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.
Apamea geminimacula
A medium-sized noctuid moth in the cutworm genus Apamea. The species was described by Dyar in 1904 and occurs in North America and Middle America. Like other Apamea species, it is difficult to identify due to individual variation and overlapping morphological traits with congeners.
Apamea inebriata
drunk apamea
Apamea inebriata, commonly known as the drunk apamea, is a noctuid moth species described by Ferguson in 1977. It occurs along the Atlantic coast of North America with a disjunct distribution pattern consisting of scattered local populations. The species remains poorly known, with limited documentation of its biology and ecology.
Apamea inordinata
Ornate Apamea
Apamea inordinata is a noctuid moth commonly known as the Ornate Apamea. It is distributed across much of North America, with records from numerous U.S. states and Canadian provinces. The species has a wingspan of approximately 34 mm. It is listed as threatened in Connecticut, indicating conservation concern in at least part of its range.
Apamea lignicolora
Wood-colored Apamea Moth, Wood-coloured Quaker
Apamea lignicolora is a noctuid moth native to North America, with a wingspan of 45–50 mm. The species was described by Guenée in 1852 and occurs across much of Canada and the United States. Larvae feed on various grasses including couch grass (Agropyron repens). Two subspecies are recognized: A. l. lignicolora and A. l. quaesita.
Apamea lintneri
sand wainscot moth, Sand Wainscot
