Lamp-Lit Bridges as Dual Light-Traps for the Night-Swarming Mayfly, Ephoron virgo: Interaction of Polarized and Unpolarized Light Pollution

Fig 1

Nocturnal artificial sources of unpolarized and horizontally polarized light interact to attract polarotactic insects.

Unpolarlized light sources (e.g., street-lamps) may attract perching or flying nocturnal polarotactic insects directly (Ephoron virgo mayfly illustrated). Alternatively, unpolarized light from the street-lamp can become horizontally polarized through reflection from smooth, dark surfaces like asphalt, simulating the appearance of a water body.
