Bumblebees have become increasingly stressed by changes in climate over the past century, researchers examining museum specimens have found. Bees develop asymmetrical wings when they experience stress during development, and by examining a series of preserved specimens and their dates, the scientists found bees showed higher levels of wing asymmetry in hotter and wetter years.

Plummeting insect numbers ‘threaten collapse of nature’
The world’s insects are hurtling down the path to extinction, threatening a “catastrophic collapse of nature’s ecosystems”, according to the first global scientific review. More than 40% of insect species are declining and a third are endangered, the analysis found. The rate of extinction is eight times faster than that of mammals, birds and reptiles. […]
US plan to genetically alter crops via insects feared to be biological war plan
Government-backed researchers in America are aiming to use virus-carrying insects to genetically engineer crops – raising fears the technology could be used for biological weapons. A new article in the journal Science explores the shadowy program funded by the US Defense Advanced Research Projects Agency (Darpa). The program aims to disperse infectious, genetically modified viruses […]
How “insect soup” might change the face of conservation
Much of what we know about patterns of biodiversity has come from extensive fieldwork, with expert researchers sampling and identifying species in a process that takes thousands of man-hours. But new technologies may revolutionize this process, allowing us to monitor changes in biodiversity at speeds and scales unimaginable just a decade ago. A new paper […]
Thread-winged-Lacewing (Nemoptera bipennis)
One of the most beautiful Iberian insects is the Wood Fairy or Thread-winged-Lacewing (Nemoptera bipennis), known as Duende in Spanish which translates as an elf or a fairy. My two younger daughters and I went out to look for them in one of the smaller pine woods on the edge of Barbate Marismas. Within a […]
Bumblebees take off with a special fungus weapon to save strawberries
Squadrons of bumblebees are being deployed in a novel attempt to prevent grey mould turning the summer’s strawberries into fluffy mush. The bees are routed via a one-way system in their hive through a tray of harmless fungus spores which, when delivered to flowers, ensure that the grey mould cannot take hold as the fruit […]
UK’s rare spring butterflies make a late show
The UK’s spring butterflies are being welcomed by enthusiasts, but weeks later than they usually arrive. The second-coldest March on record contributed to the delayed emergence of many rare species, according to the charity Butterfly Conservation. “First sightings” recorded by the public showed the insects typically appeared a fortnight later than normal. One rare species […]
Canon’s Best Macro Lens for Nature Photography: Canon EF 180mm f/3.5L
It may surprise you that I believe Canon’s 180mm macro lens to be the best macro lens for nature photography. After all, a few years ago, Canon released a new macro lens, the EF 100mm f/2.8L. It’s smaller, lighter, cheaper, auto-focuses faster, has a wider maximum aperture, and it even sports a new hybrid form […]
