Some days I can’t tell if honeybees are coming or going. In a sense, they’re everywhere – collecting on our shelves, decorating our homes. In the supermarket this week I passed bee-themed mugs, place mats, bath towels and lunchboxes – not to mention the honey (I LOVE bees, the girl at the checkout told me, when I told her I was a beekeeper. She showed me her bee earrings and a bee-shaped pendant. I really love them, she said, tucking the necklace back inside her shirt collar). And yet, elsewhere, out there, where the real bees live, we’re told there are losses and declines and last month I heard a new word, insectageddon.
That came from an article about a study in Germany, among the first of its kind. Between 1989 and 2016, 1,500 insect samples were collected across 63 sites – a total haul of over 50kg, and several million flying creatures. The results are disturbing: a 76% drop in numbers, over 27 years.
Since the paper was published, more scientists have stepped forward to suggest the findings are likely to reflect a pattern occurring across Europe and beyond.
We’ve heard already about losses to honeybee, butterfly and bumblebee populations; these findings dramatically extend the scale. Around one third of our global food supply is dependent upon honeybees and other pollinating species – if flying insects were to disappear, not only would we lose individual species; our landscapes, our ecologies, our diets and so even the stuff of our own bodies, would also be radically changed.
It’s one thing to read headlines like these; another to absorb them. The words are big. They’re dramatic, they’re catastrophic. I imagine they’re probably driving the appetite for honeybee mugs and bath towels – loss can make us grabby. Yet when I look out of the window, it is not catastrophe, not ageddon, that I see.
A few years ago, when I was living in Oxford and about to become keeper to a colony of bees, this was something I’d been struggling with. I’d read about honeybee losses in the papers. It sounded bad, but it felt remote; I wondered what would happen if I stepped to one side of the newspaper headlines and got to know a colony firsthand. Would I sense a slippage, a thinning? And would I, in my slim end terrace with a weedy garden out back and a work/life balance tipping dangerously towards collapse, find a way of sustaining the bees in my care – of keeping them?
I bought a suit. I got a colony. I was suddenly more involved in another creature than I had been for years. I tended them, fretted over them. I hefted pieces of hive and beekeeping equipment. It was both a love and a labour.
My garden was bordered by a crumbling wall, a hedge and a high fence; standing inside it, I couldn’t see very far at all. I could see the sky. I could see a warehouse roof, our neighbours’ house, the tops of the trees lining the allotments. I could hear the traffic on the road outside, and the man who shouted as he walked. I wasn’t mindful of much of this; I was busy focusing on the hive. I had to become very attentive to what was happening inside it; to watch for slight shifts in the activity of the colony that might signal disease or pests or a drop in available forage. I wanted to get to know their rhythms, understand their processes (these were different, I realised, on different days – a colony is as changeable as the weather).
Up close like this, I learned a little about the landscape. A little about how bees make sense of the world, how they perceive it. And, by watching their journeys, by looking for what they were bringing back, I learned something about what they were finding out there, beyond the fence; about what their world was composed of. Honeybees collect pollen for feeding young and nectar for making honey; they temporarily ingest the nectar when they carry it back to the hive, and stick the pollen to their knees. A few months in, a friend showed me how to tell the source of these pollen nubs by their colour, and so make a fairly reasoned guess as to where the bees had flown. Deep yellow might be dogwood; soft green was probably meadowsweet. I felt like a detective, sifting for clues. Except that, for the most part, the clues were in a language I didn’t speak.
A honeybee colony is like nothing else. It froths and boils and quivers and shakes; it murmurs and thrums and whines. Lifting the lid of a hive and taking a look inside can be a disorienting experience – the bees are so foreign, so far from your familiar, they can make you feel completely lost; they can also turn you around, and inside out – they can rearrange how you see. They rearranged and reorientated me.
I’m writing this on a wooden stool, in the window of a small cafe. They have baklava and free wifi. I can look out and see a road and a row of houses; I can look out and see the silvery rim of a stand of beeches, a heap of ivy hanging over a wooden fence, two kids in jeans with mud on their knees kicking a punctured football at a wall. For the last half hour, I haven’t actually looked out of this window at all; I’ve been reading about that German study, the one that prompted calls of an insectageddon.
Today I am interested not so much in the findings, but the method. I have been learning (as the football bounced off the window of a passing car, and the car stopped, and the boys made a run for it,) about malaise traps. A malaise trap is like a tent on stilts, pitched at one end and made of netting. Inside the pitched roof there’s a funnel leading to a collecting cylinder with a quantity of ethanol inside, a killing agent. The other end of the tent is wide open; when insects fly in, they head up through the funnel and get trapped in the collecting cylinder. The basic design was invented in 1934 by René Malaise, hence the name. It was the sole means of sampling in the German study.
Over the past 27 years, between the months of March and October, malaise traps were placed in 63 nature reserves across west Germany. The cylinders were emptied and their contents weighed every few days. The work was done not by scientists but amateur entomologists, who visited and monitored the traps and made detailed recordings of the weather. They had strict instructions. The samples were weighed (with minute accuracy, since the creatures were featherlight); the weights later combined and compared. Leaving a trap open for a prolonged period can be harmful to local insect populations, so those used in the study tended to be moved from one year to the next, and for this reason the pattern that emerges reflects not the individual stories of specific sites, but something more like an accretion; a collecting up and laying out through time of umpteen temporary and scrupulously recorded views.
I wonder about those amateur entomologists who emptied the collecting cylinders, who tramped down to the tents each week. Did they have a sense, as they tipped the alcohol-soaked specimens onto the weighing scales, of the extent of the pattern unfolding? Did they sense disaster? Or was the change was too small, too slight to notice week-to-week?
Nature reserves exist with the sole purpose of preserving ecosystem functions and biodiversity, so to find such a sharp decline in resident species is alarming. The researchers studied the findings; they factored in changes to land use and the weather. Neither could account for the declines, which occurred throughout the growing season, and irrespective of habitat type. Large scale factors must be involved, they reasoned – but such factors lie beyond the scope of their investigations.
A nature reserve is a protected space but it is also a form of island, and recording only the environmental changes inside the parks will never give a complete picture because islands don’t exist in isolation. Almost every reserve included in the study was surrounded by agricultural land, which over the last half century has undergone a process of rapid intensification. Farmland has very little to offer for any wild creature, Professor Dave Goulson, one of the researchers, is quoted as saying. With the loss of field margins, increased pesticide use and year-round tillage, vast tracts of land [are now] inhospitable to most forms of life. It is possible that insects were flying beyond the perimeter of the reserves to find their foraging and nesting habitats had disappeared; or that chemicals present in the wider landscape were directly harming them.
There is an urgent need to uncover the causes of this decline, the researchers conclude. And so call upon all of us –scientists, amateur entomologists, beekeepers, supermarket cashiers, and people sitting in cafe windows – to join in the work of uncovering. To come close enough to see the detail, to pay attention to small things with the express aim of extending our range of vision, of better reading and making sense of the whole. Such a task will involve getting lost, giving up some of our go-to means of understanding the world, and drawing connections in places we hadn’t before. It will be a love and a labour. And it can start right now.
Remembrance Day for Lost Species, held on 30th November each year, is a chance to explore the stories of species, cultures, lifeways and habitats driven extinct by unjust power structures and exploitation, past and ongoing. It emphasises that these losses are rooted in violent, racist and discriminatory economic and political practices. It provides an opportunity for people to renew commitments to all that remains, and supports the development of creative and practical tools of resistance.
In light of the recent sharp declines in the populations of pollinators, on whose vital environmental contribution so many species (including humans) rely, the theme of Lost & Disappearing Pollinators is offered this year as inspiration. These are animals which move pollen from the male to the female part of a flower, thus fertilising it. Well-known pollinators include bees, butterflies and moths. Certain birds and mammals are also important pollinators, notably bats, hummingbirds and many other animals. Some pollinators, such as the small Mauritian flying fox, are already extinct at human hands, with swathes of others being critically endangered or feared lost, e.g. Franklin’s bumblebee.
Participate in Remembrance Day for Lost Species by joining – or holding – any kind of memorial to lost species or ways of life. This could take the form of an art project, a procession, lighting a candle, planting a tree, or any kind of action you like. Collaboration and inclusivity are at the heart of this initiative, so any offering is welcomed. Please share your plans with us here.
