Behavior
These dragonflies are agile fliers but spend much of their time perched, surveying their surroundings for prey or intruders. They are less skittish than larger dragonfly species, often allowing humans to approach within a few feet. Their flight is characterized by short, darting bursts, usually returning to the exact same spot after a brief aerial sortie.

Camera Tips
To capture the Common Parasol on a backyard camera, the most effective strategy is 'perch placement.' These dragonflies are creatures of habit and will almost always choose the highest point in a sunny area near water. If your garden lacks natural perches, place a 1-meter (3-foot) bamboo stake or a thin dry branch near a pond or birdbath. Position your camera on a tripod roughly 60–90 cm (2–3 feet) away from the tip of this perch, ensuring the background is distant to create a beautiful 'bokeh' effect that makes the red wings pop.
Because dragonflies are cold-blooded, lighting is everything. For the most vibrant colors, angle your camera so the sun is behind you, illuminating the dragonfly's wings directly. The period between 10:00 AM and 1:00 PM is prime time, as this is when the males are most active in defending their territories and displaying their brilliant red coloration. If your camera has a 'Macro' mode, enable it to capture the intricate vein patterns in the wings.
Since insects don't always trigger standard PIR (heat-based) sensors, you should set your AI camera to 'Motion Detection' with high sensitivity. Alternatively, use a 'Time-Lapse' mode with a trigger interval of every 10–20 seconds during peak sunlight hours. This ensures you catch the dragonfly even if it remains perfectly still on its perch for long periods. If you are using a trail camera with a fixed focal length, you may need a close-up lens attachment to get a sharp image at such a short distance.
Finally, consider the wind. Dragonflies are sensitive to movement and may fly away if foliage is whipping around them. Clear any tall weeds from the immediate vicinity of your designated 'photo perch' so the AI can easily lock onto the dragonfly's silhouette without being distracted by moving leaves. This also helps ensure that the camera's focus stays locked on the insect rather than a stray blade of grass.
