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 →

Possible
About 20% of wildlife watchers report a Texan Crescent sighting in Saguaro National Park on a given day, based on 185 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 354 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.
March–April and October
In those months about 30% of wildlife watchers report a Texan Crescent in Saguaro National Park on a given day, against under 5% in August, the lowest month. Those are among Saguaro National Park's driest months, with about 20 mm of rain a month against 55 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Texan Crescent sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 parks where we can rate Texan Crescent sightings, Saguaro National Park ranks 3rd at about 20%. The best odds are in Cabo Pulmo National Park (Mexico, about 30%) and Bahía de Loreto National Park (Mexico, about 30%).
Same family: Nymphalidae
The closest relatives of the Texan Crescent that you can see in Saguaro National Park (family Nymphalidae, Brush-footed Butterflies) are Queen (about 40%), Empress Leilia (about 30%) and American Snout (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Texan Crescent is recorded against all the insects logged in Saguaro National Park (185 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.
