They also provide a good protein source for any fish that choose to eat them, and help control algae populations. The adults don’t live in the water itself, but are always found near freshwater, typically slow-moving sources such as ponds near where they were initially born and will often land on the water’s surface to get a drink or hunt for small prey.
