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.

With luck
About 10% of wildlife watchers report an Orange-Barred Sulphur sighting in Tenorio Volcano National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 98 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Orange-Barred Sulphur is recorded against all the insects logged in Tenorio Volcano National Park (10 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.
