Abstract

Sexuparae of the heteroecious aphid Ceratovacuna nekoashi (Hormaphidinae, Cerataphidini) deposit sexuales on leaves of Styrax japonica. It was found that these 1st instar sexuales move to branches soon after birth without molting. Many sexuparae were confined in a plastic jar with pieces of tough snowbell bark. Later, copulating sexuales and eggs were found between the pieces. These facts show that sexuales of C. nekoashi do not take food at all.
