Peacock butterfly (Inachis io), caterpillar, and pupa. Alexander Marshal, 162?-1682, was chiefly known as an illustrator of flowers and plants. In 1980, his expertise in painting insects also came to light, through this album of insect drawings. The album consists of 57 pages containing 129 watercolors of insects: butterflies, moths, caterpillars, beetles, locusts, spiders, flies, and crickets. The backs of Marshal's drawings contain notes in his own hand.
