Darwin's orchid, Palmarium, Madagascar

Had I known how special this species is, I would have taken more time to capture it properly. It has a cool story attached to it.

This orchid has an extraordinarily long spur, which seemingly makes nectar almost impossible to reach by any pollinator. Charles Darwin himself tried to replicate the process using man-made tools like needles, and failed. Something longer and thinner would be needed to pollinate this.

He predicted that a moth had to exist with a 35cm(!) long proboscis, a moth yet to be discovered at the time. He was ridiculed for this prediction, as nothing even remotely similar to such a creature was known. Instead, it was to be a "divine" creation.

Sadly, Darwin did not live to see his prediction turn true, here's the moth:

And here's a guy waiting at night to see the pollination in action:
