Schizura unicornis

Mmm-boy! This redbud,(Cercis canadensis) is delicious.

Correct. The red bud is delicious. Otherwise, this herbivore, (Schizura unicornis), would be eating up something else.

So far, studying insects, I have found no greater contrast between a moth and its caterpillar than this example. Also, careful observation indicates a bifurcated horn. Does the adult moth have a single horn somewhere?
