No evidence for behavioral responses to circularly polarized light in four scarab beetle species with circularly polarizing exocuticle

► The left-circular polarization of scarab cuticles was discovered in 1911. ► It is believed that this circular polarization may have a visual function. ► We report here on our multiple-choice experiments with scarab beetles. ► We found no evidence for behavioral response to circular polarization in 4 scarab species. ► By this we opened a new front of future research in this topic.
