Migratory dragonflies are leaving Missouri and Illinois for areas further south. It’s part of these great travelers' annual migration pattern.
The Wandering Glider and Spot-winged dragonfly typically pass through the region in July. By early August, they are on their way out.
Bob Gillespie is a natural history biologist at the Missouri Department of Conservation. He says, up until a few year ago, scientists knew very little about how they migrate.
