Abstract
Defensive behavior of the aphid Epipemphigus niisimae was observed. Gall-living nymphs of any instar attacked artificially introduced insect larvae, but the main defenders were 1st-instar nymphs, as expected from their morphology. Some non-1st-instar nymphs showed back-scratching behavior in the gall. Through a transfer experiment, Impatiens nolitangere was found to be a secondary host of E. niisimae.
