Anthanassa texana, the Texan crescentspot, is a species of butterfly in the family Nymphalidae. It is found from Guatemala north through Mexico to southern California, east across the southern United States to northern Florida, Georgia and South Carolina. Strays may be found up to Arkansas, Missouri, Illinois, South Dakota, and central Nevada. The habitat consists of deserts, dry gulches, open areas, streamsides, road edges, and city parks.
The wingspan is 32–48 mm. Adults are on wing from March to November in southern Florida and Arizona. They are on wing year round in southern Texas and the tropics. There are several generations per year. Adults feed on flower nectar.
The larvae feed on the leaves of various low-growing plants of the family Acanthaceae, including Diciliptera brachiata, Jacobinia carnea, Beloperone, Siphonoglossa, and Ruellia species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Texan Crescent is recorded against all the insects logged in Big Bend National Park (49 verified sightings from 2019 to 2026), 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.
