That's it for the guides! From this point on, press harder with your pencil for a more defined drawing.
Step 6: Use the long, curved line at the top as a guide to draw the Hercules beetle's first horn. Make the line darker. The left side of the line should be flush with the top side of the circle. Lightly sketch another curved line underneath to make the shape thicker. Make the base wide and the tip narrow. Close to the left side, draw a small, V-shaped line for a small bump on the bottom of this rhinoceros beetle's horn. When you get the shape of the horn right, darken the lines. Make the tip on the right pointy. The horn should be pretty thin except for the wide base on the left.
Step 7: Use the initial circle to draw the rest of the horn's base located on the thorax. Draw an angled shape within the initial circle for the base of the Hercules beetle's horn in the thorax. Leave a space between the bottom of the base and the bottom of the initial circle.
Step 8: Use the long, horizontal line at the bottom as a guide to draw the bottom horn in a similar way. Darken the line but curve the left side up a bit to form the Hercules beetle's head. Lightly sketch a line above to make the shape thicker. Make the base on the right wider than the tip on the left. Draw a couple of bumps along the top edge. Draw two bumps on the left and two on the right. When you get the shape right, darken the lines.
Step 9: Inside the beetle's head, draw a small circle for the eye. The base of the top horn should cover the eye slightly. Below the head, draw a small, thin shape that angles to the right for the first part of the antennae. To the right draw a smaller, thin shape for the antenna on the other side of the Hercules beetle's head.
