The crystal-clear wings are suffused blue or iridescent pink.

Morpho lympharis replaces M. portis in the Andean region, but has hitherto only been found in Peru and was described from Paucartambo Province.

The male above are somewhat darker blue than M. aega and with subapical white punctiform spots on the forewing.

The underside of both wings is decorated with three ocelli, of which the apical and the two intermediate ones are elongate-oval in shape.

Lamas (2004) considers that there are two species, M. sulkowskyi ranging from Colombia to central Peru, and M. lympharis, ranging from central Peru to Bolivia.
