Walshomyia cupressi is a North American species of midge that induces galls on pygmy cypress and Sargent cypress trees in California and Oregon.[1][2][3] The larval stage lasts for almost two years before adults emerge from exit holes from the side of the gall.[2] The holotype species was collected in 1967 in Mendocino County, California and described by Raymond Gagné in 1969.[4]
