The Very Hungry Caterpillar is one of the most illustrative and informative books for children between the age group of 2 to 5 years. The book is basically the story of a caterpillar dissecting the pangs and toils of its life. The language of the book is very simple. This has been especially done so that the children are encouraged to read the book themselves. With its extensive illustrations, the book also provides a lot of information to the children and at the same time persuades them to think and answer some questions; like the number of days in a week or naming food items or stating the stages of evolution of a caterpillar.

Fact and Fiction Balanced Well
The author has given away some really interesting facts in the book in an easy manner which is why the knowledge becomes readily available to the children and they rather take it as obvious facts. While doing so, however, the author has not indulged in scientific facts that become boring after a point and has also emphasized on the fictional things that might amuse the children. Furthermore, the book very accurately states the metamorphosis process which has been endorsed by the Royal Entomological Society.
