A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides

The rapid decline of Earth’s most numerous animals is a major threat to the biosphere

The number of insects splattered on vehicle number plates in Britain fell by 64% between 2004 and 2022, according to a survey. Each summer citizen scientists record the number of insect splats on their number plates on an app after a journey. The latest Bugs Matter report, produced by Kent Wildlife Trust and Buglife, found another drop in 2022 compared with 2021, with the long-term decrease jumping by five percentage points.

Small patches of land given over to wildlife-friendly planting can make a big difference to pollinator conservation, a new study suggests. Bee and other pollinator populations in Europe and North America are in decline due to a range of factors including habitat loss and insufficient flowers for food.

Recent studies from around the world show insects are disappearing fast. If this continues, this will have profound consequences for mankind and for our planet, for insects provide a myriad of vital ‘ecosystem services’, such as pollination, pest control, decomposition and recycling. This lecture looks at the causes of this crisis, at possible solutions including more sustainable farming systems, and at what we can do individually to create insect-friendly habitats.

An international study on the future of insects under climate change scenarios has found the loss of insects will drastically reduce the ability of humankind to build a sustainable future. "A growing body of evidence shows many populations of insects are declining rapidly in many places. These declines are of profound concern, with terms like an emerging 'insect apocalypse' being increasingly used by the media and even some scientists to describe this phenomenon," Laurance said.

It may take bees multiple generations to recover from being exposed to insecticides even just once, research shows. A new research, published in PNAS, shows that even a single exposure to insecticides in a bee’s first year of life affects offspring production, and since the effects of the pesticides are cumulative, this results in an overall decrease in population

Fried crickets on the school menu, milk made from fly larvae and mealworm bolognese for dinner? These are the environmentally friendly meals we can look forward to. Bon appetit!

Light pollution is a significant but overlooked driver of the rapid decline of insect populations, according to the most comprehensive review of the scientific evidence to date.Artificial light at night can affect every aspect of insects’ lives, the researchers said, from luring moths to their deaths around bulbs, to spotlighting insect prey for rats and toads, to obscuring the mating signals of fireflies.

LEDs used in streetlights typically emit white light, while sodium lamps have a characteristic yellow glow – as seen in the picture below. This change in the colour of artificial light is predicted to have major consequences for wildlife.

Insects have declined by 75% in the past 50 years – and the consequences may soon be catastrophic. Biologist Dave Goulson reveals the vital services they perform
