This identification guide is dedicated to Annette F. Braun and T.N. Freeman, who did so much to improve our understanding of tiny moths and their caterpillars.

The caterpillars shown on the cover are (in clockwise order, from upper left): the spruce budworm (Choristoneura fumiferana), the festive pine looper (Nepytia species [undescribed]), the Comstock’s sallow (Feralia comstocki), and the larch silkworm (Hyalophora columbia columbia).
