frenzied beetles upset apple cart

Climate change could be throwing common tree killers called mountain pine beetles into a reproductive frenzy. A new study suggests that some beetles living in Colorado, which normally reproduce just once annually, now churn out an extra generation of new bugs each year. The insects, says Jeffry Mitton, an evolutionary geneticist at the University of Colorado, Boulder, were swarming close to 2 months too early that year.
