Went to "the Pond" a few days ago with my daughter and Diablo for the evening rise of Buzzers.
I ended up catching three small Asp between 30 and 40 cm. As usual missed or lost twice as many some bigger.
At dusk the bats began diving at my fly more than the naturals so it was time to quit. In the video there is one of the bats taking a dive right at us. If you listen close you can hear an owl hooting in the background.
