Additions to Williams’ Dilemma: Can Moonlight Impede Insect Activity? (Effectiveness of the Catch in the Vicinity of Moonrise and Moonset)

Abstract

The study deals with the effectiveness of light-trap catch of insects in relation to moonrise and moonset. It was found that the catching results are better during the hour of moonrise or the hour after it, than in the hour before moonrise for all five species. However, the catch decreases during the hour of moonset or the hour following it. The results confirm that the moonlight did not decrease, but rather increased the effectiveness of the light-trap catch.
