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.
Senna obtusifolia, known by common names including Chinese senna, American sicklepod and sicklepod, is a plant in the genus Senna, sometimes separated in the monotypic genus Diallobus. It grows wild in North, Central, and South America, Asia, Africa, and Oceania, and is considered a particularly problematic weed in many places. It has a long-standing history of confusion with Senna tora and that taxon in many sources actually refers to the present species.
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.
Senna bicapsularis is a species of the legume genus Senna, native to northern South America, from Panama south to Venezuela and Colombia, and also the West Indies. Common names include rambling senna, winter cassia, Christmas bush, money bush, and yellow candlewood. In Florida, Senna pendula is usually cultivated as, and misapplied to, S. bicapsularis.
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.
Nathalis iole, the dainty sulphur or dwarf yellow, is a North American butterfly in the family Pieridae.
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 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.
Eurema portoricensis, the Puerto Rican yellow, is a butterfly in the family Pieridae. It is found in Puerto Rico.
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.
