The lower Thames and Sydenham Rivers in southwestern Ontario have well established populations of Hetaerina titia that represent the northern range limit of the species. Although first discovered in 1985, these populations are not necessarily recently established. Adults appear from mid-August to early September and are most often seen around trees and shrubs overhanging moving water.
