Caterpillar and bean

"What's that wedged in a crack in the ground, small and hard and wrinkly and brown? A bean seed! Soon it develops roots and leaves. And what's that on the leaf? An egg! The egg hatches a caterpillar, and the caterpillar eats the leaves, getting bigger and bigger until it forms a chrysalis. Meanwhile, the plant is growing, too: it develops flowers, then bean pods, as it reaches up toward the sun. Side by side, plant and insect grow . . . and grow . . . and grow throughout the year, until they come full circle."--Publishers website.
