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 →

GBIF citizen-science records
It is estimated from how often the Common Mestra is recorded against all the insects logged in San Luis Potosí (6 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.
