I’ve seen this large daytime moth several times in my garden & house and the only other place was at Esquinas Rainforest Lodge near Golfito on the Pacific Coast. The other day I saw two, one on my Cecropia Tree and another injured one hiding among plants in my garden. When not wanting to be seen, they are this plain beigey brown color with off-white spots and bars. But when they fly or lift their forward wings, the hindwings are a bright orange and white. You can see this from earlier sightings in my GALLERY: Giant Butterfly Moth, Castniomera atymnius (linked to the gallery). Just two shots here from this November sighting.
¡Pura Vida!
