two tongue butterfly ;)

With roltong butterflies sucking nectar from the plants. It consists of two twisted towards each other, hollow tubes.
When the butterfly comes from pop, these tubes are unrelated. They must first be rotated to each other in the tongue may be used.
The tongue must be very long to deep into the flower tube to suck the nectar.

as I read on a dutch butterflywebsite wondering why this one has two roltongs
