More fireflies than usual are lighting up summer evenings in the U.S. Northeast. But scientists say the lightning bugs are still on the decline. A particularly wet spring may have created the ideal conditions for young fireflies to grow into adults and set summer nights aglow. There are over 2,000 known firefly species across the globe. While evenings in the Northeast may seem brighter this summer, the bugs are actually waning at a faster rate than ever before. To look out for fireflies, consider turning the lights off at night and avoid spraying front lawns with insecticides.
