A swarm of bug-related books hits bookstores this spring. Nightmarishly fantastic creatures burst from the pages of Pop-Up Bugs: Creepy Crawlers Face to Face by Sally Hewitt, illus. by Chris Gilvan-Cartwright. These in-your-face pop-ups confront readers in the form of menacing tarantulas waving hairy legs, scorpions with claws extended and wasps that leap out, mandibles and proboscises waving. Accompanying text is equally creepy: ""If you feel on your skin/ A sharp tongue like a pin,/ Then you are probably facing... a mosquito!""
