active in spring and summer. The forage looper (C. erechtea) has been observed as an early spring in Kansas, appearing by late March.

Larvae function as herbivores in grassland and agricultural . Caterpillars contribute to nutrient cycling through consumption and processing of herbaceous plant material.
Human Relevance
The forage looper and related are common in lawns and pastures. Caterpillars feed on clover and alfalfa, potentially affecting forage crops, though economic impact is generally minor. are frequently encountered by naturalists and photographers at blacklight setups.
