The larvae of a scarabaeid, Heptophylla picea MOTSCHULSKY, just after hatching were divided into four groups and each group (30 individuals) was reared under following conditions. The groups 1 and 2 were supplied with peat moss and a piece of carrot. The group 3 was supplied with only peat moss and group 4 was supplied with leaf mold. The group 1 was kept at 25°C and the others were kept at 18°C. Each group was kept in the dark.
All larvae of the groups 3 and 4 died within the 1st or 2nd instar. Twenty-three larvae of the group 2, and 9 larvae of the group 1 developed up to the 3rd (last) instar, respectively. The period of the 2nd instar of the group 1 was twice as long as that of the group 2.
In the result of present experiment, the most favorable condition for rearing the larvae of H. picea was the following requirements : use of peat moss as medium and of carrot as food and maintenance of temperature at 18°C.
