The Morpho Menelaus' characteristic iridescent wings has a unique wing structure. The ground scales are covered by a set of longitudinal ridges, and within the ridges are layers of lamella. [ 12 ] Because the size of the microstructure is the same as the wavelength of light, the layers in the wings react strongly with visible light. [ 2 ]
Iridescent colors of Morpho butterflies are caused by the specific nanostructures on their wings (SEM image at the bottom). [7] Many morpho butterflies are colored in metallic, shimmering shades of blues and greens. These colors are not a result of pigmentation, but are an example of iridescence through structural coloration.
The brilliant blue color in the butterfly's wings is caused by the diffraction of the light from millions of tiny scales on its wings. It uses this to frighten away predators, by flashing its wings rapidly. The wingspan of the blue morpho butterfly ranges from 7.5–20 cm (3.0–7.9 in).
Both the presence of fluorescent pigments in their wings and the nanostructure of their wings are responsible for the iridescent fluorescence of M. sulkowskyi. The major blue fluorescent pigment contributing to the fluorescence of M. sulkowskyi was found to be L- erythro biopterin, along with minor components of pterin and isoxanthopterin.
M. d. granadensis C. & R. Felder, [1867] (Nicaragua, Panama, Colombia, Ecuador, Venezuela) Upper surface similar to Morpho peleides, but the black distal border considerably more extended, the wings more rounded, the Morpho reflection deeper blue, and especially characterized by its large, light cinnamon-brown ringed ocelli, those on the ...
Morpho catenarius has a wingspan of about 75–100 millimetres (3.0–3.9 in). This species lacks the usual bright blue coloration of many Morpho species. The translucent surfaces of the wings vary from a pale blue color to almost white. The edges of the wings show a series of black spots, while the hindwings are crossed by several small "eyes".
The genus Morpho is palatable but some species (such as M. amathonte) are very strong fliers; birds – even species which are specialized for catching butterflies on the wing – find it very hard to catch them. [1] [2] The conspicuous blue coloration shared by most Morpho species may be a case of Müllerian mimicry, or may be 'pursuit ...
Morpho telemachus is a large butterfly. The upperside of the forewings is a silver grey and blue green with a very wide black-brown outer edge. This is also on the posterior wings and can even cover almost all of the hindwings and forewings.
