Extract

As mentioned by Morris (1942), the forest entomologist is frequently faced with the practical problem of ascertaining the identity of certain insects which have defoliated the trees and disappeared before his arrival. Cast skins and head capsules provide a difficult and uncertain means of identification; and the kinds of damage done by the insects often are alike to such an extent that they are non-specific. There remains the abundant fecal pellet deposit, commonly called frass, which, if studied carefully, is a reliable means of identifying many species.
