Darners
Family Aeshnidae
Genus Basiaeschna
Springtime Darner (Basiaeschna janata)



Flight season: mid-May to late June.

Population: not uncommon and apt to be encountered along the trans-Canada Trail, usually near streams but sometimes at marshes. This darner forages low along the trail or in the vegetation bordering it, often seen with Stream Cruisers.

Length: about 60 mm to 65 mm. The lateral thoracic stripes with black edging, dark patches at the bases of the wings and early flight season distinguish this species from other darners.
