Dragonflies are carnivorous—they feed on other live insects. Most of their diet consists of gnats, mosquitoes, and other small insects, but they also prey upon bees, butterflies, damselflies, and even on other dragonflies.
When I first spotted this male Eastern Pondhawk dragonfly (Erythemis simplicicollis) on Saturday at Jackson Miles Abbott Wetland Refuge, it had just perched on a stalk of vegetation. As I moved a little closer, the dragonfly changed its position, looking almost like it was trying to hide behind the stalk. What I did not realize at the time was that the dragonfly had just snagged a damselfly and was preparing to eat his lunch. Obviously he did not want to share it with me.
Almost all of the times that I have seen dragonflies with prey, they been Eastern Pondhawks, which seem to be particularly fierce predators. Some dragonflies eat their prey in mid-air and I never see them do so. It may also be the case that some other dragonflies fly up into the trees and consume their prey out of sight, while the Eastern Pondhawk is content to eat in public.
It is often difficult to judge the relative size of dragonflies and damselflies. This images lets you see how much smaller and thinner damselflies are than dragonflies. An Eastern Pondhawk is about 1.7 inches (43 mm) in length and the unidentified damselfly looks to a bit over an inch (25 mm) in length.
