Realistic insects pencil drawings

Insects have the largest number of species in nature.

The first step in drawing insects, in a realistic style, is planning (choosing a subject) and composition.


If you do not have any experience with realistic drawing, you might want to read my guide for realistic pencil drawing first.


Composition tip:

Although they are easier & faster to draw, in most cases, try to avoid side views:

Note that because I am right-handed, I draw from left to right (so I do not smear what I already drawn):

It is more interesting for the observer to see insects (or anything else) with an angular view.

The housefly is attracted to the human food and exposed parts of their body, thereby passing on pathogens that it carries on its body.

Front or top views are like side views. Meaning, less interesting.

Basic drawing steps:

To draw any insect, start by drawing its form (structure) accurately.


Draw the lines gently, so you can draw over them or erase them. There are no lines in nature, so we do not want lines in our final drawing.

Drawing the outlines first

I usually prefer to draw the background layer first (in this case, the plant stem).

Pay attention to brightness values and edges.

Drawing the background stem

While the body of (most) insects has hard edges, the shadows will have soft edges.

Aphids are destructive to plants (sap-sucking).


Ladybugs prey on aphids.

If you struggle with accuracy, here is how to draw from photos (from observation).



Bees have an important ecological role in pollinating plants but their number is getting smaller and the cause is unclear.

Planting flowers rich in nectar and avoiding the use of spraying materials in planters or in the garden.



Ants follow chemical traces left by a scouting-ant when it finds a food stock.

The female mosquito, when it needs proteins for its eggs, is looking for a live source to suck blood from.

In the case of an occasional mosquito, it is recommended to use an electric bat.

How to draw transparency?

Some insects' body parts, especially wings, can have different levels of transparency.

To draw that, we look at the brightness value of anything behind the transparent part.

In the example below, the cockroach wing is semi-transparent. The area behind it is quite light except for the leg, which has a darker value.

In addition, we pay attention to edges located below the transparent surface.

In the example above (and below), the edges (of the leg part that located under the wing) are both soft AND distorted (less defined).


For insects with fully transparent wings, there may be no distortion to edges.

Cockroaches can live without food for several days to a month, thus even if you do not see them at home, that does not mean they are not there!


Ensure the house is clean and, if necessary, spray pesticides in the area in which they are located.



There are too many insects!

Spiders (which are not insects) eat many insects.

Most spiders are harmless to humans, so it is best to let them do what they do best.

What is the importance of insects?

Ecological importance:

Economic importance:

Insects as food:



Flies and mosquitoes have great ecological importance and are the second most important pollinators after the bees.

Mosquitoes are the most lethal family of animals because they transmit parasites and viruses.

The cockroach has a high resistance to radiation but has no exceptional resistance compared to other insects such as the fruit fly.
