Information on the distribution, recognition and biology of Merodon analis Meigen, 1822 in France is reviewed, in the light of 2020 advances in knowledge of the Merodon constans group in Europe. Merodon analis is known to develop as a larva in bulbs of the indigenous snowdrop, Gallanthus nivalis L., 1753. An investigation carried out in Doubs (25), during the first quarter of 2021, demonstrates that Leucojum vernum L., 1753 is an alternative larval host plant, explaining the presence of Merodon analis in eastern parts of France where Gallanthus nivalis is virtually absent. Examination of the terminalia of males reared during course of this study repeatedly raised questions concerning the presence of Merodon constans (Rossi, 1794) in France, a species reported in Europe from Greece to Italy but not west of the Alps, and currently indistinguishable genetically from M. analis.
