Raptorial insect forelegs evolved repeatedly but never converged on one winning design
The evolutionary paths that created snatching forelimbs in insects multiple times moved in a similar direction but didn't end at a single solution. Kobe University research is pioneering a study of how organs with similar functions evolve, providing a new analytical approach to i

New beetle genus named after One Piece's Monkey D. Luffy, encompassing two new species
A research team from the Natural History Museum of Denmark has published a compelling new study in insect taxonomy in the open-access journal ZooKeys, officially establishing a new genus of rove beetle: Luffy gen. nov. The inspiration for the name comes directly from Monkey D. Lu
Parasites deliver long-chain omega-3 fatty acids to aquatic systems, feeding endangered fi
Wormlike parasites cause crickets to jump into streams, where the fatty insects nourish endangered fish. Ayano Medo and Takuya Sato sought to characterize the flow of eicosapentaenoic acid (EPA)—a nutritious long-chain omega-3 fatty acid—through aquatic and terrestrial ecosystems

Scientists warn invasive Asian mantises are threatening Europe's wildlife
Two striking Asian praying mantis species that have rapidly spread across Europe have now been officially classified as invasive, raising new concerns about their impact on native wildlife. Boosted by climate change and urban environments, these fast-breeding predators are expand
Heavy traffic can turn flower-rich verges into bumblebee traps, study finds
Heavy traffic can turn flower-rich verges into bumblebee traps, study finds
Flower-rich road verges may attract hungry bumblebees, but at the same time, they can be dangerous for the buzzing insects—if traffic is too heavy. The new research from Lund University in Sweden examined the role roadsides play for bumblebees. The results show that road verges c

Allendale, Northumberland: Farmers use it as cover crop, and I sow it into bare soil – but not before I’ve had a close look at its stunning detailsCupped by bristly sepals, the five-petalled flowers of phacelia flare open at the tips, drawing insects to their abundant nectar and
Evolutionary history shapes plant carbon storage strategies worldwide
Evolutionary history shapes plant carbon storage strategies worldwide
Two types of carbohydrates are important to plants—structural carbohydrates (which form cell walls) and nonstructural carbohydrates (NSCs). The latter group represents plants' stored energy reserves, which can be used to survive cold or drought; regrow after damage; recover from
