That's it for the guides! From this point on, press harder with your pencil for a more defined drawing of a tiger swallowtail butterfly.

Step 6: On top of the first oval, draw a very small arc for the tip of the butterfly's head. On either side of the tip of the head, draw a small, curved line for the eyes. Darken the top of the initial oval to create the rest of the head. Use a series of short strokes to draw the outline of the swallowtail's head for a fuzzy texture. On the tip of the head, draw two long lines for the antennae. Make the tips of the antennae a bit thicker than the bottoms. Make the antennae the same length. They should be farther apart at the top.

Step 7: Darken the rest of the first oval to complete the shape of the tiger swallowtail butterfly's thorax. Use a series of short strokes as you follow the path of the guide for a fuzzy texture.

Step 8: Use the big, triangular shapes at the top as guides to draw the forewings. Darken the top and bottom lines but make the sides and corners curvier. As you darken the outer edges of the shapes, use wavy lines to give the wings a more organic shape. Make both forewings the same so that they're symmetrical. The top corners of the wings on both sides should be curvier than the initial guide lines. Make sure that the outer edges of the forewings are wavy and the inner edges are flat.

Step 9: Use the big shapes at the bottom as guides to draw the butterfly's hindwings. Darken the shape on the lower, left side but use wavier lines as you follow the path. At the bottom, draw a thin, long shape to give the wing the "swallowtail" shape. Use wavy lines as you darken the left edge of the guide. Make the wavy lines curvier than the inner edge. Use the shape on the right to draw the tiger swallowtail's other hindwing the same way. Just follow the shape of the guides and make the lines wavier as you darken the path. On the bottom, draw a thin, long shape to give the hindwing the "swallowtail" look. Finish the shape of the wing by using wavy lines along the right edge of the guide.
