The actual times of the collections are indicated by the bars on the time scale. SS: sunset; SR: sunrise; HW1 and HW2: high tides; LW1 and LW2: low tides. Results and Discussion The emergence patterns of D. asialica were summarized in each season. Emergence pattern in March and May Figure 1 shows the number of animals collected during each hour of the night in May. Most animals were col- lected near the time of the night high tide. When high tides (HW1 and HW2) occurred around the time of sun- rise and sunset (6-7 days surrounding the first quarter of the moon), the activity exhibited two peaks in the night, one shortly after sunset and another before sunrise. Col- lections in March showed a similar pattern (data not shown)..
