On the Visitor Center

I stopped at Canoe Creek State Park and helped set up an activity for tomorrow at the visitor center. Heidi, the environmental educator, pointed out a roosting bat behind the light outside of the door. After we were done, I walked around the outside of the building looking for other animals coming up with a woolly bear caterpillar, an assasin bug, and the bat. All these animals are preparing for winter in their own way. Woolly bear caterpillars are the folk weather forecasters with cinnamon red and black stripes. The caterpillars find a safe place to overwinter - under rocks, in the leaf litter, and in logs. In the spring, they'll spin their coccoons and Isabela tiger moths will emerge. This woolly bear will hopefully be moving to more sheltered location for the winter. The assasin bug pictured here is one I frequently find in my own house. These overwinter in the cracks and crevices of houses, in rocky areas, and other sheltered spots. Known for their predatory behavior, these Hemipterans are quite adept at stalking prey. Their piercing sucking mouth part acts as a tube that exudes digestive juices and ingests the soupy nutrition it creates. Assassin bug is more of a general term, applying to some 3,000 species. The bat, probably a little brown, has found safety for today. I hope after a good day's rest this bat moves to a sheltered cave or some warmer abode. Temperatures are dropping into the 30s tonight.

What kind of winter will we be having? Did the woolly bear give any indication?
