The present study discusses the light trapping of insects depending on the environmental illu- mination, twilight polarization phenomena and the moon phases. The trapping data were taken of Hun- garian national light-trap network. The important results are the followings: The Babinet-point, a polariza- tion free spot of the sky at twilight, can be a role of orientation of insects. The height of the Moon above the horizon is in negative correlation with the number of the caught insects. The maximum individual number of species was collected at various moon phases.
