Ten little caterpillars make their way through the world as enumerated in this simple story. One wriggles up a flower, another climbs a cabbage head, and yet another is taken off to school inside a jar. The last in the series achieves its goal after it “scaled an apple tree … / and hung there patiently … / until by and by, the tenth little caterpillar … / became a butterfly.” Ehlert’s trademark vibrant watercolor collage illustrations meticulously document each insect’s activity, and in five concluding pages identifies the ten types of caterpillar and what each eats, and shows all in both larval and butterfly forms. (Ages 18 months to 4 years)
