This book deals with the light- and pheromone trap catch of moth (Lepidoptera), beetle (Coleoptera), bug (Heteroptera) and caddisfly (Trichoptera) species in connection with gravitational potential of the Sun and the Moon and the night sky polarization originated by these celestial bodies. Light-trap catching data of Agrotis exclamationis L. were used of a fractionating light-trap. This trap operated for three years from spring to autumn, every night for ten hours. The moth, bug and caddisfly species were taken from the light-trap data of the Hungarian Light-trap Network from years between 1959-2011. Our own light traps collected the caddisfly species. We worked up the pheromone traps data of eight moth species from years between 1982-2013. We have found that the collection results of all the examined species are greatly influenced by the gravitational potential of both the Sun and the Moon and the night sky polarization originated these celestial bodies.
