Li abundances vs. T_eff for the microlensed dwarf sample. Triangles represent those stars for which we could only determine upper limits on the abundances. The grey circles and triangles in the background represent the 714 stars from Bensby et al. (2014) for which Li abundances are determined in Bensby & Lind (2018) in the exact same way as for the microlensed bulge dwarfs. The sizes of the markers are scaled with the estimated ages, and the bulge stars are also colour coded based on their surface gravities according to the colour bar on the right-hand side.
