Argia sedula, the blue-ringed dancer, is a species of narrow-winged damselfly in the family Coenagrionidae. It is found in Central America and North America. The IUCN conservation status of Argia sedula is "LC", least concern, with no immediate threat to the survival of the species. The population is stable.
It appears that Argia sedula is particularly affected by global warming, which is causing the size of individuals to vary depending on location and climate fluctuations. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Blue-Ringed Dancer is recorded against all the insects logged in San Diego (13 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.
