This is a very good introduction to insects for anyone who is interested in these fascinating creatures.
The book is clearly written and beautifully illustrated with line drawings and photographs. It's also fairly comprehensive, covering everything from how insects breathe, to how they reproduce, their biology at a cellular level, different groups of insects and issues around conservation. It also includes fascinating details such as the location of an unexpected colony of Monarch butterflies; the strange connection between the large blue butterfly and a species of ant and the insect species that look after their young.
I also like the way the book is divided into very short sections so that you can read a bit at a time.
I wholeheartedly recommend this book if you want an introduction to how insects work. It is definitely an introduction though, and may well leave you wanting to find out more!

If you're interested in insect emotions, there's an excellent article on the BBC Future website 'Why Insects are more sensitive than they seem'.
