Rare
Under 5% of wildlife watchers report a Cerulean Dancer sighting in Monterrey on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 365th most-seen of the 413 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January and September
In those months about 10% of wildlife watchers report a Cerulean Dancer in Monterrey on a given day, against under 5% in February–August and October–December, the lowest months. Those are among Monterrey's wettest months, with about 110 mm of rain a month against 20 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Cerulean Dancer sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 cities where we can rate Cerulean Dancer sightings, Monterrey ranks 4th at under 5%. The best odds are in San José (Costa Rica, about 20%), Guadalajara (México, about 10%) and San Salvador (El Salvador, about 10%).
Same genus: Argia

GBIF citizen-science records
It is estimated from how often the Cerulean Dancer is recorded against all the insects logged in Monterrey (5 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.
