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]
