As the summer holidays begin, the Bugs Matter 2024 survey, led by Buglife and Kent Wildlife Trust, is calling on citizen scientists across the UK to participate in this insect population study.
Since the first reference survey in 2004 led by RSPB, analysis of records from nearly 26,500 journeys across the UK shows a continuing decrease in bug splats, with the number of splats sampled on vehicle number plates by citizen scientists decreasing by 78% nationwide between 2004 and 2023.
“We’re at a critical juncture in the 2024 survey season,” said Paul Hetherington, Buglife Director of Fundraising and Communications. “The summer holidays present an ideal opportunity for families to contribute to this important citizen science initiative while on their travels. Many people are noticing fewer insects this year so please collect more data over your summer break to help us understand the situation better.”
The 2024 survey began on 1 May, and since then 5,292 journeys have been logged, covering an impressive distance of 146,291 miles, showcasing the collective effort of citizen scientists across the UK to collect valuable scientific data.
Each journey recorded represents a vital contribution to our understanding of insect abundance and the data will help to inform better conservation policy and practice to save our bugs.
Dr Lawrence Ball, Kent Wildlife Ecological Data Analyst Lead shares: “Notably, participants in the South East have emerged as the front runners, having logged an impressive 1,279 journeys over the survey period so far. The East of England and Scotland are not far behind with 1,068 and 472 journeys, respectively, but there is still time for these regions and others to overtake before the end of September!”
A noticeable lack of insects across the UK this summer has been the subject of much discussion across many social media platforms and discussion groups; with individuals and conservation groups expressing their fears about our future if we don’t take action for insects now.
A number of wildlife rescue and rehabilitation charities have recently come forward with anecdotal observations linking to possible declines in insects too. Bat conservation groups across Cambridgeshire, Norfolk, Worcestershire, Essex and South Lancashire have said that they are seeing an increase in the number of “starving” or “underweight” bats, often juveniles, who need to be rescued and cared for by volunteers. In some places, they are seeing fewer bats than they usually do in the summer.
Similarly, Oxfordshire Wildlife Rescue recently shared that “This year has been a true ‘eye-opener’ into the ‘issues’ regarding the lack of insect life and the weather patterns. The direct impact on insectivores/garden birds across various species has been all too clear: failed nestlings, abandoned nests/broods, and emaciation cases. As well as garden birds, we have taken on the care of 16 juvenile swifts, and many of these admissions have been emaciation cases.”
Conservationists are expressing that several factors may be contributing to the lack of insects, including habitat loss, pesticide use, light pollution, invasive non-native species and changing climate, and the knock-on effects on other species. Many experts are also advising that the unusual weather conditions of the last two years are an exacerbating factor. With a prolonged wet spring, and colder than usual summer conditions, many insect breeding cycles will have been impacted.
Dr Lawrence Ball emphasises the need for more research: “While these theories are plausible and anecdotal observations are valuable, we need robust data to understand the full picture. That’s why every contribution to the Bugs Matter survey is vital.”
The 2024 survey ends on 30 September 2024. Families, friends and individuals are encouraged to take part in the survey as part of their summer holiday activities. Further details on supporting Bugs Matter can be found at buglife.org.uk/get-involved/surveys/bugs-matter/
