Abstract The Anthropocene is characterised by pervasive human‐inflicted impacts on a broad range of biota, including insects. In 2019, we reviewed scientific literature quantifying the prevalence and magnitude insect declines in recent time. Here, drawing upon 40 additional long‐term studies, add evidence that consistent with our earlier review some other reviews fate populations globally. New data for Greenland, northern Africa, South America, eastern Asia Australia complement studies from Europe North America. Temporal trends are now derived 100 refer mainly to past three or four decades (median 33 years). Data 10 major taxonomic orders indicate an average 37% species declining numbers, while 18% increasing; latter taxa involve agricultural herbivores nuisance pests. Population changes more pronounced among aquatic communities, where 42% 29% increasing. Such result decrease biomass across taxa, except Heteroptera. Changes richness diversity indices inconsistent do not reflect intraspecific population over These observed irrespective taxon, geography methodological approach, although lack monitoring records prevents proper assessment tropical regions.
