Coleophora nepetellae is a moth of the Coleophoridae family. It is found in Italy (Piemont Region) and France, where it has been recorded from the Alpes-Maritimes, Upper Var, Alpes-de-Haute-Provence, Hautes-Alpes, Isère, the Drôme, and further to the west from the Vaucluse where it is common on the slopes of Mont Ventoux wherever Nepeta nepetella grows. The larvae initially feed on Nepeta nepetella. This is the food plant from which the larva makes its first case. The second host plant which serves to construct the final case is a unidentified Poaceae.
