During which typical fall months do Woolly Bears become highly visible preparing for overwintering?

Answer

September into November

The conspicuous activity period for the Woolly Bear caterpillar, characterized by them crossing open spaces like roads and driveways, is directly linked to their preparation for the cold season. This migration, aimed at finding suitable shelter for diapause, predominantly occurs during the autumn months when temperatures begin to drop significantly. The established timeframe during which these caterpillars are most frequently observed undertaking this search for overwintering sites spans from September and continues through November, marking their transition out of active feeding near summer host plants.
