Apamea devastator
glassy cutworm moth, glassy cutworm
Apamea devastator, commonly known as the glassy cutworm moth, is a noctuid moth of northeastern North America. The adult has a wingspan of 35–40 mm and flies from May to September. The larva is a subterranean cutworm that feeds on grasses, attacking roots and basal stems. The species is economically significant as a pest of turfgrass and agricultural grasses.
Diabrotica virgifera zeae
Mexican corn rootworm
Diabrotica virgifera zeae, the Mexican corn rootworm, is a subspecies of the western corn rootworm complex and a significant agricultural pest of corn (Zea mays) in Mexico and parts of the southern United States. Larvae feed on corn roots, causing damage that can lead to reduced yield, stunting, and plant lodging. Unlike the western corn rootworm subspecies (D. v. virgifera), the Mexican corn rootworm has been documented to damage corn following sorghum rotation in parts of South Central Texas, though this remains rare. Adults feed on corn silks, pollen, and leaves. The species has one generation per year, with eggs laid in soil during summer and fall, hatching the following spring when corn roots become available.
