The UFO doesn’t imitate just one bug, but instead, many. It could pass as a beetle, ant, grasshopper, or who knows what. Either way, trout see it as a large bug that they can eat. These are one of the best flies to have for smaller creek fishing where trees and foliage are in abundance. As an attractor pattern, it works in about every corner of the country. Which is why this is a good fly to have for exploring new waters. A mixed dozen of these fishing flies will help to build a great terrestrial box for this summer.
