• The length of aquatic period and the growth rate in Cordulia aenea amurensis SELYS were studied by rearing and periodical sampling of the larvae. The eggs hatch on the 10th-17th day after oviposition made during late June-early August. In the pond Horai-numa near Sapporo, the newly hatched larvae attain ca. 3 mm in body length (BL) before the first winter. The growth rate in the medium sized larvae (BL 4-10 mm) is 27-55 μm/day during favorable season (water temperature 17-23℃) from late June to early September, while virtually no growth occurs from October to May. After the fourth overwintering, the larvae enter the final instar (BL 18-21 mm). Hibernating once more, they start metamorphosis and finally emerge during early-mid June. At least 80% of the population are regarded to undergo this 5 year life cycle, but some individuals may have an aquatic period of six years.
