Abstract
The immature stages of Morpho macrophthalmus (Fruhstorfer) and Morpho peleides telamon (Rober ) from Western Colombia are described and compared for the first time, along with morphological and natural history notes. M. macrophthalmus has long being considered as a good species by several authors, however in this comparative study of immalture stages between the two species we provide morphological and biological evidence that both taxa belong to the same species (M. helenor) indeed, in some places along the western Cordillera such as the upper Calima river where the natural populations of the two taxa overlap it is possible to find natural hybrids that produce intermediate lorms. Illustrations and descriptions of immature stages of hoth taxa are provided.
