Although predators themselves dragonflies have many things that they need to be wary of. At Dodge Nature Center the dragons have to keep an eye on the sky, where birds and other dragons are a potential threat, and the other on the water, where larger fish, frogs and turtles, like the one below, are a danger.
When they are young painted turtles are mostly carnivorous, eating mainly beetles, maggots, and larvae, including dragonfly larvae. As they get older they become more omnivorous, at this point they mainly eat fish, insects, fruit, plants, and carrion. I took this pic because I loved the symmetry between the turtle and the log.
