Every fall I see hundreds of these scrambling around in near zero temperatures. I find this especially odd as we usually have our first snowfall by now. These also catch my eye as they’re the biggest caterpillars I’ve seen in the area. And mind the quality, as the photos were taken with an iPhone.

Winter Cutworm

Hi Grant,
Your caterpillars are known as the Winter Cutworm, the larva of the accidentally introduced, invasive exotic Large Yellow Underwing,
Noctua pronuba.  As you letter indicates, the caterpillars are active during the winter and they can even be found when there is snow on the ground.  See BugGuide for additional information.
