Messico. Yucatan. Blue Morpho, Morpho helenor: una enorme farfalla azzurra.




Uno degli hotel era molto isolato, lungo una via che attraversa il centro dello Yucatan, con chilometri di jungla intorno. Due giorni con incontri in giardino come questo: un fazzoletto azzurro in volo, bruna farfalla quando si posa. Immensa.

Tra le varie Blue Morpho mi pareva questa:

Morpho peleides
        
Peleides Blue Morpho
Scientific classification
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae
Genus: Morpho
Species: M. peleides
Binomial name
Morpho peleides
Kollar, 1850
The Peleides Blue Morpho, Common Morpho,[1] or The Emperor[2] (Morpho peleides) is an iridescent tropical butterfly found in Mexico, Central America, northern South America, Paraguay, and Trinidad. Many authorities[which?] believe that peleides is a subspecies of Morpho helenor.
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).
