this Ministrymon, photographed in the mangrove at las Peñas by Julia Wittmann, is a difficult case
although almost white it looks nevertheless like Ministrymon una, a species which, according to butterfliesofamerica, flies from México to Brasil, up to an altitude of 1000 m, hence normally not a mangrove species.
Julia tells us this butterfly was rather common on a 31rst of august, so, if anyone (con permiso de colecta) passes near las Peñas, it would be a great idea to collect a few specimens.
