Orlando Bloom has spoken out in support of Britain's dwindling butterfly population.
The actor is sponsoring Crystal, the Small Miracle, written by his mum Sonia Copeland Bloom, to help children engage with the natural world.
Orlando - currently filming The Hobbit in New Zealand - said: "Butterflies are powerful symbols of the beauty and vulnerability of nature.
"I am delighted to back Butterfly Conservation and their efforts to ensure that these wonderful insects are conserved for future generations to enjoy.
"The story of Crystal, the Small Miracle ... reflects [my mother's] love of butterflies as well as her passion for children to be educated about the insect world in general."
The book follows the life story of a butterfly and is published by wildlife charity Butterfly Conservation.
Orlando's mother Sonia said: "The transformation of caterpillar to chrysalis and then butterfly is one of nature's greatest miracles.
"After witnessing it myself, I wanted children everywhere to share this incredible experience.
"Too many adults do not appreciate insects and are unnecessarily scared of them and their children can be affected by this.
"Young children usually love little creatures - until they are put off them."
