Morgan's sphinx moth
Morgan's sphinx moth is a very big moth with a very, very long tongue. It keeps its tongue rolled up like a garden hose and unrolls it to drink nectar from deep inside flowers. Long before anyone had seen it on Madagascar, a famous scientist guessed that a moth like it had to exist.

How fast is it?
Fun facts
Charles Darwin saw an orchid whose nectar sits at the end of a tube 20 to 35 centimetres long, and guessed there must be a moth with a tongue long enough to reach it.
Another scientist, Alfred Russel Wallace, guessed it would be a sphinx moth. When the moth from Madagascar was found, it was given the name praedicta, which means predicted.
To drink, it backs away from the flower, unrolls its tongue and then flies forward to slide it in.
On Madagascar, the boy moths can make clicking sounds too high for us to hear, which confuse hungry bats.
It helps baobab trees on Madagascar make seeds by carrying their pollen.
