Aglais io, the European peacock,[3][4][5] or the peacock butterfly, is a colourful butterfly, found in Europe and temperate Asia as far east as Japan. The peacock butterfly is resident in much of its range, often wintering in buildings or trees. It therefore often appears quite early in spring.

Megalopyge opercularis is a moth of the family Megalopygidae. It has numerous common names, including southern flannel moth for its adult form, and puss caterpillar, asp, Italian asp, fire caterpillar, woolly slug, opossum bug,[3] puss moth, tree asp, asp caterpillar, and Donald Trump caterpillar[4] for its juvenile form.

The giant leopard moth (Hypercompe scribonia) is a moth of the family Erebidae. They are distributed through North America from southern Ontario, and southern and eastern United States through New England, Mexico, and south to Colombia.[2][3] The obsolete name, Ecpantheria scribonia, is still occasionally encountered.

Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail,[4] is a butterfly found throughout much of North America. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes. The species is named after the figure in Greek mythology, Polyxena  (pron.: /pəˈlɪksɨnə/; Greek: Πολυξένη), who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm  because the caterpillar feeds on parsley.[4]

Acronicta americana, the American dagger moth, is a moth of the family Noctuidae. It was originally described by Thaddeus William Harris in 1841 and is native to North America.

The saddleback caterpillar (Acharia stimuli, formerly Sibine stimulea) is the larva of a species of moth native to eastern North America. It is also found in Mexico.[1] The species belongs to the family of slug caterpillars, Limacodidae.

Eacles imperialis, the imperial moth, is a member of the family Saturniidae and subfamily Ceratocampinae. It is found mainly in the East of South America and North America, from the center of Argentina to south Canada.[1] The species was first described by Dru Drury in 1773.

Antheraea polyphemus, the Polyphemus moth, is a North American member of the family Saturniidae, the giant silk moths. It is a tan-colored moth, with an average wingspan  of 15 cm (6 in). The most notable feature of the moth is its large, purplish eyespots on its two hindwings. The eyespots give it its name – from the Greek myth of the cyclops Polyphemus. The species was first described by Pieter Cramer in 1776. The species is widespread in continental North America, with local populations found throughout subarctic Canada and the United States. The caterpillar can eat 86,000 times its weight at emergence in a little less than two months. Polyphemus moths are considered to be very polyphagous, meaning they eat from a wide variety of plants.[2]
