Step 10: Draw a curved line under the blue morpho's eyes for the bottom part of the head. Add an M-shaped line between the eyes at the top for the second part of the butterfly's head.
Step 11: Draw two long curved lines on top of the head for the blue morpho butterfly's antennae. Try to make these lines mirror images of each other.
Step 12: Use wavy lines as you follow the basic path of the initial oval to create the shape of the blue morpho's thorax.
Step 13: Use the initial curved line as a guide to draw the blue morpho butterfly's abdomen. Follow the basic path but make the lines wavier.
Step 14: Use the initial series of lines at the top as guides to draw the outer shape of the forewings. First darken the top curved edge and the lower edge of the guide lines. When you darken the sides of the forewings, use a wavy line as you follow the basic path of the guide. Try to make the wavy sides as similar as to each other as you can to give the butterfly's wing symmetry.
