Abstract: In this paper, we describe some arithmetic properties of Lamé operators with finite dihedral projective monodromy. We take advantage of the deep link with Grothendieck's theory of dessins d'enfants, following [10, 11]. We focus more particularly on the case of projective monodromy of order 2p, where p is an odd prime number.
