Lake Darner
Aeshna eremitaLake darners patrol clear boreal lakes, peat bogs, and sluggish northern streams in search of airborne prey. Males fly tireless search loops along sunny shorelines, actively chasing off rival dragonflies and snatching mosquitoes mid-flight. Females use their sharp ovipositors to insert eggs directly into aquatic plant stems beneath the water surface.
