This dataset includes compiled information on species traits, ecological preferences and distribution metrics for 48 species of ladybird considered resident in the United Kingdom. Ecological traits including information on morphology, habitat and diet preferences, and phenology as well as information on species distributions, trends in species occupancy over time, and species temperature indices have been determined where possible for each of the 48 species. An open access data paper is available for this dataset [Outhwaite, C.L., Cocker, L., Comont, R.F., White, H.J., Powney, G.D., Turvey, K., Roy, H.E., & Brown, P.M.J. (2025).
