Hawk moths aren't the most svelte or slender fliers. But when you can unfurl a 14-inch long proboscis, who cares? Like nectar bats, many species of hawk moths (sometimes called sphinx moths) can reach nectar inaccessible to other flying creatures. Instead of keeping their appendages tucked deep inside, though, the moths keep theirs curled up until they need them.
Famously, Charles Darwin predicted that there must have been moths with exceedingly long proboscises in Madagascar after he saw the orchids from that island with deeply recessed nectar. Those moths weren't discovered until after the great naturalist's death, so he was posthumously proven correct.
