Changes in the survivorship, distribution and movement pattern during the adult life of a damselfly, Lestes temporalis (Zygoptera: Odonata)

Survivorship, distribution and movement of adult Lestes temporalis Selys were investigated by marking individuals uniquely in Kyoto, Japan. Emergence began in mid-June and reproductive activity was observed from mid-September. The maximum length of the pre-reproductive period was about 90 days. Most immature adults flew away from water in June and July. In August most adults became residential in the woods. Through these months survival rate for both sexes was extremely high. Before the breeding season started, mature males shifted their distribution sites to water. Thereafter mature females returned to the pond at the beginning of the breeding season. After this they showed a back and forth movement between the pond and the surrounding wood during the breeding season, to oviposit and rest respectively. The survival rate decreased rapidly immediately after the start of the breeding season.
