Migratory Dragonfly Short Course 

Point Pelee National Park, Ontario

September 8, 2012

9:30 am - 4:00 pm

Dragonfly migration is one of the most fascinating events in the insect world, but also one of the least-known. To shed light on this understudied phenomenon, the Migratory Dragonfly Partnership (MDP) is hosting dragonfly migration short courses across North America. The objective of these one-day events is to train participants to identify key migratory species and contribute data to ongoing MDP citizen science projects. 

Dragonfly migration occurs on every continent except Antarctica. The aptly-named wandering glider (Pantala flavescens), though less famed as a migrant than the monarch butterfly, makes annual flights across the Indian Ocean that are twice the distance of monarch migrations. In North America, migrations are seen annually in late summer and early fall, when thousands to millions of insects stream southward along coasts, lake shores, and mountain ridges from Canada down to Mexico and the West Indies, passing along both coasts of the United States and through the Midwest. Movement back north is less obvious, but we know it occurs because mature adult dragonflies appear early in spring at places where overwintering resident immatures (nymphs) have not yet emerged.

Only about 16 of our 326 dragonfly species in North America are regular migrants, with some making annual seasonal flights while others are more sporadic. The major migratory species in North America are common green darner (Anax junius), wandering glider (Pantala flavescens), spot-winged glider (Pantala hymenaea), black saddlebags (Tramea lacerata), and variegated meadowhawk (Sympetrum corruptum).

Although it spans three countries and has been documented since the 1880s, North American dragonfly migration is still poorly understood, and much remains to be learned about migratory cues, flight pathways, and the southern limits of overwintering grounds. The MDP is filling this gap by combining research, citizen science, and education and outreach to better understand North America’s migrating dragonflies, and to promote conservation of their wetland habitat.

Migratory Dragonfly Short Courses will educate participants about dragonfly life history, ecology, and migratory behavior, and provide training in MDP project protocols. The courses will include both a morning classroom and afternoon field component, and participants will receive a resource packet with migratory dragonfly publications, fact sheets, protocols, and identification guides.

LEAD INSTRUCTOR

Colin Jones

Colin is a lifelong naturalist who for many years worked as a Naturalist in Algonquin Provincial Park. Since 1999, he has worked for the Natural Heritage Information Centre, Ontario Ministry of Natural Resources in Peterborough where he deals primarily with rare species. Like many naturalists, Colin first developed a keen interest in birds and birding but this interest gradually grew into other areas. Over the past 20 years, he has been very interested in the study of Odonata (dragonflies and damselflies). He is a coordinator of the Ontario Odonata Atlas project, the co-editor of “Ontario Odonata” and the co-author of “A Field Guide to the Dragonflies and Damselflies of Algonquin Provincial Park and Surrounding Area.” Colin is also the Vice-President for Canada of the Dragonfly Society of the Americas and is on the steering committee for the Migratory Dragonfly Partnership.

ABOUT THE MIGRATORY DRAGONFLY PARTNERSHIP

The MDP is composed of dragonfly experts, nongovernmental programs, academic institutions, and federal agencies from the U.S., Mexico, and Canada. Together, we are combining research, citizen science, and education and outreach to better understand North America's migratory dragonflies and promote conservation of their wetland habitat.
