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.

GBIF citizen-science records
It is estimated from how often the Orange-Barred Sulphur is recorded against all the insects logged in Arenal Volcano National Park (17 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.
