Sketch Me A Butterfly

Today's butterfly is called the Weidemeyer's Admiral. They are known for the broad white band that cross the wings.

This butterfly was sketched with a graphite pencil on sketch paper.

So how do you tell a moth from a butterfly?
 
By the antenna.... the butterfly has a thickened area at the tip that makes it look like a club, whereas the moth's antenna are either thread like to the tip, feathery or fringed along the edge.
