The hungry caterpillars

Cinnabar moth caterpillars feed on tansy ragwort plants in a field near Elkton in rural western Oregon on Friday, July 6, 2018. The cinnabar moth was introduced to North America to help control  invasive noxious ragwort plants. 
The caterpillars buildup toxins in their bodies while feeding on the weeds and their striking coloration is believed to warn predators of their unpalatability.
