On Q stellata. Also on Q breviloba, durandii [sinuata]. Cell 2.1 by 1 mm just under the bark in wood of current year's growth. Adults were cut out Apr 11, all females, and the writer is unable to separate them from Callirhytis crypta. If they are that species it is the first case of a red oak species being reared from a gall on a white oak.
