Grape-leaf Folder
The caterpillar of this pretty little moth feeds upon the leaves of various wild and cultivated grapes, showing a preference for those species the leaves of which are thin and tender. The caterpillar is of a transparent green color, and is very lively when disturbed. The insects, which do considerable damage in vineyards, may be kept down by crushing the larvae and the pupae when found in the folded leaves, which are easily detected. The moth is found from Canada to the Gulf east of the Great Plains.
