The Fire Bug Connection — Jean Craighead George

Mutant Bug!

"When a raven, flies at you, there will, be a murder." That's what Maggie's grandmother once told her, and the longer twelve-year-old Maggie stays with her parents at the Biological Research Station--or Bug Camp, as she calls it--the more she believes it. Soon after a raven's appearance, something strange happens to Maggie's beautiful new fire bugs. Instead of molting into the next stage, the bugs grow grotesquely large and seem to be doomed. Is global warming the culprit? Acid rain? Or...murder? One thing is certain--it's an eco mystery, and Maggie, with the help of Mitch, a young computer whiz, must try to track down the killer.
