Notes gall on primary host plant ( Picea engelmannii) formed by young female nymphs which hatched from eggs laid on lateral twigs then migrated to feed at base of new terminal needle growth. This feeding causes abnormal plant cell development which results in a gall forming which then surrounds them. ID confirmed by Michael Murray and Dr Lorraine Maclauchlan FLNR Govt BC
