Argia moesta
In 3 days ~10% in a week ~20%
The powdered dancer (Argia moesta) is a damselfly of the family Coenagrionidae. It is native to North America. It may be seen year-round in at least some of its range. The common name refers directly to the male's pruinosity, appearing to be covered with a powdery blue or grayish substance. Older males are more pruinose, and may even be more ash white than blue. The specific epithet moesta, means sorrowful, and may refer to customs (such as those on Ash Wednesday) of dusting oneself with ashes to express sorrow or mourning.
Males have a blue tip at the end of the abdomen. Immature (freshly moulted, or teneral) males are tan to dark brown, turning darker with age and becoming almost completely whitish (pruinose) at maturity. Females come in blue and brown forms based on the color of the thorax, which has hair thin dark shoulder stripes.
The blue form female is very similar to the female blue-fronted dancer; a key to separating these two is the number of cells below the stigma: our species has two cells below the stigma where a blue-fronted dancer has one.
During mating, a male uses claspers at the end of his abdomen to grab a female... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Powdered Dancer is recorded against all the insects logged in Saguaro National Park (8 verified sightings from 2019 to 2026), 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.
