This data was collected as a part of the MULTICLIM project (https://www.mn.uio.no/ibv/english/research/sections/aqua/research-projects/144612/). In this study, we determined the sublethal effects of short-term imidacloprid exposure and post-exposure recovery in the collembolan Folsomia quadrioculata, which occurs abundantly across the northern hemisphere. Imidacloprid is a globally-used neonicotinoid insecticide, which can persist in the soil long enough to elicit adverse responses in non-target organisms. We assessed survival, egg production, and hatching success in adult springtails exposed for 14 d through the diet to imidacloprid followed by a 28 d post-exposure phase. Our findings suggest that low imidacloprid exposures can restrict reproduction, with potentially severe consequences for the population, notwithstanding the partial recovery in egg production
