This cheerful-looking paddle-tailed darner (Aeshna palmata) patrolled a large section of a lake at Beacon Hill Park in Victoria, BC. Occasionally, the large dragonfly would pause on its broad sweeps and survey a small area, especially near trees, probably seeking insects that may be in the vicinity.
