Identification

Distinguished from other Celithemis by the extensive orange and black wing patterning rather than spot-based markings. Celithemis elisa (Calico Pennant) has checkered wing spots without the broad orange bands. Celithemis fasciata (Banded Pennant) has dark wings with pale spots, lacking orange coloration. Perches with wings held forward and slightly downward, a posture unique among North American pennants.

Medium-sized with a slender . Wings are long and narrow, marked with bold orange and black bands. The forewings display a black base and orange tips; hindwings show more extensive orange patterning. Body is dark with pale markings. are large and brown. Total body length approximately 38-42 mm, wingspan 60-70 mm.

Habitat

Open, sunny wetlands including marshes, ponds, lakeshores, and slow-moving streams. Prefers areas with emergent vegetation for perching. Often found in disturbed or human-modified wetlands. Tolerates brackish water conditions in coastal areas.

Distribution

Eastern North America from Ontario and Quebec, Canada south to Florida, and west to Colorado and Texas. Disjunct reported in the Caribbean and Middle America. Absent from most of the Great Plains and western North America.

Seasonality

Active from late May through September in northern portions of range; year-round in Florida and the Deep South. Peak abundance in July and August in most regions.

Diet

Aerial capturing small flying insects including mosquitoes, , and small flies. Has been observed hunting from elevated perches.

Life Cycle

laid in water or on aquatic vegetation. Aquatic nymph stage lasts approximately one year. occurs in late spring. live 2-4 weeks.

Behavior

Frequently perches on tall emergent vegetation, often at the very tip of stems. Holds wings angled forward and slightly downward when perched, unlike most that hold wings horizontally or vertically. Males defend territories from elevated perches. Strong, direct with relatively slow wingbeats compared to smaller .

Ecological Role

of small flying insects in wetland . Nymphs serve as prey for fish and other aquatic predators. provide food for birds and other .

Human Relevance

Popular subject for photography and observation due to distinctive coloration and accessible perching . Sometimes used as for wetland health assessment. No significant pest or beneficial economic status.

Thermoregulation

The orange wing coloration has been suggested to aid in by absorbing solar radiation, though this hypothesis remains untested.
