Overview

• A peer-reviewed Nature Communications analysis of 1990–2020 records covered 1,252 species across major insect groups using machine-learning models.
• The study assessed distributional occupancy across sites rather than abundance, clarifying how national stability can mask local upheaval.
• Researchers documented pronounced turnover in community composition at local scales across Great Britain.
• Urban expansion and farmland simplification were associated with losses for habitat specialists, while rising temperatures favored species with multiple breeding cycles per year.
• Lead author Yoann Bourhis warned that these reorganizations could affect pollination, natural pest control and wider biodiversity.
