Proboscis...

Butterflies get to eat too, and they have a built-in straw that they can use to sip nectar from flowers. It's not easy to get good photos of this part of butterfly anatomy--they usually keep it coiled up under the chin.

But when the butterfly has just emerged from the crysalis, it will usually play around with its proboscis, loosening and tightening the coil, and occasionally extending it...gotta be sure it works OK before heading out.

You can tell by this one's uninflated wings that she's just recently emerged.

Loosening it up a little...

A little later, and the wings are now mostly inflated, and still putzing with the proboscis.

Different butterfly...coiled proboscis.
