One of the most famous butterfly in Costa Rica, due to its beautiful iridescent blue colored inner wings. Not so fortunately for us, this one was sleeoing so it showed us its external side of the wings which may be less flashy but also very beautiful. Morphos are big butteflies: their wingspan ranges from 7.5–20 cm (3.0–7.9 in).The brilliant blue color in the butterfly's wings is not a mere beauty display!. It is caused by the diffraction of the light from millions of tiny scales on its wings and the buttefly uses this to frighten away predators, by flashing its wings rapidly. (The eye-like designs in the other side of the wings are also thought to be used to confuse and scare predators in these and other butteflies.)
Tropical rain forests in Central America. We have seen them in the Monteverde and Santa Elena reserves too. This one was in the Buttefly Garden of Monteverde.
