Eurema hecabe, the common grass yellow, is a small pierid butterfly species found in Asia, Africa and Australia. They are found flying close to the ground and are found in open grass and scrub habitats. It is simply known as "the grass yellow" in parts of its range; the general term otherwise refers to the entire genus Eurema.
Eurema brigitta, the small grass yellow or broad-bordered grass yellow, is a small butterfly of the family Pieridae, that is, the yellows and whites. It is found in India, other parts of Asia, Australia and Africa.
Eurema blanda, the three-spot grass yellow, is a small butterfly of the family Pieridae which is found in Sri Lanka, India and southeast Asia.
Catopsilia pyranthe, the mottled emigrant, is a medium-sized butterfly of the family Pieridae found in south Asia, southeast Asia, and parts of Australia.
Eurema is a widespread genus of grass yellow butterflies in the family Pieridae.
In plant biology, nyctinasty is the circadian rhythm-based nastic movement of higher plants in response to the onset of darkness, or a plant "sleeping". Nyctinastic movements are associated with diurnal light and temperature changes and controlled by the circadian clock. It has been argued that for plants that display foliar nyctinasty, it is a crucial mechanism for survival; however, most plants do not exhibit any nyctinastic movements. Nyctinasty is found in a range of plant species and across xeric, mesic, and aquatic environments, suggesting that this singular behavior may serve a variety of evolutionary benefits. Examples are the closing of the petals of a flower at dusk and the sleep movements of the leaves of many legumes.
Eurema nicippe, the sleepy orange, is a North American butterfly in the family Pieridae. It is also found in the West Indies, Costa Rica and Belize.
Eurema lisa, commonly known as the little yellow, little sulphur or little sulfur, is a butterfly species of subfamily Coliadinae that occurs in Central America and the southern part of North America.
Eurema mexicana, the Mexican yellow, sometimes called the wolf-face sulphur, is a North and South American butterfly in the family Pieridae. It occurs mainly in Mexico but occasionally is found in central and southwestern United States and rarely in Canada.
Eurema proterpia, the tailed orange, is a North and South American butterfly in the family Pieridae.
Eurema desjardinsii, the angled grass yellow, is a butterfly of the family Pieridae, found in Africa.
Eurema smilax, the small grass yellow, is a small pierid butterfly species found in Australia, with some additional records from India, Indonesia and Niger.
Eurema albula, the ghost yellow, is a butterfly in the family Pieridae. It is found from southern Texas south through the West Indies and mainland tropical Central and South America to Brazil. The habitat consists of tropical forests and second growth.
Eurema boisduvaliana, commonly known as Boisduval's yellow, is a butterfly in the family Pieridae. It is found from Costa Rica north to Mexico. Rare strays may be found in southern Florida, but it is a regular migrant to south-eastern Arizona, south-western New Mexico, and southern Texas. The habitat consists of subtropical forests and forest edges, scrubs, roadsides and pastures.
Eurema nicevillei, the Malayan grass yellow, is a butterfly in the family Pieridae. It is found in Thailand, southern Burma, Peninsular Malaysia, Borneo, and Sumatra.
Eurema senegalensis, the forest grass yellow, is a butterfly in the family Pieridae. It is found in Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Togo, Benin, Nigeria, Cameroon, Equatorial Guinea, the Republic of the Congo, the Democratic Republic of the Congo, western Uganda, western Kenya, Tanzania and Zambia. The habitat consists of forests and heavy woodland.
Chamaecrista rotundifolia, the round-leaf cassia, also known as pasto rastiero, roundleaf sensitive pea, and Wynn cassia, is a short-lived perennial or self-generating annual plant in the subfamily Caesalpinioideae of the family Fabaceae. It originated in North America, Mesoamerica, the Caribbean, and Tropical South America but is grown in other parts of the world today. It grows in dry soils and areas of low rainfall, as well as in low-fertility and acidic soils with high levels of solubilized aluminum. It can also reduce erosion and runoff over time. These factors make it a potential asset to farmers in the African Subtropics and elsewhere where soil quality is a barrier to farming. It serves as a source of feed for livestock and acts as a green fertilizer, raising soil quality and nutrient content which can improve yields. These combined benefits make round-leaf cassia a potential solution to many problems faced by poor farmers and their communities.
