Few species are of economic importance though some are defoliators of
fruit trees (Kalshoven 1981). Their role as defoliators of rain forest
trees and seedlings has yet to be elucidated. They may have some value as
an indicator group for monitoring rain forest type, and are frequently
taken in light-traps set on the forest floor amid the understorey, though
they are more numerous in samples made with the light overlooking the
canopy.
