Pyrisitia nise, the mimosa yellow, is a butterfly in the family Pieridae. It is found from Argentina north to the Texas Gulf Coast and throughout central and southern Florida, northward to the Tennessee Valley. It is an occasional stray to central Texas and south-eastern Arizona and rarely to southern California, southern Colorado and Kansas. The habitat consists of brushy woodland edges.
The wingspan is 29–51 mm (1.1–2.0 in). Both sexes are yellow. The upperside of the forewing has narrow black outer edges. Black margins of the hindwing are uncommon in males, but always absent in females. Adults are on wing from May to August in southern Florida, September to November in southern Texas and all year round in the tropics. Adults feed on flower nectar.

Rare
Under 5% of wildlife watchers report a Mimosa Yellow sighting in Mexico City on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 442nd most-seen of the 557 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Mimosa Yellow in Mexico City on a given day, so our monthly data shows no clear season.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Mimosa Yellow sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Mimosa Yellow sightings, Mexico City ranks 3rd at under 5%. The best odds are in Monterrey (México, about 10%) and Rio de Janeiro (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Mimosa Yellow is recorded against all the insects logged in Mexico City (8 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.
