Pipe tip 3 dots on wings using full-strength royal icing. Paint three lollipop sticks with brush dipped in black icing color; insert in craft block to dry. Make ends for stinger and antennae. On waxed paper pipe tip 12 balls, 1 in. diameter, in royal icing; let dry. Top each ball with tip 3 swirls in royal icing. Attach balls to black lollipop sticks with royal icing; let dry.
