When you are standing at a slow-moving stream, Water Boatmen are the majority of insects you will see as they are the largest group and most common group of water bugs. Although being aquatic, they show up at our black lights regularly. There are 500 species in North America.
They can be found in a variety of habitats and some are highly tolerant of pollution. They feeding preferences are equally as high in variety. This is because of their modified beaks that allow them to grind up food and not just juices. They also serve as food for many fish.
