"This lushly illustrated ecological tale rests on the premise that readers are camped in a Central American rainforest to observe an army ant swarm. Chrustowski's close-up, realistic illustrations, comprised of multiple layers of colored pencil over watercolor wash, are vivid and effective, with the ants often appearing to be heading straight toward readers. Eye-catching and clearly written, this title ... will be a useful addition to most collections." — School Library Journal
