The small heath is a butterfly species belonging to the family Nymphalidae, classified within the subfamily Satyrinae. It is the smallest butterfly in this subfamily. The small heath is diurnal and flies with a noticeable fluttering flight pattern near the ground. It rests with closed wings when not in flight. It is widespread in colonies throughout the grasslands of Eurasia and north-western Africa, preferring drier habitats than other Coenonympha, such as salt marshes, alpine meadows, wetlands, and grasslands near water. However, habitat loss caused by human activities has led to a decline in populations in some locations.

Coenonympha tullia, the large heath or common ringlet, is a butterfly in the family Nymphalidae. It flies in a variety of grassy habitats, including roadsides, woodland edges and clearings, prairies, bogs, and arctic and alpine taiga and tundra. It is a poor flyer, but can sometimes be found along ditches seeking new grounds. It is a holarctic species found in northern Europe, east across the Palearctic and across North America. The species was first described by Otto Friedrich Müller in 1764.
