How do insects see flowers?

Flowers, such as this Narcissus Pseudonarcissus flower (i.e., a daffodil), look startlingly different in UV (Ultraviolet) light.   Note: UV has a wavelength of 1-400 nm, compared to 400-700 nm for Visible light, where nm stands for nanometer = 10^-9 m, or 1 billionth of a meter. nanos is the Greek word for "dwarf".
