Under sunlight, approximately 70 mating
pairs were recorded daily (Figure 1). Mating
began at 08:30 and peaked at 10:00 with an
average of 23 mating pairs at a light intensity
of approximately 110 μmol m-2s-1. Eightyfive
percent of the mating activity occurred
during the morning. Mating activity decreased
when the light intensity was more than 110
μmol m-2s-1. On average, two mating pairs
were observed at 13:00 when light intensity
