UV light is electromagnetic radiation with wavelength shorter than that of visible light. The frequencies are invisible to human eyes but visible to many insects.
Insects are capable of detecting UV and colors using photoreceptors. Bees, flies and ants are able to simultaneously receive information from the wavelength and e-vector (vector representing the electric field of an electromagnetic wave) of incoming light using its receptors.
