Then cut each piece so you have eight more-or-less-equal wedges.
I like to make the uncut part about 1/3 the way down the outside edge, it makes the butterflies look a little more realistic.
You could get really fancy and creative here, if you have the time and inclination. Strings of licorice would also work for antennae, but kinda defeats the purpose of the healthy snack. (Besides, you know what happens once a package is opened...)
You could also decorate using raisins, other dried fruit (think colors here), mini chocolate chips, colored sprinkles, even paint on the wings with diluted food color, or a finger dipped in a natural color-- cocoa powder, blueberry juice, turmeric or curry powder, crushed safflower, dried powdered beet or tomato.
