How do animals survive in the burning sun on the hottest days of the year? A brief tour through a variety of ecosystems offers a glimpse of how several creatures native to each deal with the heat. In a field, a woodchuck goes to a den below ground, an earthworm curls up tightly in its underground tunnel, a spittlebug creates a “foamy home,” while a black swallowtail caterpillar “keeps chomping and chewing all day long.” A desert, a wetland, and a seashore (including things happening beneath the water) are the other places where the featured creatures live. A finely crafted informational narrative is set against realistic illustrations of the natural world. Highly Commended, 2015 Charlotte Zolotow Award (Ages 5–8)
