While the number of fireflies has remained steady this summer compared with last year, overall numbers of these bugs have decreased by about 35 per cent over the last five decades, Fairweather said. “It’s really sad to see that one of these childhood marvels _ these insects that make us say, ‘Isn’t the world incredible?
