This tube is called a Proboscis and is actually two tubes.
When the butterfly emerges from it's pupa the two separate tubes need to be 'zipped' together for the proboscis to work properly. If the butterfly is unable to do this, it will die.
Once the proboscis is working the butterfly seeks out food, or energy. Butterfly food can be flower pollen, tree sap, plant juices that are sweet, rotting fruit, dung (usually bird) and even carrion, or the decaying flesh of animals.
The butterfly excretes enzymes through the proboscis that breaks food down allowing it to be sipped up into this straw-like tube. Because butterflies also require minerals and salts, they 'puddle' in water and even urine for these.
The buterfly uses its tongue, often a long tube, to drink.
The proboscis is the coiled, tube-like appendage on butterflies and some other insects. When the butterfly wants to drink nectar, it uncurls the proboscis and uses it like a straw to suck up nectar from flowers.
Butterfly is dependent on flowering plants for nectar
Tube worms shoot silky looking netting onto coral, which makes fish tanks very unattractive. Copperbanded butterfly fish will usually eat tube worms. Wrasse and Dottyback fish will also eat tube worms.
The organ or body part that the butterfly uses to eat food is the proboscis. This is what they use to drink or suck nectar from flowers and plants.
A butterfly uses it's mouth to eat nectar from the center of a flower. While eating, pollen gets on the butterfly's legs. When he travels to the next flower, the butterfly ends up inadvertently pollinating it.
Insects such as the mosquito and butterfly use tiny tube-like mouth to eat. The only food both tend to eat is fluids from plants and animals.

Butterfly Fish eat tiny shrimp, worms, and algae.
I'm pretty sure it is Aeropostale that uses the butterfly logo...but I'm not so sure any designer uses it. :-)
The butterfly's sipping tube that coils and uncoils is called a proboscis, verterbrates, and inverterbrates can have these like the elephant. A proboscis is an appendage from the head of an animal. : )
