A black swallowtail butterfly feeds on a pink cosmos flower. You can see the tongue or proboscis dipping inside the flower, as the butterfly reaches for the nectar at the flower base. Like most pollinators, the proboscis is a tube which functions like a straw as the butterfly sucks nectar from the flower.
