Start all insects with a shell by drawing a round or oval base shape over a straight line. The symmetrical details surrounding the body will help you differentiate between insects.
To draw a beetle, draw a straight line and place an oval on top that represents the back and the head.
Add lines for legs and draw the details of the head.
Draw the contours of the body. Thicken the legs and fill in the last few details.
In flight, the beetle takes its wings out from under its shell. Seen from above, a beetleās wings are always symmetrical.
When drawing a ladybug at a three-quarter angle, its back will look like it is bulging out. So, draw the central straight line curved along the body.
In this perspective, one of the back legs is no longer visible.
Small beetles come in an infinite variety. The basic idea remains the same; what changes is the proportion between the head and back, and, of course, the details and patterns.
