Dragonflies Predators and Prey

Dragonflies, like this Blue Dasher, are one of the insect world's most effective predators.  There were many when I took these pictures this morning in Springbrook's south prairie.

But dragonflies also get eaten, mostly by birds, who pluck thier wings off and then eat the nutritious bodies.  Cast off wings can be found beneath bird's perches, like this plucked wing I found this morning on this blade of grass.
