Economic Host(s)

A vast range of horticultural and agricultural crops.

Symptoms/Signs

Early instars feed on leaves while later instars begin to feed below ground on roots of their host. Feeding on the leaves often produces windowpanes (just the lower epidermis remaining). External feeding results in fallen leaves and root feeding leaves obvious holes. Subterranean feeding by late instars causes toppling of plants.
