Panacea prola amazonica
 
Panacea prola, the prola beauty or red flasher, is a species of butterfly of the family Nymphalidae. It is found from Costa Rica to southern Brazil, but is most common in the foothills of the eastern Peruvian Andes. The wingspan is 65–75 mm. The underside of the hindwings is bright red without markings.   The genus Panacea contains 3 known species, all confined to the neotropics.
The underside hindwings of all Panacea species are reddish. In procilla the ground colour is reddish brown, overlaid with broken wavy black lines and a series of submarginal ocelli. It also has reddish maculae in the forewing discal cell. In prola the underside is bright red and without ocelli. Both prola and procilla have red maculae in the underside fw discal cell, but these are absent in regina.
The iridescent bands on the upperside of all Panacea species are a highly reflective pale turquoise colour when viewed from directly above in bright sunlight. In overcast conditions, when viewed at certain angles, the colour changes to a beautiful shade of sky blue.
Panacea prola is found throughout much of South America, from Colombia to southern Brazil but is more abundant in the foothills of the eastern Peruvian Andes than anywhere else.
