“Insectageddon” – bigger headlines, more hype, but where’s the funding?

Unless you have been hibernating in a deep, dark cave or on another planet, you can hardly have missed the ‘insectageddon’ media frenzy that hit the UK (and elsewhere) on Monday (11th February).

This time the stimulus was a review paper outlining the dramatic decline in insect numbers, from two Australian authors (Sánchez-Bayo & Wyckhus, 2019).  Their paper, based on 73 published studies on insect decline showed that globally, 41% of insect species are in decline, which is more than twice that reported for vertebrates.  They also highlighted that a third of all insect species in the countries studied are threatened with extinction.  Almost identical figures were reported some five years ago (Dirzo et al., 2014), but somehow escaped the attention of the media.

I’m guessing that a clever press release by either the authors’ university or from the publisher of Biological Conservation set the ball rolling and the appearance of the story in The Guardian newspaper on Monday morning got the rest of the media in on the act.

The headline that lit the fuse – The Guardian February 11th  2019

The inside pages

A flurry of urgent phone calls and emails from newspapers, radio stations and TV companies resulted as the various news outlets tried to track down and convince entomologists to put their heads above the parapet and comment on the story and its implications for mankind.  I was hunted down mid-morning by the BBC, and despite not being in London and recovering from a bad cold, was persuaded to appear live via a Skype call.  A most disconcerting experience as although I was visible to the audience and interviewer, I was facing a blank screen, so no visual cues to respond to.  According to those who saw it, it was not a disaster 🙂  Entomologists from all over the country, including at least three of my former students, were lured into TV and radio studios and put through their entomological paces.

Me, former student Tom Oliver (University of Reading), Blanca Huertas (NHM) and former student Andy Salisbury (RHS Wisley), getting our less than fifteen minutes of fame 🙂

As far as I know, we all survived relatively unscathed and the importance of insects (and entomologists) for world survival was firmly established; well for a few minutes anyway 🙂

It is the ephemeral nature of the media buzz that I want to discuss first.  Looking at the day’s events you would be forgiven that the idea of an ecological Armageddon brought about by the demise of the world’s insects was something totally new.   If only that were so.

Three years of insect decline in the media

The three years before the current outbreak of media hype have all seen similar stories provoking similar reactions, a brief flurry of media attention and expressions of concern from some members of the public and conservation bodies and then a deafening silence. Most worrying of all, there has been no apparent reaction from the funding bodies or the government, in marked contrast to the furore caused, by what was, on a global scale, a relatively minor event, Ash Die Back.  Like now, I responded to each outcry by writing a blog post, so one in 2016, one in 2017 and another last year.

So, will things be different this time, will we see governments around the world, after all this is a global problem, setting up urgent expert task forces and siphoning research funding into entomology? Will we see universities advertising lots of entomologically focused PhD positions?  I am not hopeful. Despite three years of insectageddon stories, the majority of ecology and conservation-based PhDs advertised by British universities this autumn, were concerned with vertebrates, many based in exotic locations, continuing the pattern noted many years ago. In terms of conservation and ecology it seems that funding is not needs driven but heavily influenced by glamorous fur and feathers coupled with exotic field sites (Clarke & May, 2002).

The paper that caused the current media outbreak (Sánchez-Bayo & Wyckhus, 2019) although hailed by the media as new research, was actually a review of 73 papers published over the last several years.  It is not perfect, for one thing the search terms used to find the papers used in the review included the term decline, which means that any papers that did not show evidence of a decline over the last forty years were not included e.g. Shortall et al. (2009; Ewald et al. (2015), both of  which showed that in some insects and locations, populations were not declining, especially if the habitats that they favoured were increasing, e.g. forests, a point I raised in my 2018 post.  Another point of criticism is that the geographic range of the studies was rather limited, almost entirely confined to the northern hemisphere (Figure 1). Some commentators have also criticised the analysis, pointing out that it was

Figure 1. Countries from which data were sourced (Sánchez-Bayo & Wyckhus, 2019).

not, as stated by the authors, a true meta-analysis but an Analysis of Variance.  Limitations there may be, but the take home message that should not be ignored, is that there are many insect species, especially those associated with fresh water, that are in steep decline.  The 2017 paper showing a 75% reduction in the biomass of flying insects in Germany (Hallmann et al., 2017), also attracted some criticism, mainly because although the data covered forty years, not all the same sites were sampled every year.  I reiterate, despite the shortcomings of both these papers, there are lots of studies that show large declines in insect abundance and they should not be taken lightly, or as some are doing on Twitter, dismissing them as hysterical outpourings with little basis in fact.


It is extremely difficult, especially with the lack of funding available to entomologists to get more robust data.  The Twitter thread below from Alex Wild, explains the problems facing entomologists much more clearly and lucidly than I could.  Please read it carefully.

Masterly thread by Alex Wild – millions of insects, millions of ways to make a living and far too few entomologists

I am confident that I speak for most entomologists, when I say how frustrated we feel about the way ecological funding is directed.  Entomologists do get funding, but a lot of it is directed at crop protection. Don’t get me wrong, this is a good thing, and something I have benefited from throughout my career.  Modern crop protection aims to reduce pesticide use by ecological means, but we desperately need to train more entomologist of all hues and to persuade governments and grant bodies to fund entomological research across the board, not just bees, butterflies and dragonflies, but also the small, the overlooked and the non-charismatic ones  (Leather & Quicke, 2010).  A positive response by governments across the world is urgently needed.  Unfortunately what causes a government to take action is hard to understand as shown by how swiftly the UK government responded to the globally trivial impact of Ash Die Back but continues to ignore the call for a greater understanding of the significance of and importance of insects, insectageddon notwithstanding.

I put the blame for lack of entomological funding in the UK on the way that universities have been assessed in the UK over the last twenty years or so (Leather, 2013). The Research Excellence Framework and the way university senior management responded to it has had a significant negative effect on the recruitment of entomologists to academic posts and this has of course meant that entomological teaching and awareness of the importance of  insects to global health has decreased correspondingly.

I very much hope that this current outbreak of media hype will go some way to curing the acute case of entomyopia that most non-entomologists suffer from. I  fear however, that unless the way we teach biology in primary and secondary schools changes, people will continue to focus on the largely irrelevant charismatic mega-fauna and not the “little things that run the world”

Perhaps if publicly supported conservation organisations such as the World Wide Fund for Nature concentrated on invertebrates a bit more that would help.  A good start would be to remove the panda, an animal that many of us consider ecologically irrelevant from their logo, and replace it with an insect. Unlikely I know, but if they must have a mammal as their flagship species, how about sloths, at least they have some ‘endemic’ insect species associated with them 🙂

Entomyopia and Entoalexia – two potentially life-threatening conditions

This post was stimulated by two recent events.  First, a conversation I had at a curry evening organised by the amateur band that my wife plays in.  My neighbour was a well-educated modern languages teacher in her early forties.  We discussed our various jobs and she evinced surprise that anyone would want to work with insects and even when I explained the myriad benefits of understanding insect biology and ecology to her in terms of food security, vector control, detritivores, integrated pest management, pollination etc., she was still unconcerned about the lack of training provision for entomology and the dwindling number of young entomologists in the population.  I also highlighted the growing disconnect between people and nature.  Her response was that it was just the way it was and that people had other interests now!  I was, despite the fact that I have bemoaned the lack of funding for invertebrate research and training for some time now, totally amazed and down-hearted.  The second event was when one of my entomological colleagues reported to me how shocked he had been, when describing the recent opening of our new entomology building at Harper Adams University to his next door neighbour, a retired engineer, that the neighbour expressed great surprise that anyone would want such a facility and why anyone would want to spend that amount of money to enable entomological research.

I have written before about my worries about the decline of interest in natural history and entomology (Leather & Quicke, 2009, 2010) but I feel that it is now well past time to do something urgently about this lack of understanding among the public, the educational establishment, funding councils and the government.  Not only is institutional invertebratism  (Leather, 2009, 2013) still alive and well but we now have two potentially life-threatening conditions that desperately need curing.



entomological short-sightedness

        • a condition in which insects are viewed either as pollinators or as nuisances
        • a lack of foresight or discernment as to the importance of entomology:  a narrow view of entomology



entomological blindness

        • a condition in which a person or organisation, is totally oblivious to the importance of entomology and insects

Insects - what insects


The closing of entomology departments and research groups

A reduction in the numbers of entomologists employed by universities and research institutions

An ageing population of practicing entomologists, many characterised by grey beards and spectacles

Lack of understanding by the general public about why the study of entomology is important to their well-being

A lack of teaching of invertebrate biology at secondary schools and at undergraduate level

A lack of government funding

A tendency for members of the general public to scream and/or flinch when insects enter their personal space

A tendency for members of the general public to kill insects when found in their personal space

A failure by the majority of the population to appreciate the beauty and wonder of insects

Investing hundreds of millions into medical research to keep people alive for longer (a good thing) without thinking about how the extra mouths are going to be fed without similar levels of investment in crop protection research (a very bad thing)

Funding in conservation and whole organism biology and ecology heavily biased towards “large charismatic mega-fauna”

Schoolchildren able to name the ten most endangered mammal species in the world but unable to recognize and name the ten most common insect species in their own country



A concerted effort by all entomologists to explain to the general public, the educational establishment, funding bodies, the media and  government why we need urgently more entomologists and why the study of entomology is crucially important to our well-being.  I would go further than that and suggest that we need to redouble our outreach activities and to actively lobby those who hold the purse strings and those that represent us in government.  Yes, national entomological societies such as the Royal Entomological Society in the UK are doing much more to promote entomology than they used to but much more remains to be done.  The Amateur Entomologist’s Society  has, I have been reminded, also been active in this area for more than eighty years.  My message to all entomologists is act now before it is too late.



At the current level of investment  into treatment and cures, very gloomy.

As I was preparing this article Brigit Strawbridge published an impassioned plea to all of us to take more notice of the little things that run the world

I would be remiss if I did not point out that mycology, plant pathology and plant nematology are also extremely vulnerable and just as important to our well-being as entomology.

Entomyopia  is apparently not a new disease, shortly after posting this I came across this gem from 1882.

“No science is so generally slighted, ignored, and misunderstood as is Entomology.  Hysterical humanitarians, novelists, poets, political agitators, classical students, speak in terms of contempt or horror of the “fly-hunters””
