Remote view of Morpho sp., Rio Ñambi, Colombia

A remote (30m) view of a giant Morpho butterfly warming up in the morning sun of Rio Ñambi, Colombia. They are well know for their giant size (wing span ~20cm), even more for their flashing bright blue (which technically is a result of light reflection, not actual pigmentation).

As the underside of their wings are dark, their rapid wing flapping creates an almost siren-like strobe effect that is impossible to miss. Even pilots are able to see it from the air, reportedly.
