Burnettweldia conalis, formerly Disholcaspis conalis, the witches' hat gall wasp, is a species of hymenopteran that induces stem galls on Oregon oaks in North America.[1] The conical stem galls look like witches' hats lined up on a stick.[1] The base of the detachable gall appears to grip the stem.[1] Typical galls are 10 to 18 millimeters tall.[2] Young galls are green, aging galls are fuzzy, and old galls are beige.[2] The type species was collected in Sequoia National Park.[2]
