Digrammia muscariata is a of geometrid in the Geometridae. It has been recorded at blacklighting displays in California, where it is attracted to ultraviolet light sources. The species was originally described as Tephrina muscariata by Guenée in 1858. Three are recognized: D. m. muscariata, D. m. respersata, and D. m. teucaria.
