‘The windscreen phenomenon’ - why your car is no longer covered in dead insects
Wildlife experts have been warning about the alarming decline in insects for decades.
An amateur German group called the Krefeld Entomological Society has been monitoring insect numbers at 100 nature reserves in Western Europe since the 1980s. Although there were the annual fluctuations they discovered that by 2013 numbers began to plummet by nearly 80 per cent.
Experts mostly blame intensive agriculture and the use of pesticides over the past 50 years.
Since 2006, beekeepers in Britain have lost about a third of their managed bee colonies each year largely due to the loss of flower-rich grassland which has declined by 97 per cent from the 1930s, and the increased use of insecticides on crops.
“This is part of the wholesale loss of small animals in recent decades. The public know about bees and butterflies, but these are just the tips of the iceberg. Moths, hoverflies, wasps, beetles and many other groups are now sparse where once they were abundant.”
