The aquatic insect order Odonata includes the dragonflies and damselflies – remarkable insects strongly tied to the wetlands and waterways in which they breed and develop. Their aquatic habitat requirements in northern Illinois are under threat from climate change and human development which alter the hydrology of the systems upon which they rely. This talk, while providing a brief overview of their complex life cycle, will focus primarily on the dragonfly’s immature aquatic stage, known as a nymph, in which they spend the majority of their lives. Dragonfly nymphs have evolved fascinating morphological characters to adapt to specific aquatic niches. We will consider the specific needs of several local species and offer suggestions for how citizen scientists and private landowners can become involved in the monitoring and conservation of these essential creatures.
