Halloween Pennant
Celithemis eponina · also called Halloween pennants
At the very tip of a tall reed swaying over a sunny marsh, a Halloween pennant clings loosely in place, its bold orange-and-black banded wings flagging back and forth in the breeze like a small pennant flying from its own tiny flagpole.
Overview
The Halloween pennant, Celithemis eponina, is a boldly banded dragonfly native to open, vegetated wetland habitat across a broad range of eastern and central North America. Its distinctive orange-and-black wings and habit of perching visibly atop swaying vegetation make it one of the more easily spotted and photogenic dragonflies near open marshes and ponds.
A dragonfly built to be seen swaying
Rather than hiding among dense vegetation, the Halloween pennant deliberately claims the most exposed, highest perch available, turning its bold colouration and constant swaying into an almost decorative fixture atop the wetland grass it calls home.
Status
Least Concern — widespread and common across suitable open, vegetated wetland habitat throughout eastern and central North America.
Halloween Pennant: common questions
Why is it called the Halloween pennant?
A Halloween pennant displays wings marked with bold orange and dark brown to black bands, a colour combination reminiscent of the traditional Halloween palette, and its habit of perching loosely at the tip of tall vegetation and swaying in the breeze resembles a small flag or pennant, together giving the species its common name.
Why does the Halloween pennant perch at the very top of grass and reeds?
The Halloween pennant characteristically perches at the very tip of tall grass, reeds, or twigs, a habit that gives it a clear, elevated vantage point for spotting prey and rivals while also making the species easy to spot swaying visibly in the wind.
Is the Halloween pennant a strong flier?
Not especially — a Halloween pennant flies with a relatively weak, fluttering style compared with some of the more powerful, direct-flying dragonfly species, a flight style well matched to its perch-and-wait hunting approach rather than sustained high-speed pursuit.
Where does the Halloween pennant live?
The Halloween pennant is native to open, vegetated wetland habitat across a broad range of eastern and central North America, generally favouring sunny ponds, lakes, and marshes with abundant emergent vegetation.
