The carrot caterpillar hides among and feeds on the leafy foliage in carrot fields. A man demonstrates how difficult it is to detect and remove them from the carrot plants. They propel themselves with their six feet and twelve suction cups. To ward off enemies, they display two horns which secrete a malodorous liquid. Before the chrysalis stage of their development, they attach themselves to a surface and two days later burst from their shell. After spending the winter as a chrysalis, they emerge as swallowtail butterflies. Once they have bathed their wings in dew and dried off, they are ready to fly. (Library of Congress)
