Possibly Walnut Sphinx Caterpillar

This is one of the Sphinx Moth Caterpillars in the family Sphingidae.  Your photo does not have enough detail to make a conclusive species identification possible.  The backward facing horn and the shape of the head indicate this might be the caterpillar of the Walnut Sphinx, Amorpha juglandis.  You can compare your individual to images on BugGuide or Bill Oehlke’s excellent website.  Many Sphinx Moth Caterpillars which are known as Hornworms are capable of making hissing noises when disturbed.
