Polygonia interrogationis, commonly called the question mark butterfly, is a North American nymphalid butterfly. It lives in wooded areas, city parks, generally in areas with a combination of trees and open space. The color and textured appearance of the underside of its wings combine to provide camouflage that resembles a dead leaf. The adult butterfly has a wingspan of 4.5–7.6 cm (1.8–3.0 in). Its flight period is from May to September. "The silver mark on the underside of the hindwing is broken into two parts, a curved line and a dot, creating a ?-shaped mark that gives the species its common name."
Humulus japonicus, known as Japanese hops, is an ornamental plant in the family Cannabaceae. Some authorities have it as a synonym of Humulus scandens.

The Appalachian azure is a butterfly in the gossamer wings family Lycaenidae. The male is light blue on the upperwing with a narrow, dark line running along the edge of the forewing. The underwing is chalky white and is dotted with small, pale dark spots. The very back of the hindwing has a row of dark spots running along the edge and contained by a faint zigzagging band. Females are similar to the males but have broad dark wing borders instead of the male's narrow ones. The adult butterfly has a 1.1–1.4-inch (2.8–3.6 cm) wingspan. It is the largest azure in the area.
Celastrina ladon, the spring azure or echo blue, is a butterfly of the family Lycaenidae.

The upper surface is pale blue with an extensive dusting of white scales, especially on the hindwing. In some females the blue is almost entirely replaced by white with a small amount of blue near the wing bases. Females have a broad blackish-grey band on the outer third and costa of the forewing. The underside is chalky white to pale grey with tiny dark grey spots and a zigzagged submarginal line on the hindwing.
Celastrina serotina, the cherry gall azure, is a butterfly of the family Lycaenidae. It is found across North America as far north as the treeline. Its flight time is between mid-May and mid-June in eastern Ontario after the spring azure and before the summer azure. The larva has been reported to feed on galls of eriophyid mites and apparently also on the mites themselves, making them one of the rare species of carnivorous Lepidoptera. It is commonly found around woodland roads of upland mixed deciduous hardwood forests which are surrounded by wetlands.
Spiraea alba, commonly known as meadowsweet, white meadowsweet, narrowleaf meadowsweet, pale bridewort, or pipestem, is native to the wet soils of the Allegheny Mountains and other portions of eastern North America, but is currently endangered in the state of Missouri.
