NIGHTTIME AND DAYTIME BUTTERFLIES 3+ is a coloring book combined with narrative content, for preschool children. Inside, the most beautiful butterflies found in nature are illustrated, but also the rarest, the smallest, the daytime and the nocturnal ones. Each butterfly is associated with its caterpillar and a schematic and easy-to-read fact sheet, which accompanies young readers to discover its characteristics: where it lives, what it eats, where it migrates and what it likes to do.
