Insect pollinators like bees, hoverflies, and moths are vital to ecosystems but face growing threats from urbanisation. Emilie Ellis, from the University of Helsinki, tells us more about a new study across three cities that found that pollinator species richness declined by up to 43% in more urbanised areas. Moths and hoverflies were particularly vulnerable due to their complex life cycles and sensitivity to habitat loss and light pollution.

We speak to Ruby Stephens, runner-up of the 2024 Biology Letters Early Career Researcher Competition for the research paper Zygomorphic flowers last longer: the evolution of floral symmetry and floral longevity.     ◀   ◀
