. The swarming usually began after 4:00 pm and lasted until 8:00 pm. Males in the vertical position slowly rose and fell over the vegetation. The swarming lasted 15–20 minutes; thereafter, the males rested on nearby leaves. After some time, the males took off again. We found a small extension stream nearby and found dead females floating after laying their eggs (Fig. 35). In July, the water in the stream disappeared, and the bottom was overgrown with grass.
