Step 6: Draw a diagonal line on either side that connects the previous lines to complete the guide for the blue morpho butterfly's forewings.
Step 7: Draw a short diagonal line on either side of the body, under the lower edge of the forewings, as a guide for the first part of the hindwings. Then draw a longer line with a more vertical orientation on either side of the body for the second part of the guide for the hindwing. These longer lines should be closer to the butterfly's body. Remember to make the side as symmetrical as possible.
Step 8: Draw a long curved line on either side of the body that connects the previous lines as a guide for the lower edge of the hindwings. When you finish, check your blue morpho butterfly sketch for symmetry and fix anything that stands out. It doesn't have to be perfect. Just tweak any major inconsistencies.
That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.
Step 9: Draw two small half-circles inside the head for the compound eyes. Butterflies have big eyes, so they should take up a lot of room inside the head.
