Speranza is a genus of moths in the family Geometridae erected by John Curtis in 1828.
The following species are classified in the genus. [1] This species list may be incomplete.
The winter moth is a moth of the family Geometridae. It is an abundant species in Europe and the Near East and a famous study organism for evaluating insect population dynamics. It is one of very few lepidopterans of temperate regions in which adults are active in late autumn and early winter. The adults use endothermy for movement in these cold temperatures. The females of this species are virtually wingless and cannot fly, but the males are fully winged and fly strongly. After the initial frosts of late fall, the females emerge from their pupae, walk to and up trees and emit pheromones in the evening to attract males. After fertilization, they ascend to lay, on average, around 100 eggs each. Typically, the larger the female moth is, the more eggs she lays.
Operophtera is a genus of moths in the family Geometridae erected by Jacob Hübner in 1825.
Eusarca confusaria, the confused eusarca, is a moth species of the family Geometridae that occurs in North America and Brazil. It is the only member of the genus Eusarca that inhabits the northern portion of the United States and Canada.
Operophtera bruceata, the Bruce spanworm, hunter's moth, or native winter moth is a moth of the family Geometridae. The species was first described by George Duryea Hulst in 1886. It is found from coast to coast in southern Canada and the northern parts of the United States.
Speranza pustularia, the lesser maple spanworm, is a moth of the family Geometridae. It is found from Nova Scotia to Florida, west to Mississippi, north to North Dakota and Saskatchewan.
Macaria loricaria, the false Bruce spanworm or Eversmann's peacock, is a moth of the family Geometridae. It is found from Fennoscandia and the Baltic states to Sakhalin. It is also found in North America, where it is found from Alaska to Newfoundland and New York, south to Colorado.
Ennomos subsignaria, the elm spanworm moth, is a moth of the family Geometridae. The species was first described by Jacob Hübner in 1823. It is found in North America from Texas (south) to Alberta (northwest) and east to the Atlantic coast. It is recorded infrequently in Great Britain through accidental importation in asparagus.
Lycia ursaria, the stout spanworm moth or bear, is a moth of the family Geometridae. The species was first described by Francis Walker in 1860. It is found in southern Canada and the northern United States, south to New Jersey and Iowa.
