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.
Orgyia leucostigma, the white-marked tussock moth, is a moth in the family Erebidae. The species was first described by James Edward Smith in 1797. The caterpillar is very common especially in late summer in eastern North America, extending as far west as Texas, California, and Alberta.
The hemlock moth, also known as the defoliating hemlock moth or poison hemlock moth, is a nocturnal moth species of the family Depressariidae.

The moth is now widespread throughout the northern half of the United States, southern Canada, northern Europe, and, more recently, New Zealand and Australia. The larval form grows to around 10 mm, while the adults wingspan is between 17 mm and 19 mm.

Archips semiferanus is a species of moth in the family Tortricidae, and one of several species of moth commonly known as oak leafroller or oak leaf roller. The larvae feed on the leaves of oak trees in the eastern United States and southeastern Canada and are a major defoliator of oak trees, which can lead to tree mortality. In Pennsylvania in the late 1960s and early 1970s, oak leafrollers defoliated over 1,045,000 acres (423,000 ha).
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.
Eulithis testata, the chevron, is a moth of the family Geometridae. The species was first described by Carl Linnaeus in 1761. It is found in both the Palearctic and the Nearctic realms. In the Palearctic it ranges from Great Britain and Scandinavia, south to the Alps, east through Russia and the Russian Far East to Japan. In North America, it is found from Newfoundland to Vancouver Island and Alaska, south in the east to about New Jersey and in the west to Colorado.
Scopula junctaria, the simple wave, is a moth of the family Geometridae. The species was first described by Francis Walker in 1861. It is found in the whole of Canada and the northern United States, south to Maryland, Arizona, and California.

It is found from India to Indochina, Sundaland, Sulawesi, the Philippines, Sri Lanka, the Solomon Islands, Thailand, Taiwan, New Guinea and Australia, where it has been recorded from Queensland. It is a major defoliating pest in tea plantations.
