The Dragonfly Swarm Project allows everyone to participate in a large-scale study of dragonfly swarming behavior. Participants observe dragonfly swarms wherever they occur, make observations of the composition and behavior of the swarm, then submit a report online. Data is compiled from the reports for two purposes: 1) to publish data from a massive number of dragonfly swarms in the scientific literature, making this information available to scientists, and 2) to provide information about this behavior to the public. By collecting information from eye-witnesses, we can improve our understanding of this fascinating behavior together! Because any given person has to be in the right place at the right time to see a dragonfly swarm, this project isn't possible for a single scientist to do alone. Collecting data from a large network of people is thus the best way to study dragonfly swarming behavior. Participation requires only curiosity and a few minutes of your time, so keep an eye out for dragonfly swarms in your area this summer and send in your reports!
