Background information and definitions
Artificial lighting disrupts the activity of nocturnal moths, and some species of moth have been shown to respond to polarized light more than to non-polarized light of the same intensity (Danthanarayana & Dashper 1986), because their eyes are particularly sensitive to polarized light (Belušič et al. 2017). Therefore, restricting the use of polarized light may reduce the impact of artificial lighting on moth populations.
