Ascia is a genus of butterflies in the family Pieridae. It is monotypic, being represented by the single species Ascia monuste, commonly known as the great southern white, In this species the sexes may differ with the female being either light or dark colored. It is found from the Atlantic and Gulf coasts of the United States, and south to Argentina. It is migratory along the south-eastern coast of the United States, with strays to Maryland, Kansas, and Colorado.
Larvae have distinct body segments within which there appears to be four to six subsegments. They are purplish-green with two longitudinal, greenish-yellow stripes on each side and the dorsal side. When full-grown, they are approximately one and a quarter inches long. The wingspan in adults is 63–86 mm (2.5–3.4 in). Adults are on wing all year round in southern Texas, peninsular Florida and along the Gulf Coast.
A. monuste is a migrating species that moves in one direction within its life span and does not return. It breeds in Florida but sometimes migrates along the coast up to 160 km (99 mi) to breed in more suitable areas. This species seeks out appropriate plant hosts for oviposition by detection of compounds... Wikipedia →

Possible
About 20% of wildlife watchers report a Great Southern White sighting in Salvador on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 15th most-seen of the 42 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Great Southern White in Salvador on a given day, against under 5% in May–June and November, the lowest months. That is one of Salvador's driest months, with about 45 mm of rain against 170 mm in May.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Great Southern White sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 38 cities where we can rate Great Southern White sightings, Salvador ranks 3rd at about 20%, level with the leaders once rounded. The best odds are in San José (Costa Rica, about 20%) and Goiânia (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Great Southern White is recorded against all the insects logged in Salvador (12 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.
