Seasonal abundance of Phalaenoides glycine was studied in the field over three years. Numbers in the first generation were generally very low compared with those of the second generation. Defoliation by larvae was patchy. Data on the distribution of eggs and larvae in both first and second generations were fitted to Poisson and negative binomial distributions. Morisita's Index was used to measure the dispersion.
