Phenology is the study of plants' and animals' responses to seasonal changes. Bird migrations, insect emergences, and sequences of bloom are all examples of these annual cycles.

"My Little Bees"

For the past few years, I've been documenting the annual emergence, and expansion, of a colony of Colletes, Cellophane Bees, in my garden. Days of rain, which makes the soil workable, followed by temperatures in the 70s, seem to lead to their emergence. Soil temperatures must also be important.
