Research Abstract
I examined geographic variation of larvae growth pattern of the Japanese rhinoceros beetle Trypoxylus dichotomus. Larvae originated from ca. 15 populations were reared under common laboratory environment. The larval body mass was measured every 5 days, and growth parameters of each individuals were estimated. I found a strong positive relationship between growth rate and latitude. The rapid growth of beetles from high latitudes is probably adaptation for completion of development before winter. I also examined the larval growth pattern of northernmost, Hokkaido populations that were introduced ca. 50 years ago. However, I found no evidence of rapid adaptation of the growth pattern of the Hokkaido populations.
