Here's a breakdown:
* Late summer/early fall: Woolly bears reach their full size and stop eating.
* October/November: They search for a suitable spot to pupate, typically under leaf litter, logs, or rocks.
* Pupation: They spin a cocoon around themselves and transform into a pupa.
The exact timing can vary depending on the location and weather conditions. However, the general rule of thumb is that woolly bears pupate in the fall, usually between October and November.
They remain in the pupa stage throughout the winter and emerge as adult moths in the spring.
