The Halloween pennant (Celithemis eponina) is a species of dragonfly in the family Libellulidae. It is native to eastern North America, as well as the West Indies. The Halloween pennant's wings are entirely orange-yellow in color with dark brown bands, the Halloween inspiration for its common name. Dragonflies of its genus perch at the tips of plants, waving in the breeze like pennants. The young has yellow markings, including a stripe on its back. The adult male and female may develop pale red markings, especially on the face. This species is about 38 to 42 millimetres (1.5 to 1.7 in) long.
This species occurs in eastern North America. In the southern part of its range of The Bahamas and Cuba, it is in season all year round. In northern latitudes it can be seen from mid-June to mid-August. It ranges as far north as southern Canada and as far west as the United States east of the Rocky Mountains, in New Mexico and Colorado. It lives in wet habitat types such as ponds, marshes and lakes, where it perches sometimes on vegetation.
The female lays eggs in the morning on open water with the male still attached at the head. This... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Halloween Pennant is recorded against all the insects logged in Montreal (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
