This magic number was stated in that flawed entomofauna paper, without any explanation of how this number was calculated – see why that paper is flawed here.
Since then, it has been stated regularly in popular media, scientific papers and technical reports, often without citation, just a number pulled out of the air and presented as fact.
Globally, there are about 5 million estimated insect species in total. Only 1 million species have scientific names. So, conservatively, the 40% claim suggests that at least 400,000 species are threatened with extinction.
So is it an accurate prediction? No. Here’s why: Continue reading
Our insect apocalypse paper is finally published online at BioScience, with awesome co-authors Jasmine Janes and James O’Hanlon!
We summarise the major flaws in the pop culture ‘insect apocalypse’ narrative and argue that focusing on a hyped global apocalypse narrative distracts us from the more important insect conservation issues that we can tackle right now. Promoting this narrative as fact also sends the wrong message about how science works, and could have huge impacts on public understanding of science.
And, frankly, it’s just depressing. Right now, we all need hope, optimism and reasons to act, not a reason to give up.
This blog isn’t about the paper, you can read it yourself (journal, preprint, or email me for a copy). This is about why we wrote the paper. Continue reading
When I grew up, I was taught that politics and religion were taboo subjects in social situations, sometimes even among close family. I liked to believe this social code came from a well-meaning place…the idea that we shouldn’t judge people on their personal beliefs. But I suspect it was more of a survival mechanism, evolved over generations of bloody wars that started because of political gripes and religious persecution.
As a scientist on social media I’ve often been told that I should only comment on things I have expertise in, things I actually work on. And I shouldn’t ‘get political’.
Sure, I don’t publicly comment on scientific disciplines I have no experience in. Even within ecology, I rarely comment on animals or systems I don’t work with regularly. And fair enough too. I get really frustrated when scientists without insect expertise make inaccurate public comments about insects, or when ecologists who don’t work on ecosystem services science publicly claim the concept is flawed.

I’ve seen and heard a few claims circulating that removing meat from your diet is essential to ‘save the bees’. This is misleading and draws a long bow between lots of random correlations to promote a particular agenda.
Sure, intensive meat production contributes to some big environmental problems and there are plenty of reasons to reduce your meat consumption. But there is absolutely no scientific evidence to support claims that eating meat is bad for bees.
Meat comes in many forms. From wild game to highly-processed ‘meat products’, from large-scale intensive feedlots to diversified low-intensity grazing systems, from locally-produced to high food miles. It is generally impossible to make blanket statements about all meat. Continue reading
(This is the accepted version of my review published here in Trends in Ecology & Evolution.)
It is an unfortunate paradox that insects, the most abundant and diverse class of animals on Earth, are also the most understudied and misunderstood. With diversity comes complexity, and scientists have only scratched the surface on knowledge of global insect ecology. In The Last Butterflies, ecologist and butterfly expert Nick Haddad explores some of this complexity.
Despite the title, this is not a story of despair. Nor is it just about butterflies. Haddad weaves an absorbing narrative about the multidimensional process of science and insect conservation, the damaging impacts humans can have on the web of life, the ethical quandaries of conservation, and the positive changes and solutions that give us hope. Each main chapter is focused on a single butterfly species: six of the rarest North American butterflies that Haddad has spent his career studying, and two more well-known species from North America and the UK. The eight butterflies are framing devices, each one illustrating pieces of the challenging puzzle that is insect ecology and conservation. Continue reading
Cheers to everyone who has read and shared my blog posts over the years. I’ve had some great discussions here and made some really worthwhile connections because of this little blog. Most importantly, it’s kept me inspired and connected through the highs and lows of academia. Here’s to many more blog posts, discussions, and connections to come!
I’m so happy that my current second most visited post is ‘On the importance of observations to Ecology’, an ode to natural history notes and a reminder that ecological science will stagnate without observing natural interactions occurring around us. It sums up many of the reasons why I started blogging in the first place. (It was pipped to the post by one of my insectageddon articles)
Some more on why I love blogging:

Our paper on why ecology blogs are so valuable to the academic community: Bringing ecology blogging into the scientific fold: measuring reach and impact of science community blogs. For anyone who still needs convincing that academic blogs are not a waste of time, this paper is an excellent piece of evidence: co-authors are from Don’t Forget the Roundabouts, Scientist Sees Squirrel, Dynamic Ecology, Jeff Ollerton’s Biodiversity Blog, and Small Pond Science

The ‘tyranny of the sound bite’ has plagued politicians and celebrities for decades. Pithy one-liners, taken out of context, can be extremely damaging to a person’s reputation.
In science communication, Sexy Science soundbites, condensing complex ecological problems into simple data points or the efforts of single researchers, can damage public understanding of science.
We’ve seen this with Insect Armageddon and the recent ‘3 billion lost birds’ story. Ecology is the science of nuances, and any claim of global patterns or precise data points must be interpreted with context.
Much of the problem with these soundbite disasters lies with the science communication around the story, not necessarily the science itself. Continue reading
