Abstract: Polarized light is different from common light, and it vibrates in one direction on light vectors and includes linear polarized light, circularly polarized light, elliptically polarized light, etc. It was verified that polarized light could affect behavior of many insects, such as flight navigation of Apis mellifera, mating of Heliconius cydno chioneus, selection of oviposition places by Papilio aegeus, etc. The reflection of circularly polarized light by scarab beetles could be used as a taxonomic character. Ommatidia accumulated in the dorsal rim area (DRA) of the compound eye are the main organs sensing polarized light. Electrophysiological studies recently showed that the anterior optic tubercle (AOTu) is a part of the polarization vision pathway of locusts. The polarized light traps have been developed for ground beetles in Hungary.

Key words: Liner polarized light, circularly polarized light, insects, polarization vision, photoreceptor
