Backyard volunteers helping track firefly numbers
INDIANAPOLIS – The yellow-green streaks of fireflies that bring a magical air to summer nights, inspire camp songs and often end up in jars in children's bedrooms may be flickering out in the nation's backyards as suburban sprawl encroaches on their habitats.
Scientists concerned by reports from the public that they are seeing fewer of the luminous insects each summer have turned to a network of backyard volunteers spanning much of the nation to track their range and numbers. Their observations may shed light on whether fireflies are indeed declining — a trend that could dwindle the targets for the childhood rite of passage of chasing fireflies.
As this weekend marks summer's unofficial end in America, the Firefly Watch volunteers' work is winding down now that the insects' annual light show is over in all but southern states.
