Mestra is a genus of nymphalid butterfly. It contains the single species Mestra dorcas, the Jamaican mestra, which is found from southern North America to South America and possibly Mestra cana, the St Lucia mestra, found in the Lesser Antilles (though this may be a misidentification).
The wingspan is 35–50 mm. Adults are on wing year round in southern Texas, but it is most numerous from June to November. They have been recorded feeding on the nectar of Lantana flowers. Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Mestra sighting in Mexico City on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 369th 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.
November
In that month about 10% of wildlife watchers report a Common Mestra in Mexico City on a given day, against under 5% in December to October, the lowest months. That is one of Mexico City's driest months, with about 20 mm of rain against 150 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Mestra sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
7th of 7
Of the 7 cities where we can rate Common Mestra sightings, Mexico City ranks 7th at under 5%. The best odds are in San Pedro Sula (Honduras, about 10%), Monterrey (México, about 10%) and San Antonio (United States, about 10%).
Same family: Nymphalidae
The closest relatives of the Common Mestra that you can see in Mexico City (family Nymphalidae, Brush-footed Butterflies) are Juno Silverspot (about 20%), West Coast Lady (about 20%) and Monarch (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Mestra is recorded against all the insects logged in Mexico City (10 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.
