Lightening Bugs Are Thriving In Pennsylvania But Not Elsewhere

The iconic bug of summer: lightening bugs;, are disappearing across the country. But they are thriving in Pennsylvania.  Kelli Hoover, a Penn State Entomology Professor, says there's no doubt there are far more fireflies this year in the state but in general (across the nation), their population is declining. Hoover said the demise of the firefly, popularly known as lightning bugs, can be traced, in part, to pesticide use and the loss of lush vegetation where they flourish. But Pennsylvania - with unusually mild winters in recent years and plentiful rainfall - is the perfect home for the glowing bug. That's according to an associate professor of entomology at the University of Florida who has spent 20 years studying fireflies.
