Yes,other larger dragon flies.

www.eduweb.org gave me the following info- -

<font size="3" face="Arial">Dragonflies do have enemies. Among the species that catch and eat adult dragonflies and damselflies are birds (e.g. Wagtails and Hobbies), Spiders (many damselflies are caught in webs), Frogs, and larger species of dragonflies (which catch and eat other dragonflies and damselflies). </font>

<font size="3" face="Arial">In the larval stage, which is spent underwater, they are preyed on by fish, frogs, toads and newts, and other water invertebrates. Their defenses include their excellent eyesight and flying skills which can help them to evade capture. Some are colored black and yellow, or black and red, which is the universal warning coloration and may deter some of the bird predators.</font>
