The long-tailed skipper (Urbanus proteus) is a spread-winged skipper butterfly found throughout tropical and subtropical South America, south to Argentina and north into the eastern United States and southern Ontario. It cannot live in areas with prolonged frost. It is a showy butterfly, with wings of light brown tinted with iridescent blue, and two long tails extending from the hindwings. The robust body is light blue dorsally. It has a large head, prominent eyes, and a wingspan between 4.5 and 6 centimeters.
It lays white or yellow eggs, singly or in small clusters, which hatch into a caterpillar with a yellowish body and large, dark head. After two to three weeks, the caterpillar forms a pupa. Its pupa is contained in a rolled leaf and covered in fine bluish hairs. The pupa stage may last from one to three weeks, after which the adult emerges.
The caterpillar of this skipper is a common pest of crops, especially beans, in the southern United States. For this reason, it is sometimes called the bean leafroller in that area. The caterpillars feed on leaves of plants in the legume family such as wisteria and butterfly peas and then roll the leaves around themselves... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Long-Tailed Skipper is recorded against all the insects logged in Mexico City (65 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.
