What is the approximate maximum length reached by a Woolly Bear caterpillar when fully developed before seeking shelter?
Answer
1 to 1.5 inches
When the Woolly Bear caterpillar has completed its feeding phase and is preparing for its overwintering period, it attains its maximum size for that larval stage. At this point of full development, measurements taken from the head end to the posterior end typically fall within the range of one inch up to one and a half inches. This size threshold is relevant as it signifies the caterpillar is physiologically ready to enter diapause and utilize its biochemical adaptations to survive the cold.
