Clutch size in a gregarious leaf-mining moth, Paraleucoptera sinuella, was examined in relation to leaf size and multiple oviposition. The field census of clutch distribution on a host plant, Salix miyabeana, showed that multiple oviposition occurred frequently, and clutches were distributed aggregatively among leaves. Large leaves were apt to receive multiple clutches. Clutch size was correlated positively with leaf size, but negatively with number of clutches per leaf. This implies that females recognize both leaf size and the presence of conspecific eggs and adjust clutch size accordingly. However, the two variables explained only a small amount of variation in clutch size. Thus, additional mechanisms are needed to explain the large amount of variation in clutch size of the leaf miner.
