Birds, fish and caribou are all known for their long migrations, but did you know insects migrate too?
According to a new study, each year 17.1 million insects move through a 98.4-foot gap in the Pass of Bujaruelo between two Pyrenees peaks on the border between Spain and France.
For four years, a team of scientists from the University of Exeter visited the pass to monitor the extensive number of species of day-flying insects on their way south.
“In autumn 1950 David and Elizabeth Lack chanced upon a huge migration of insects and birds flying through the Pyrenean Pass of Bujaruelo, from France into Spain, later describing the spectacle as combining both grandeur and novelty. The intervening years have seen many changes to land use and climate, posing the question as to the current status of this migratory phenomenon,” the authors wrote in the study. “Numbers at this single site hint at the likely billions of insects crossing the entire Pyrenean mountain range each year, and we highlight the importance of this route for seasonal insect migrants.”
The insects migrating along this well-established route start their journeys in the United Kingdom and other parts of northern Europe.
“[Elizabeth and David Lack] witnessed remarkable numbers of marmalade hoverflies migrating through the mountains, the first recorded instance of fly migration in Europe. In 2018, we went to the same pass to see if this migration still occurred, and to record the numbers, species, weather conditions and ecological roles and impacts of the migrants,” said Will Hawkes, lead author of the study and a postdoctoral researcher with the University of Exeter’s Centre for Ecology and Conservation, in a press release from the University of Exeter.
17 MILLION insects migrate through a 30m Pyrenean mountain pass every autumn!
They fly through the mountains on their remarkable journeys from northern Europe (including the UK) into Spain and beyond for the winter!

The researchers did counts of the small insects using a video camera and used visual counts for butterflies. To identify migrating species, they used a flight intercept trap.
“What we found was truly remarkable,” Hawkes noted. “Not only were vast numbers of marmalade hoverflies still migrating through the pass, but far more besides. These insects would have begun their journeys further north in Europe and continued south into Spain and perhaps beyond for the winter. There were some days when the number of flies was well over 3,000 individuals per metre, per minute.”
The study, “The most remarkable migrants — systematic analysis of the Western European insect flyway at a Pyrenean mountain pass,” was published in the journal Proceedings of the Royal Society B.
“To see so many insects all moving purposefully in the same direction at the same time is truly one of the great wonders of nature,” said Dr. Karl Wotton, team leader and co-author of the study, in the press release.
Insect numbers peaked during sunny, dry and warm conditions when wind speed was low and there was a headwind. This kept the insects flying low over the pass, making them easier to count.
“The combination of high-altitude mountains and wind patterns render what is normally an invisible high-altitude migration into this incredibly rare spectacle observable at ground level,” Wotton explained.
Most of the total number of insects — 90 percent — were flies, though a range of species was observed. While dragonflies and butterflies are well-known migratory species, they accounted for less than two percent. Many of the migrating insects were known garden dwellers like house flies, tiny grass flies and the cabbage white butterfly.
“It was magical. I would sweep my net through seemingly empty air and it would be full of the tiniest of flies, all journeying on this unbelievably huge migration,” Hawkes observed.
Almost 90 percent of the migrators were pollinators who carry genetic material long distances by migrating between plant populations, which improves plant health. They also transport nitrogen, phosphorus and other nutrients and assist with decomposition.
Many of the insects were “pest controllers,” such as pied and marmalade hoverflies who feed on larval aphids.
These important migrating insects are believed to be declining due to habitat loss and climate change.
“By spreading the knowledge of these remarkable migrants, we can spread interest and determination to protect their habitats,” Hawkes said. “Insects are resilient and can bounce back quickly. Together, we can protect these most remarkable migrants of all.”

Classic Sustainability In Your Ear: The Ocean River Institute’s Natural Lawn Challenge for Climate Action
Turn back the clock with this classic interview that will get you ready for Spring yard care planning. A lawn may be beautiful but it can take a heavy toll on the environment, accounting for between 30% and 60% of residential water use in the United States. Rob Moir, Ph.D., is president and executive director of the Ocean River Institute in Cambridge, Massachusetts. ORI works with residential lawn owners to heal damaged ecosystems by restoring coastal areas to lessen the destructive impacts of climate change. The benefits of a natural lawn reach far beyond reduced local water pollution, eliminating chemicals that can contribute to cancers, diabetes, Alzheimer’s disease, and other cellular diseases. Natural lawns are also better for local pollinators and store much more carbon than heavily fertilized lawns. If you considered removing your lawn to play a part in the battle against climate change, this interview may change your mind — a healthy lawn is a powerful carbon sink.
The Ocean River Institute is recruiting Massachusetts communities, town by town, to take a pledge to follow natural lawn practices in the Healthy Soils for Climate Restoration Challenge. You don’t need to live in Massachusetts to participate and learn about the alternatives to the traditional, chemical-intensive lawn practices that use Roundup, a source of glyphosates that kills soil-dwelling fungi and local pollinators, and fast-acting nitrogen fertilizers. You can learn more about the Ocean River Institute at www.oceanriver.org.
Rob has contributed many articles about climate change and the history of environmental change since this interview, including:
