A tall goldenrod nods its head into a candy-cane curve (left) during the early weeks of growth, but will straighten up to bloom. Ducking may offer some protection from a pesty gall midge, a new study shows. The tall goldenrod (right) bears the signs of attacks by both insects tracked in the study. A midge caused the leaf rosette gall at the top of the stem, while a fruit fly induced the swelling ball gall lower in the stem.
