Why should I continue looking for a phenophase even after it has passed?
Many phenophases may occur two or more times in a year. Many birds lay a second clutch of eggs in the summer after the first clutch has fledged. If a frost or pest kills many of the leaves on a tree, it will often have a second flush of new leaves. In dry climates, some phenophases repeat after multiple rain events. Also, climate change is changing the timing and frequency of life cycle events, which is extremely important to capture! For example, as temperatures warm and growing seasons get longer, many species are reproducing more frequently—some birds are having more broods, some plants flower more often, and insects like butterflies and dragonflies may go through more generations in a single year.
