Andrea B. Posted June 11, 2013 Share Posted June 11, 2013 Blum, A.G. (2013) Nemophila maculata Bentham ex Lindley (Boraginaceae) Fivespot. Flowers photographed in visible and ultraviolet light. http://www.ultraviol...ulata-fivespot/ Boyce Thompson Arboretum, Superior, Arizona, USA25 April 2013Wildflower in botanical garden Pollinator: Solitary bees. Comment:In ultraviolet light the Fivespot undergoes a wonderful reversal where the Visible dark spots become UV-bright while the Visible white portion of the petals flips to UV-dark. Additionally in UV, there is a great deal of iridescence on the petals which may produce a flashing signal when the breezes flutter the petals.N. maculata is a California native. Reference:1.
