Lake Darner
Aeshna eremitaLake darners rank among the largest dragonflies in North America, patrolling shorelines with swift, tireless flight as they hunt aerial insects. Males vigorously defend territories along cold boreal lakes and marshy bays, frequently perching on sunlit tree trunks or emergent vegetation. Females insert eggs into living aquatic plant stems just beneath the water line using a sharp, blade-like ovipositor.
