Spectral cues for the regulation of bioluminescent flashing activity in the males of Twilight-active firefly Photinus scintillans (Coleoptera: Lampyridae) in nature
1994
Lall, A.B.
Males of the twilight-active firefly Photinus scintillans initiate bioluminescent flashing when a threshold intensity of ambient light is reached, irrespective of the type of habitat and the spectral cues available. Under dense shrubbery (closed space) the flashing period on average is about one-and-half times or more longer than in the meadows (open space). Long wavelength spectral cues dominate in closed space while both short and long wavelength cues are present in open space. Twilight-active fireflies use long wavelength spectral cues alone or short and long wavelength spectral cues together for the regulation of flashing in nature.
