The Last Best Bug Lab in the Intermountain West

River Continuum Concepts

A recently emerged dragonfly left the larval skin behind to rule the skies as a proper dragonfly. The small wing-like looking lobes on the right are called wing pads--they contain the wings while the nymph grows underwater for about 1 year. The nymph's tracheae are also visible as the white thread-like structures on the left side. Yes, as with all other paurometabolous/ hemimetabolous insects, the tracheae had to be shed for the nymph to transform into an adult. Aren't you glad you didn't need to do that?

Some dragonfly larvae (aka nymphs) are just naturally happy.
