Orthosia
Guides
Orthosia arthrolita
Orthosia arthrolita is a species of cutworm or dart moth in the family Noctuidae, first described by Harvey in 1875. It belongs to a genus of early spring-flying moths, with adults typically active during the brief window before foliage fully develops. The species occurs in North America, though specific details about its biology remain poorly documented compared to better-known congeners such as Orthosia hibisci.
Orthosia ferrigera
Orthosia ferrigera is a species of cutworm or dart moth in the family Noctuidae, first described by Smith in 1894. It occurs in North America and is assigned MONA/Hodges number 10482. Like other members of the genus Orthosia, it is likely an early spring-emerging species, though specific biological details remain poorly documented.
Orthosia revicta
Subdued Quaker, rusty whitesided caterpillar
Orthosia revicta, commonly known as the Subdued Quaker, is a species of cutworm moth in the family Noctuidae. It is native to North America and has been recorded across Canada and the northern United States. Like other members of the genus Orthosia, it is an early spring-emerging species. The species was originally described by Morrison in 1876 under the basionym Taeniocampa revicta.
Orthosia segregata
Separated Quaker
Orthosia segregata, commonly known as the Separated Quaker, is a species of cutworm or dart moth in the family Noctuidae. It belongs to the genus Orthosia, a group of early spring-flying moths often referred to as "quakers." The species was described by Smith in 1893 and is native to North America, with records from western Canadian provinces including Alberta, Manitoba, and Saskatchewan. Like other Orthosia species, it likely has a single generation per year with adults emerging in early spring.
Orthosia tenuimacula
Orthosia tenuimacula is a species of cutworm moth in the family Noctuidae, first described from North America in 1913. The species belongs to a genus of early spring-emerging moths, with adults typically active during March and April. Like other Orthosia species, it likely overwinters in the pupal stage. The specific epithet 'tenuimacula' (slender spot) refers to a marking on the forewing. Very few observations exist for this species, suggesting it may be genuinely rare, undercollected, or restricted to specific habitats.
Orthosia transparens
Orthosia transparens is a species of cutworm or dart moth in the family Noctuidae. It is found in North America. The species has been assigned MONA (Moth Photographers Group) or Hodges number 10479. Like other members of the genus Orthosia, it is likely an early spring-flying species.
