Brachymesia furcata, commonly known as the red-tailed pennant, is part of the dragonfly order Odonata. It is a species of skimmer belonging to Libellulidae, one of the largest dragonfly families in the world.

Current populations of B. furcata are stable. The IUCN conservation status of B. furcata designates the species as "least concern" as last reviewed in 2017.
Similar to other dragonflies, B. furcata has a life cycle consisting of three primary stages: egg, nymph, and adult. Its eggs are laid in still-water conditions on submerged aquatic plants or directly into the water depending on the environmental conditions. Marshes, ponds, lakes, and other mildly saline aquatic habitats are all potential locations for dragonflies to colonize. Bottom debris and aquatic vegetation provide both sustenance as well as hiding spots for the newly hatched dragonfly nymphs. After undergoing a few molts, the nymph transitions... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Red-Tailed Pennant is recorded against all the insects logged in Santo Domingo (10 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.
