Dyars Woad Cuttings in Bottles of Water
An effective method of raising caterpillars of the checkered white in the spring is to place caterpillars on cuttings of common mustards. This is dyars woad; considered an invasive and undesirable weed in the Western U.S. However, caterpillars of the checkered white, cabbage white, large marble, desert marble, olympia marble, spring white, and julia orangetip ALL feed fine on dyars woad (Isatis tinctoria.)
