Bogong moths: pest, icon, or just another insect species we know very little about?

The Bogong moth story is a fascinating example of how complex insect life cycles don’t translate well to simplified sound bites.

Recent observations that there are fewer Bogong moths (Noctuidae: Agrotis infusa) in the Alps this summer made the news. One of the researchers credited with the observations found no moths in three caves he had visited last year, but he did find some in other caves in the region. There are limited long-term data on Bogong moth populations, and all of this news appears to be based on anecdotes, so it is impossible to verify if the species is truly in decline. Continue reading

Insectageddon is a great story. But what are the facts?

Hype is an ineffective communication strategy, especially when based on limited facts. There are many elements to effective communication – simply raising awareness about a problem is not enough if audiences don’t engage with the facts and participate in developing solutions.

The latest instalment in the Insect Armageddon saga is out. I wasn’t going to write about it. After my previous posts, I didn’t want to sound like a stuck record. But I’ve had a few media requests, some from journalists who found my original blogs. Most journalists I spoke to have been great, and really understand the importance of getting the facts straight. But a few seemed confused when they realised I wasn’t agreeing with the apocalyptic narrative – ‘other scientists are confirming this, so why aren’t you?’

This latest review paper has limitations, just like the German and Puerto Rican studies that received similar hype over the last few years. This doesn’t make any of them ‘bad’ studies, because every single research paper has limitations. No single study can answer everything neatly. Science takes time. Continue reading

A community of solitary hymenopterans

You don’t need to plan expensive field expeditions to find exciting natural history observations.

Last weekend, my husband dragged me away from grant-writing for a quick afternoon outing. We headed to Dangars Gorge, about 20 minutes’ drive from Armidale. The gorge is part of the World Heritage Gondwana Rainforests, a protected area we are so lucky to have on our doorstep. Sadly, it’s a bit dry this year.

Every time we’ve visited, I’ve hit the ecology observation jackpot: an interesting interaction, a new species record, or a natural history mystery. So I had my camera on hand, just in case. And I didn’t have to look far… Continue reading

Australia’s threatened insects

A couple of weeks ago I gave a talk at the Insect Ecology Research Chapter workshop at the Ecological Society of Australia’s annual conference in Brisbane. I talked about how policy and popular media influence insect conservation in Australia; as an example, I discussed this research by Toby Smith and me showing how introduced honey bees dominate mainstream media coverage of pollinators in Australia.

I also collated data on which insect species are officially listed as threatened species in Australia. In Australia, we have a national list (under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999) of flora and fauna species that are considered threatened at a national scale. In addition, each individual state and territory has its own threatened species list under various state legislation. Continue reading

Insect declines: pay attention

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

Nature’s sugar shack

Following on with the theme from my last post, here’s an article I wrote for the latest issue of the wonderful Wildlife Australia magazine.

Scale insects get a hard time. We usually think of them as pests, based on our experience with them in gardens and farms. But if a scale insect is living on a tree in the middle of a forest far from any human community, is it a pest? Or part of a complex web of interactions? Every living thing contributes to ecosystem function somehow and there are lots of interesting interactions that we overlook by focusing on simplistic labels.

Honey by any other name…

Did you know that honey bees aren’t the only insect that can make honey?

Read my article at The Conversation:

Wasps, aphids and ants: the other honey makers

There are seven species of Apis honey bee in the world, all of them native to Asia, Europe and Africa. Apis mellifera, the western honey bee, is the species recognised globally as “the honey bee”. But it’s not the only insect that makes honey…..
