Last year I wrote about the Insect Armageddon story – an important paper that received some exaggerated media hype.
A new paper just published in PNAS adds another twist to the insect declines saga…clearly, this story is far from over.
Lister & Garcia analysed data collected in the Luqillo Experimental Forest in Puerto Rico. This area of tropical rainforest is not a ‘pristine’ untouched wilderness, as some media reports are claiming – no place on Earth is untouched by humans! The site has been a long-term research location for decades, going back to the early 1900s, with a focus on experiments to understand the effects of disturbances of all kinds. Many important experimental research projects involving human disturbances (like this one) have happened in the Luqillo forest.
This study is important for a few reasons. Continue reading
I recently discovered this gorgeous book, loaned to me by a colleague (Elizabeth Hale, who blogs over at Antipodean Odyssey).
These days, children’s books and popular media often portray insects as scary creepy-crawlies, and the decline in outdoor play and education means many kids rarely encounter an insect that’s not a household pest.
Back in Victorian times, before screentime entertainment, things were a bit different. Victorian entomologists wrote widely on the wonders of insects, from their roles in Shakespeare’s plays to the ecosystem services they provide. Continue reading
I was recently interviewed for a great new podcast on ABC called Science Friction by Natasha Mitchell. The episode is about insect declines, including the Insect Armageddon story I blogged about last year. Natasha also talks to two well-known Australian entomologists, Ary Hoffmann and Ken Walker, as well as Caspar Hallmann one of the authors of the German insect decline study. It’s really nicely produced and explores more than just the decline issue, showcasing how wonderfully unique insects are and why we need to spend more time getting to know them!

Last week I was delighted to attend a workshop at Monash University focused on using EICAT methods to assess environmental impacts of invasive insect species. Thank you to Melodie McGeoch and her team (Dave, Chris & Rebecca), and Andrew and Carol from the Invasive Species Council, for inviting me in the first place, and for organising an excellent, productive week. We were also very lucky to have Sabrina Kumschick and Helen Roy there to share their expertise in developing and using EICAT.
It was a ‘proper’ workshop, i.e. a small group of researchers working on a project together with planned outcomes, rather than a training or upskilling ‘workshop’ (why aren’t they just called courses?!). As an early career researcher, it was so rewarding to be there. Research workshops have similar benefits to conferences, in that you have the opportunity to discuss new ideas and network outside your normal collaborative groups. But I find workshops much more fulfilling than conferences, because you have more time to develop those ideas, learn new perspectives, and really get to know people you may not otherwise cross paths with.

Production benefits from invertebrates (other than pollination and natural pest control) are often overlooked in agroecosystems. There has been much more focus on the impact of insect pests. But invertebrates provide lots of other benefits in production systems. Developing sustainable farming systems is an imperative for our future – sustainable systems are those that produce food and fibre, while also enhancing human well-being and supporting ecosystem function through ecologically-sound management. Understanding how farms can be managed to enhance production via the benefits invertebrates provide is a key to sustainable agriculture. Continue reading
When people say ‘wildlife’, they usually mean ‘animals’ (and sometimes birds). Occasionally, they might lend a fleeting thought to botanical beauties. But rarely are arthropods thought of. Aside from the charismatic honey bees and butterflies, the tiny, squidgy, creepy, crawly arthropods are easily overlooked. They can’t be cuddled and squealed over, and the most commonly-encountered ones are often scary or annoying. Google image search ‘I love wildlife’ and you mostly get big cats, bears, meerkats and baby things.
Technically, arthropods are animals too, just another Phylum in the Kingdom of Animalia, parallel with the chordates (animals, reptiles, and birds). So there is absolutely no reason not to include them in talk of ‘wildlife’. Yes, cheetahs, pygmy possums and meerkats are darned cute – I get giddy over them too! But arthropods are just as endearing. And they are also a vital link in the ecosystems that the cheetahs and meerkats frolic in every day.
Unfortunately, most of the attention that arthropods get is unfavourable or in shock. Spiders are terrifying, mosquitoes and flies are annoying, cockroaches are gross, praying mantises are just off the charts with wackiness. If we are not staring in horror and awe, we’re reaching for the spray can. Remember Danny Kaye’s soothing fairytale ode to the Inchworm? Today, inchworms are mistakenly blacklisted as pests, doomed to death before they can finish measuring the marigolds. Continue reading
