The painted lady uses over 300 recorded host plants according to the HOSTS database. For raising in the classroom one need only sprout a bed of black oil sunflower seeds, as are used for bird seed. The caterpillars will eat the true adult leave (not the sprouts) and in this way one may inexpensively produce many host plants. Soak the seeds for eight hours in 10% diluted household bleach (1 pt bleach, 9 pts water) to ensure a disease free, even sprouting. Place the seeds upon the surface of the soil and keep moist until they grow roots and can be watered normally.

“The rule for hospitality and Irish “help,” is, to have the same dinner every day throughout the year. At last, Mrs. O’Shaughnessy learns to cook it to a nicety, the host learns to carve it, and the guests are well served.”
—Ralph Waldo Emerson (1803–1882)
“Probably if our lives were more conformed to nature, we should not need to defend ourselves against her heats and colds, but find her our constant nurse and friend, as do plants and quadrupeds.”
—Henry David Thoreau (1817–1862)
