (Mondragon et al. 2003). This phenomenon is called “thin layer interference” (Vidargas, 2003).
