Damselflies are flying insects of the suborder Zygoptera in the order Odonata. They are similar to dragonflies, which constitute the other odonatan suborder, Anisoptera, but are smaller and have slimmer bodies.
Damselflies generally eat smaller insects but also feast on insects as large or larger than they are. They have impressive, sharply pointed mandibles that chomp down on the smaller insects they catch.
