Description and Identification
Caterpillar
The Dakota Skipper caterpillar is characterized by its light brownish-gray coloration with a distinctive black head bordered in white. Their bodies are smooth, and they primarily feed on grass leaves during the night. These resourceful creatures also construct shelters made of silken tubes lined with grass, providing them with protection and comfort.
