Banded Pennant

Celithemis fasciata

With its strikingly 'ink-splattered' wings and a habit of waving from the tops of tall grasses, the Banded Pennant is the quintessential summer dragonfly. A master of the sit-and-wait hunt, it adds a touch of dramatic pattern to any backyard pond.

Behavior

The Banded Pennant is a classic 'percher' dragonfly, named for its habit of clinging to the tips of tall grasses and reeds where it flutters in the wind like a tiny flag. Unlike many dragonflies that spend their day patrolling large territories on the wing, this species prefers to sit and wait. From its elevated vantage point, it scans the air for small flying insects or encroaching rivals, darting out in short, acrobatic bursts before returning to the exact same perch.

These dragonflies are highly sun-dependent and are most active during the hottest parts of the day. When temperatures soar, they exhibit a fascinating thermoregulation behavior called 'obelisking,' where they point their abdomen straight up toward the sun to reduce their surface area and stay cool. While they are generally solitary hunters, you may find several individuals spaced out along a productive shoreline, each guarding its own preferred twig or reed.

Camera Tips

To successfully capture a Banded Pennant on camera, you must think like a percher. These dragonflies don't respond to traditional baits; instead, they are attracted to 'perch potential.' Identify the tallest, most prominent stalks of vegetation at the edge of a pond or wetland. If your yard lacks a natural perch, you can easily create one by sticking a 3-foot bamboo stake or a slender, branched stick into the ground near water. This 'artificial' perch will often become the preferred landing spot for any Banded Pennants in the area.

Position your camera approximately 18 to 36 inches away from the top of the perch, depending on your lens's minimum focus distance. It is crucial to set the camera at the same height as the tip of the stake; looking down on the insect often loses the intricate detail of the wing bands against the background. Aim for a side-profile shot, as this highlights the 'pennant' posture and the unique spotting on the abdomen. Ensure the background is as distant as possible to create a soft, blurred effect that makes the dragonfly pop.

Lighting is your best friend when filming insects. Place your camera so the sun is behind you or at a slight angle to the side, illuminating the dragonfly's wings. Since Banded Pennants are most active in full sun, avoid shaded areas which can lead to grainy images or slow shutter speeds. If your camera has a 'burst' mode or high-frame-rate video setting, use it—these dragonflies take off and land with incredible speed, and you’ll want multiple frames to catch the moment their patterned wings fully unfurl.

Frequently Asked Questions

Banded Pennants are most active during the brightest, warmest hours of the day, typically between 10 AM and 4 PM. They rely on the sun's heat to power their flight muscles and are rarely seen moving on cool or very cloudy days.

The best way to attract Banded Pennants is to provide a small water feature, like a garden pond, surrounded by tall, native grasses or thin stakes. They need these 'perches' to hunt effectively and will choose yards that offer high vantage points near the water.

Banded Pennants are carnivorous predators that eat a wide variety of small flying insects. Their diet consists primarily of mosquitoes, midges, gnats, and small flies, which they catch mid-air using their legs like a basket.

Yes, they are quite common in suburban environments across the eastern United States, provided there is a permanent source of still or slow-moving water nearby, such as a retention pond or a backyard water garden.

While both are 'pennants,' you can tell them apart by color. The Banded Pennant has clear wings with stark black or very dark brown bands, while the Halloween Pennant has distinct orange-tinted wings with brown markings.
