Divergent Responses of Insectivorous Bats and Flying Insects to Experimental LED Illumination of Different Spectra

We conducted a field experiment to investigate the effects of short-term nighttime illumination on nocturnal flying insects and insectivorous bats in previously unlit remnant bushland. We compared these organisms’ responses to three types of light-emitting diode (LED) lights, each with a unique spectral composition (cool white (CW) - λP 457 nm, filtered white (FW) - λP 586 nm, and amber (A) - λP 601 nm), as well as a control (C) group without illumination.
