Halloween Pennant (Celithemis eponina)

The Halloween Pennant dragonfly looks as though someone painted its wings for autumn. Bands of orange, gold, and deep brown cover all four wings, giving this colorful insect an almost butterfly-like appearance.

Despite its festive name, you do not have to wait until October to find one. Halloween Pennants are warm-season dragonflies commonly seen around ponds, marshes, lakes, and grassy wetland edges. They often perch at the very tips of stems, swaying in the breeze like tiny flags.

Quick Facts

Halloween Pennants occur from portions of New Mexico and Colorado eastward to the Atlantic Coast. Their range extends north into southern Canada and south into the West Indies.

How to Identify a Halloween Pennant

The Halloween Pennant is best recognized by its golden-orange wings crossed with bold brown bands and spots. A complete dark band appears near the outer portion of each wing, extending from the leading edge to the trailing edge.

That complete band is especially helpful when separating this species from the similar Calico Pennant. On a Calico Pennant, the dark mark near the wing tip appears as a smaller spot rather than a band crossing the entire wing.

The body is slender, while the wings appear broad and heavily patterned. Depending on age and sex, the face, abdomen, wing veins, and other markings may appear yellow, orange, brown, or reddish.

At rest, a Halloween Pennant frequently chooses the tip of a grass stem, twig, shrub, or other exposed perch. The dragonfly may rock back and forth as the vegetation moves, resembling a small pennant fluttering on a pole.

Male vs. Female Halloween Pennant

Male and female Halloween Pennants share the same patterned orange-and-brown wings. Their body colors provide the clearest clues.

Mature males

Mature males develop deeper orange or reddish markings. Their faces, wing veins, and abdominal stripe may become noticeably redder as they age. The abdomen is primarily dark, with orange or reddish coloring near the thorax.

Females

Females generally retain more yellow and brown coloring. A yellow stripe runs along the upper surface of the abdomen, while the sides may also appear yellow.

Immature males

Young males can resemble females because their markings begin yellow. As they mature, those areas gradually become orange or reddish.

Therefore, body color alone may not always identify the sex of a young dragonfly. The changes become more apparent as males reach maturity.

Habitat and Range

Halloween Pennants are closely associated with freshwater habitats. They occur around ponds, lakes, marshes, reservoirs, borrow pits, wet prairies, and other areas with still or gently moving water.

Aquatic vegetation is particularly valuable. Underwater plants provide shelter and hunting areas for developing nymphs, while reeds, grasses, and shrubs offer perches for adults.

Although breeding occurs near water, adults may travel into open fields and grasslands to hunt. They often return to wetland edges when searching for mates or places to lay eggs.

Behavior

The Halloween Pennant is a surprisingly sturdy flyer. While many dragonflies retreat during cool, windy, or damp weather, this species may remain active during strong breezes and even light rain.

Its broad wings allow it to ride moving air while perched or flying. On windy days, several individuals may gather along pond edges, each balancing on the tip of a stem.

Male Halloween Pennants are also less territorial than many other dragonflies. Instead of aggressively defending individual sections of shoreline, several males may perch relatively close together while watching for females.

Diet and Hunting

Adult Halloween Pennants are aerial predators. They capture mosquitoes, flies, midges, and other small insects while flying above water or nearby vegetation.

Large compound eyes help them detect movement in several directions. Their legs curve forward during flight, forming a basket that traps prey.

Once an insect is caught, the dragonfly may eat it in the air or return to a perch. By feeding on numerous flying insects, Halloween Pennants form an important part of the wetland food web.

Their aquatic nymphs are also predators. They hunt small aquatic arthropods while hiding among submerged plants.

Life Cycle and Reproduction

Like other dragonflies, the Halloween Pennant spends the first part of its life underwater.

After mating, the male and female may remain connected in tandem. The female lowers the tip of her abdomen to the water and releases her eggs while the pair flies above the surface.

The eggs hatch into aquatic nymphs. These young dragonflies live among submerged vegetation, where they hunt smaller aquatic animals and molt repeatedly as they grow.

When development is complete, the nymph climbs from the water onto a stem, branch, or other support. Its outer skin splits, and the winged adult slowly emerges.

The newly emerged dragonfly must allow its wings and body to expand and harden before taking its first flight.

Conservation Status

The Halloween Pennant has a NatureServe global conservation rank of G5, which means the species is considered secure across its overall range.

Nevertheless, healthy populations depend on freshwater wetlands and surrounding vegetation. Draining ponds, removing shoreline plants, pollution, and excessive pesticide use can reduce suitable habitat for dragonflies and their aquatic young.

Fun Facts About the Halloween Pennant

• Its orange and brown wings inspired the name “Halloween Pennant.”
• The word “pennant” refers to its habit of perching on stem tips like a flag.
• Halloween Pennants may remain active in wind, mist, and light rain.
• Mature males become redder as they age.
• Males are less territorial than many other dragonflies.
• Adults may hunt over fields far from the water.
• Their butterfly-like wings make them easy to notice from a distance.
• They often return to the same exposed perch after a short flight.

Similar Species

• Calico Pennant: The closest look-alike. Its wings are clearer, with smaller dark spots rather than a complete band crossing each wing. The abdomen also has distinctive heart-shaped spots.
• Banded Pennant: This smaller pennant has strong black wing markings, but its wings lack the Halloween Pennant’s overall golden-orange wash and repeating Halloween-colored pattern.
• Widow Skimmer: The Widow Skimmer has large dark patches near the bases of its wings. Mature males also develop bold white wing bands, while Halloween Pennants have orange wings patterned with several dark bands and spots.
• Painted Skimmer: This orange dragonfly may appear similar in flight. However, its wings have broad amber coloring and dark patches rather than the Halloween Pennant’s repeating bands across all four wings.

The easiest identification clue is the complete dark band near the outer portion of each orange-tinted wing.

Frequently Asked Questions

Are Halloween Pennant dragonflies dangerous?

No. They do not sting and are not dangerous to people. A dragonfly may bite when handled roughly, but it would much rather escape.

Why is it called a Halloween Pennant?

Its orange-and-brown wing pattern resembles traditional Halloween colors. The name “pennant” comes from its habit of swaying on exposed stems like a small flag.

Where can I find a Halloween Pennant?

Look around sunny ponds, marshes, lakes, wet fields, and grassy wetland edges. Scan the highest tips of reeds, grasses, and bare twigs.

Do Halloween Pennants eat mosquitoes?

Yes. Adults capture mosquitoes and other small flying insects, while aquatic nymphs consume insect larvae and other small aquatic prey.

Are males and females different colors?

Yes, although the difference may be subtle. Females and young males have more yellow markings. Mature males gradually become orange or reddish.

Are Halloween Pennants rare?

They are considered secure and can be locally common within suitable habitat. Their visibility depends on location, season, weather, and the availability of healthy wetlands.

A Naturalist’s Note

The Halloween Pennant is the sort of dragonfly that demands a second look. Its broad patterned wings may first suggest a small butterfly fluttering among the grasses.

Then it lands.

Balanced on the narrow tip of a stem, it rocks with every breeze while somehow remaining perfectly in place. The orange wings glow in the sunlight, and their dark bands turn an ordinary pond edge into something unexpectedly dramatic.

Fortunately for photographers, Halloween Pennants often return to familiar perches. Waiting beside that chosen stem may be far more successful than chasing the dragonfly through the grass. Sometimes nature photography is less about moving quickly and more about recognizing where your subject plans to come back.
