Habitat loss, pesticide use and, surprisingly, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species and related impacts on biodiversity and ecotourism, according to a Tufts University-led team of biologists associated with the International Union for the Conservation of Nature.
Habitat loss, pesticide use and, surprisingly, artificial light are the three most serious threats endangering fireflies across the globe, raising the spectre of extinction for certain species and related impacts on biodiversity and ecotourism, according to a Tufts University-led team of biologists associated with the International Union for the Conservation of Nature.
Fireflies belong to a widespread and economically important insect group, with more than 2,000 different species spread out across the globe. To better understand what threats are faced by fireflies, the team led by Sara Lewis, professor of biology at Tufts University, surveyed firefly experts around the world to size up the most prominent threats to survivial for their local species.
Their perspective piece, published today in Bioscience, sounds a warning bell about the insects’ future, highlighting specific threats and the vulnerability of different species across geographical regions.
According to survey respondents, habitat loss is the most most critical threat to firefly survival in most geoographic regions, followed by light pollution and pesticide use.
