Abstract
Ceratovacuna cerbera n. sp., a woolly aphid producing pseudoscorpion-like 1st-instar soldiers in its colonies on Sasa spp., is described from Japan and Korea. We found that both the soldiers and "normal" 1st-instar nymphs attacked artificially introduced insect larvae. Three alates were collected in Japan in November. Because they were secondary migrants and not sexuparae, the life cycle is probably anholocyclic in Japan.
