Phenology is the study of recurring plant and animal life cycle changes in relation to the weather. Some changes are temperature-dependent, not calendar-dependent. The opening of some buds and the emergence of some insects from the ground are related to the accumulated warmth of that season. It isn't just superstition that some events occur simultaneously every year, but on dates that change from year to year. It is the result of two events being triggered by the accumulating warmth having reached a certain threshold. It's about what is happening, not a premonition of what will happen based on the width of woolly bear caterpillar stripes!
