Relationship between Date of Snowmelt, Flowering Onset of Corydalis ambigua, and Bumblebee Emergence (image) Hokkaido University Share Print E-Mail Caption The relationship between date of snowmelt (day of year), flowering onset of Corydalis ambigua, and bumblebee emergence. In years when snowmelt started early, flowering and bee emergence came early, but flowering occurred earlier than bee emergence, creating a mismatch. Credit Kudo G. and Cooper EJ.
