Cerodontha scirpivora
Cerodontha scirpivora is a leaf miner fly in the family Agromyzidae. The species was described by Spencer in 1969. Its larvae create mines between the layers of leaves in grasses, sedges, and rushes. The specific epithet "scirpivora" indicates an association with Scirpus (bulrushes), a genus of sedges.
Globia oblonga
Oblong Sedge Borer Moth, oblong sedge borer
Globia oblonga is a noctuid moth commonly known as the oblong sedge borer. First described by Grote in 1882, this species was formerly placed in the genus Capsula before that name was abandoned due to a homonym conflict with a mollusk genus. The species is notable for its specialized larval biology: early instars are leaf miners on emergent aquatic plants, while later instars transition to stem-boring below the water line. Adults are medium-sized moths with wingspans of 35–50 mm.
Globia subflava
Yellow Sedge Borer Moth, Subflava Sedge Borer
Globia subflava is a noctuid moth native to North America, commonly known as the yellow sedge borer or subflava sedge borer. The species was described by Augustus Radcliffe Grote in 1882 and is characterized by its stem-boring larval habit in wetland plants. Adults are active in mid-summer with a single annual generation.
Monochroa robusta
Monochroa robusta is a small gelechiid moth described by Annette Frances Braun in 1921. The species is known from limited records in Ohio and South Carolina, with a wingspan of 11–12 mm. Larvae are leaf miners on Scirpus atrovirens, creating distinctive mines that begin as small transparent blotches and expand toward the leaf tip.
