From Karla Kuskin's ""Bugs"" to Margaret Wise Brown's, here are 20 ""Poems About Bugs and Other Crawly Creatures,"" many of them already familiar. The selections range from lyrical to doggerel; what they have in common is the popular appeal of their subject and a fresh, childlike point of view. Palagonia's realistic art, colorful if a bit stolid for such ethereal creatures as dragonflies, is enhanced by the open format and generous use of white space. A succinct verse by Benjamin Franklin (""What is a butterfly?/At best/He's but a caterpillar/Dressed"") is a nice touch, surprisingly revealing of its author's interests and sense of humor. Useful.
