American Snout

I had another good butterfly in the park this morning.  An American Snout.  I don’t see many snouts but have seen them in the park a few times. By looking at the picture it’s obvious why they are called snouts.

The ‘snout’ is actually sensory structures called labial palps on either side of the proboscis.   You can see them on other butterflies with closeup pictures. On this butterfly they are extreme. Or maybe, extremely extreme.
