To evaluate the dietary antioxidant content of insects, we analyzed the hydrophilic oxygen radical absorbance capacity（H-ORAC） of silkworms（Bombyx mori Linnaeus）, and rice grasshoppers（Oxya yezoensis Shiraki）, which have been used as edible insects in Japan for many years, and Japanese buff-tip moths, Phalera flavescens（Bremer et Grey）, which feed on cherry blossom tree leaves. Among these three insects, the H-ORAC value was highest（7455±185 µmol Trolox eq./100 g FW）in O. yezoensis adults, followed by B. mori pupae（4417.5±270.1）, B. mori larvae（4280±189.1）, and P. flavescens larvae（4112.5±409.4）. The H-ORAC of all three insect species were more than twice those of most fresh vegetables, suggesting high antioxidant potential.
