Bugs Matter on a Glider

A unique collaboration between Kent Wildlife Trust and Essex & Suffolk Gliding Club.

Insects face mass extinction. They are a critical component of ecosystems and animal life is at risk. However, there is a need for more data to fully understand what is happening. Bugs Matter is an national citizen science survey which asks everyone to count the number of insect splats on their vehicle number plates after carrying out essential journeys as a marker of insect abundance. By repeating the survey every year, we can build a better picture of how our insect populations are faring to inform better conservation policy and practice.

Sometimes, the answers to these mysteries can be found in the most unexpected places. Recently, a novel collaboration began between Kent Wildlife Trust and Essex and Suffolk Gliding Club, bringing together two seemingly unrelated fields – wildlife conservation and aviation. The goal? To develop a unique Bugs Matter methodology for recording the number of bug splats on glider wings, offering valuable insights into insect populations soaring high above the ground. This partnership not only sheds additional light on insect abundance, but also highlights the importance of cross-disciplinary collaboration in understanding our environment, a key component underpinning Goal 2 of our Wilder Kent 2030 Strategy: Inspire and Collaborate. A few weeks ago, I joined Lawrence, Kent Wildlife Trust’s Ecological Data Analyst Lead and Bugs Matter project lead, to meet Adrian, passionate pilot of the Essex and Suffolk Gliding Club and dedicated citizen scientist.

Meeting Adrian and the science of gliding

Our journey began with a warm welcome from Adrian at the base of the gliding club. With a deep passion for gliding, Adrian delved into the science behind gliders – those sleek, motorless aircraft that ride the currents of the sky. Adrian explained the intricacies of glider design, the principles or aerodynamics, and how these aircraft can soar silently through the atmosphere, providing a birds-eye view of the world below. He told us that, during the summer, members of the gliding club regularly make cross-country flights, mostly between 2,000 and 5,000 feet altitude and typically between 100 to 300km in distance. They had noticed that, during the course of a flight, bug splats would accumulate on the leading edge of the glider wings. Glider pilots are very conscious of this as it reduces the performance of the glider by disruption the airflow over the wing. To mitigate this, pilots make a habit of cleaning the wings before every cross-country flight. As an avid citizen scientists who regularly takes part in Bugs Matter, Adrian had reached out to see if there was a way to develop a methodology to record bug splats on glider wings to provide information about insect numbers in the atmosphere high above ground level. He and his fellow pilots had observed a huge loss in the numbers of swallows and swifts in the last 15 years, and wanted to see whether if there was a reduction in insect numbers (their prey) that may be a contributing factor. 

Discussing data collection

Members of the gliding club had experimented with a marked area on the wing of their main training glider. During our visit, Lawrence and Adrian delved into how to roll this out across the gliding club. Each flight is recorded using a GPS signal which gives position and altitude information for the entire flight to accompany the bug splat data. By counting the number of insect splats on glider wings during flights, we could gain insights into insect abundance at altitudes far above ground level – a region largely unexplored when it comes to insect studies. Lawrence’s expertise in data collection and analysis provided guidance on how to ensure the accuracy and significance of the collected data to add to the invaluable citizen science data that is already being collected as part of the Bugs Matter survey.

Taking to the skies

The highlight of the day was undoubtedly the chance to experience gliding firsthand. After volunteering Lawrence to take the first flight, it was my turn to take to the skies. Strapped into the cockpit alongside Adrian (and after a quick parachute safety briefing), we were towed into the air with a winch, accelerating to around 60mph in 3-4 seconds. Our glider was then released to ride the thermals independently. The sensation of floating effortlessly and in near silence, felt both serene and exhilarating at the same time. Adrian spent time explaining what we could see below us, and even let me have a go at controlling the glider myself!

Pioneering conservation through collaboration

The Bugs Matter methodology, practiced by thousands of citizen scientists in their cars on the ground, is now taking off in more ways than one. The data collected by the Bugs Matter survey, Essex and Suffolk Gliding Club, and that of other gliding clubs should they be inspired by these efforts, has the potential to provide unique insights into our understanding of insect populations and their distribution. Insects play a crucial role in our ecosystems – pollinating plants, decomposing organic matter, forming the basis of many food chains; without them, life on Earth would collapse. The data from Bugs Matter and collaborations like these could have far-reaching implications for effective insect conservation policy and practice.

Our visit to the Essex and Suffolk Gliding Club exemplified how diverse fields can come together to unravel mysteries and drive scientific progress. We’re excited to see what the data from the gliding club shows us, and encourage any other gliding clubs to get in touch! The Bugs Matter survey is running until 31 August, so there is still time for all citizen scientists across the country to contribute crucial scientific data using their cars. Simply download the free Bugs Matter app to log the number of bugs splatted on your vehicle number plate after carrying out essential journeys. In August, we are encouraging everyone to take part in the Great British Bug Off – a special effort to remember to record all of your essential journeys before the Bugs Mater survey season ends! We have even created some free printable resources to remind you to take part.
