There are many strange objects locked away in the museum stores.
But this is one of the strangest.
It's known as Darwin's Sphinx moth from Madagascar.
Darwin didn't know anything about the moth to start with.
He was working on pollination in orchids,
and he was sent some orchid flowers,
and among these was this Madagascan Star Orchid.
The orchid had an extraordinarily long tube.
Darwin deduced
that the only creature in Madagascar
that could pollinate this flower was a type of hawk moth.
One with a tongue long enough to reach 30 centimetres down to the nectar.
He knew of no example of a moth
that had a long enough tongue to pollinate this.
But he made a prediction
that such a moth would one day be found.
