that one can observe significant deviations of catch at the same illuminations being originated from moonlight and other natural illumination without Moon. During the time, when the Moon is staying above horizon, the moonlight elongates the period of active flight. The increase of the intensity of moonlight increases the catch at positive polarization but, decrease at negative polarization, respectively. It is attributed to new result, that the species investigated employs the Babinet polarizationless point on the sky for its spatial orientation. It is published by the authors here some equations for expectation of the catch by light-trap at various illuminations to be calculated.
