The grapevine webworm is the larva of a geometrid moth (see Vine inchworm, under Vine).

Century Dictionary and Cyclopedia
    • n webworm Any one of several lepidopterous larvæ which feed more or less gregariously, and spin large webs into which they retire at night, or within which they feed during the day until the contained foliage is entirely devoured, when the web is enlarged. The tent-caterpillars, Clisiocampa americana and C. sylvatica, are web-worms. (See cut under tent-caterpillar.) The fall web-worm is the larva of the bombycid Hyphantria cunea. The garden web-worm is the larva of Eurycreon rantalis, a pyralid moth of the family Botidæ. This species is not gregarious, but the larvæ form individual webs near the roots of corn, cotton, cabbage, melon, potato, and other cultivated crops in the western United States.
