Data from all over the globe suggest that bees are in decline, and we may lose a lot more than honey if bees are unable to cope with the changing climate and increasing demand for agricultural land.
Bats have adapted new hunting techniques in their pursuit of moths who in turn have developed defensive strategies. Sarun T/Shutterstock

Explainer: the evolutionary arms race between bats and moths

Bats have developed special attack mechanisms for hunting moths, and moths have responded by developing defence mechanisms to avoid being eaten.

Scary king cricket is a beautiful example of evolution at its best

To avoid mantids, stinkbugs evolved to hide in plain sight

Did you know that the sky isn’t actually blue? Perhaps in school you learned about how air scatters light, filtering out red light from the sun, but that is only half the story. While our eyes perceive…

In defence of the stink bug

Insects are the great survivors in evolution: new study

The time and date of the origin of insects and their pattern of evolution and survival over millions of years is revealed in a new study, published today in Science magazine. Insect relationships have…
Where the rainforest meets the plantation: there are probably a lot more insects. Ryan Woo for Center for International Forestry Research (CIFOR)

Palm oil plantations are bad for wildlife great and small: study

Palm oil plantations have an overall negative impact on biodiversity, according to research released this week. The study, published in Nature Communications, found palm oil plantations are home to fewer…

French beetles flown in to clean up Australia’s cattle dung

Good news, entomologists! Tiny insects, such as this Australian weevil, can be scanned and viewed in full colour and 3D from anywhere in the world. John Tann/Flickr

A big tick for entomologists: new 3D colour scans of insects

Observation is a cornerstone of science – we learn much about the universe and how it works just by looking at it. But observation can be a huge challenge. It’s easy to forget that human eyes allow us…

Smells like queen spirit: royal pheromones in insect colonies

Much like people, insect colonies like to know if her majesty is at home. In the ants, bees, wasps and termites (the “big four” of the social insect world), the queen has long been suspected of using special…
The Holy Grail of myrmecology: the Dinosaur Ant. Ajay Narendra

Australian endangered species: Dinosaur Ant

The Dinosaur Ant (Nothomyrmecia macrops) is so-called because it is a “living fossil”. It is arguably one of the closest living examples of what some of the earliest true ants might have been like, both…
Vesk’s Plant-louse lives only on a single species of wattle. Melinda Moir

Australian endangered species: Vesk’s Plant-louse

Vesk’s Plant-louse (Acizzia veski) was discovered in 2007 within the Stirling Range National Park, a biodiversity hotspot of southwestern Australia. It is not a true “louse” but is a species of Hemiptera…
