Phoebis philea, the orange-barred sulphur, is a species of butterfly found in the Americas including the Caribbean. The wingspan is 68 to 80 mm. There are two to three generations per year in Florida and one in the northern part of the range with adults on wing from mid to late summer. The species habitat is in tropical scrub, gardens, fields, and forest edges. Orange-barred sulphurs are often found in large dense groups of mixed species, including the statira sulphur (Aphrissa statira), apricot sulphur (Phoebis argante), and the straight-line sulphur (Rhabdodryas trite). The species eats nectar from red-colored plants.

Possible
About 20% of wildlife watchers report an Orange-Barred Sulphur sighting in Ostional Wildlife Refuge on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 47 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.
June and July
In those months about 30% of wildlife watchers report an Orange-Barred Sulphur in Ostional Wildlife Refuge on a given day, against under 5% in May and August–March, the lowest months. Those are among Ostional Wildlife Refuge's wettest months, with about 420 mm of rain a month against 15 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Orange-Barred Sulphur sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 parks where we can rate Orange-Barred Sulphur sightings, Ostional Wildlife Refuge has the highest daily chance: about 20%. Next come Serra dos Órgãos National Park (Brazil, about 20%) and Lago de Yojoa (Honduras, about 20%).
GBIF citizen-science records
It is estimated from how often the Orange-Barred Sulphur is recorded against all the insects logged in Ostional Wildlife Refuge (11 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.
