• A phenomenon similar to the phase variation in armyworms was observed in the coloration of larvae of Libythea celtis when they were reared at different densities. It is the first record of phase variation in butterflies. The body color showed a remarkable change from green to black. When larvae were reared in isolation all individuals became pale in color, and with the increase of density larvae became dark. Larvae reared in crowds developed more rapidly and were more active than those reared in isolation, and adult butterflies emerged from crowded cultures became smaller than those from isolated cultures. These characters are similar to those of other insects which show phase variation, but the different point is that larval walking activity and tolerance to starvation showed no difference between the low-density and the high-density types. L. celtis is not a migrant species and the ecological significance of phase variation of this insect can not be understood in relation to migration as in armyworms and locusts.
