Leptophobia aripa, the common green-eyed white or mountain white, is a butterfly in the family Pieridae. It is native to Mexico, Central America and South America, but strays may be found as far north as southern Texas. Leptophobia aria is very selective of the host they choose to lay their eggs in. [1]
It is a multivoltine species with overlapping generations. Adults feed on flower nectar of various species, including Emilia sonchifolia, Lantana camara and Bidens pilosa. The larvae feed on Brassicaceae species, including Brassica oleracea. Other records include Nasturtium officinale, Tovaria pendula and Tropaeolum moritzianum. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green-Eyed White is recorded against all the insects logged in Cumbres de Monterrey National Park (60 verified sightings from 2019 to 2026), calibrated against known sighting rates.
