The blue-eyed darner (Rhionaeschna multicolor, syn. Aeshna multicolor) is a common dragonfly of the family Aeshnidae; native to the western United States, it is commonly sighted in the sagebrush steppe of the Snake River Plain, occurring east to the Midwest from central Canada and the Dakotas south to west Texas and Oklahoma. In Central America it occurs south to Panama. This is usually the second earliest darner to emerge in the spring, with the California darner emerging first. It hunts small flying insects while on the wing. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blue-Eyed Darner is recorded against all the insects logged in Toluca (14 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.
