Argia vivida vary in color, although they are typically associated with the bright blue coloration. Other variations include red, brown, or grey depending on the type of morph and temperature.

GBIF citizen-science records
It is estimated from how often the Vivid Dancer is recorded against all the insects logged in San Diego (543 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.
