Grapevine Looper, Eulithis diversilineata (Hubner) (Lepidoptera: Geometridae): Common in four counties in 1985.

Description

Overwintering eggs hatch in late spring. Larvae range in color from yellow green to red to nearly black.  They feed on foliage for six to eight weeks.  The pupal stage lasts about 10 days and is spent in a loose web spun on a leaf or berry cluster.  Adults emerge in midsummer and lay overwintering eggs.  There is one generation annually.

Damage

The larval stage feeds on foliage for six to eight weeks during the summer and are considered to be a minor pest in Ohio vineyards.  Vineyards receiving regular treatment for other pests seldom experience a problem with grapevine looper.
