Beetles are insects of the order Coleoptera, characterized primarily by forewings modified into hardened elytra that cover and protect the membranous hindwings and dorsal abdomen. They exhibit complete metamorphosis with distinct egg, larval, pupal, and adult stages, and display extreme morphological, ecological, and trophic diversity, occupying roles as herbivores, predators, detritivores, and fungivores in virtually all terrestrial and many freshwater ecosystems. Coleoptera possess chewing mouthparts, a sclerotized exoskeleton, and typically well-developed antennae with taxonomically informative segmentation. With more described species than any other animal order, beetles are a major focus in systematics, evolutionary biology, ecology, and biodiversity research.
In 2025, Konstanz scientists looked very closely at rotting fruit in local orchards, and observed what no one had before—worms, hundreds of them, twisting skyward into self-assembled living structures known as "towers." It ...

Rove beetles have evolved a neat trick to survive. They cloak themselves in ant pheromones, allowing them to enter and remain undetected within ant colonies. But it comes with a catch. Once a rove beetle lineage evolves this ...
As Europe seeks to curb its dependence on China for rare earths, plans to mine the continent's biggest deposit have hit a roadblock over fears that mining operations could harm endangered beetles, mosses and mushrooms.
