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 →

With luck
About 10% of wildlife watchers report a Blue-Ringed Dancer sighting in Phoenix on a given day, based on 24 verified sightings from GBIF citizen-science data. It is the 100th most-seen of the 264 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
April–June and October–November
In those months about 10% of wildlife watchers report a Blue-Ringed Dancer in Phoenix on a given day, against under 5% in July–September and December–March, the lowest months. Those are among Phoenix's driest months, with about 10 mm of rain a month against 35 mm in January.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Blue-Ringed Dancer sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 10 cities where we can rate Blue-Ringed Dancer sightings, Phoenix ranks 8th at about 10%, level with the leaders once rounded. The best odds are in Dallas (United States, about 10%), Austin (United States, about 10%) and Mesa (United States, about 10%).
GBIF citizen-science records
It is estimated from how often the Blue-Ringed Dancer is recorded against all the insects logged in Phoenix (24 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.
