The butter-bur leaf-miner (Acidia japonica Shiraki) has 2 generations in a year and the adults emerge in spring (May-June) and autumn (September-October) in Tottori Prefecture. They oviposit in the tissues of the leaves of butter-bur (Petasites japonicus Miq.), and the larvae make the serpentine mines at first, and then the mines change gradually to the blotch ones. In the serpentine mines the larvae eat mainly the pallisade parenchym and sometimes eat the spongy parenchym, but in the blotch mines they eat the pallisade parenchym absolutely. I could find no larva in any place in the spring of this year. The duraton of the egg stage is unknown, the larval period is about 14 days in autumn (the mean daily air temperatures 17°-12℃), and we can estimate 3 instars. The area of the mine which is made by one larva is about 21.4 s. c. m. The habitat of this species is restricted and small, and the larvae may be found in the shady, moist places in small numbers. They hibernate in the pupal stage. Adults emerge in the morning. Adult females could live on the cane sugar water (20%) for about 7 days. The mean daily air temperatures of the period of emergence in the spring is between 19℃ and 21℃. The larvae which are picked out of the mines can easily invade into the tissue of the leaves to make mines. The larvae cease movements in the low air temperatures (11°-12℃).
