Declining insect numbers will increase food bills, scientists warn
Decreasing the number of insects will increase food bills

The number of flying insects has dropped by almost 60% in less than 20 years, a new alarming study has found. The Great Depression threatens our entire ecosystem, scientists have warned after the study - but we can still turn things around.

What do the survey results show?

Using data uploaded by members of the public through the Bugs Matter app, scientists from the Buglife Conservation Faith counted the number of 'splatter' defects on car license plates across the UK. The researchers compared the results from nearly 5,000 trips in the summer of 2021 with a similar study from 2004. The findings were extremely troubling.

In England, the number of printed insects fell by 65%. Wales data showed a 55% decline, while Scotland recorded a 28% decline. The results reveal "huge losses," warns Buglife Director of Communications and Fundraising Paul Hetherington. Habitat destruction, pesticide use and climate change have all contributed to the Great Depression.

Why does declining insect numbers matter?

Flying insects are critical to biodiversity. Insects are food for animals such as birds, bats, reptiles and fish. They also perform vital roles such as pollination of wild crops and flowers and recycling of nutrients. Families of beetles, wasps and dragonflies also act as predators for smaller insects that help control pests.

If they are extinguished, the whole ecosystem and food production system - would suffer. The environmental effects would also be catastrophic. If insect decline does not stop, eight out of ten wildflower species in the UK could become extinct. Most songbirds would die, with only four or five species able to survive without healthy insect populations.

What can we do to reverse these declines?

The survey makes for sober reading, but it is not too late to save the flying insects. Governments also have a major role to play and can limit habitat loss and reduce the massive use of pesticides. But individuals can also play their part. Letting the grass grow tall and planting wildflowers in the gardens are essential to help increase the insect population.
