Abstract:
The external morphologies of the eggs of seven species of grasshoppers were studied with the aid of an electron microscope. The species were Boopedon diabolicum Bruner, Schistocerca cohni Song, Sphenarium purpurascens (Charpentier), Brachystola mexicana Bruner, Melanoplus differentialis (Thomas), Syrbula admirabilis (Uhler), and Melanoplus lakinus (Scudder). The eggs were elongated with rounded ends and provided reliable characteristics that allow identification of the seven species. Eggs of some of the seven species were hexagonal. Brachystola mexicana and Sphenarium purpurascens produced fewer eggs that were larger. The differential characteristics of the seven species and their general systematics are described to differentiate the taxa.
