Sulfur is a chemical element with symbol S and atomic number 16.
The Pieridae are a large family of butterflies with about 76 genera containing about 1,100 species, mostly from tropical Africa and tropical Asia with some varieties in the more northern regions of North America and Eurasia. Most pierid butterflies are white, yellow, or orange in coloration, often with black spots. The pigments that give the distinct coloring to these butterflies are derived from waste products in the body and are a characteristic of this family. The family was created by William John Swainson in 1820.
Zerene eurydice, the California dogface butterfly, belongs to the family Pieridae and is a sister genus to Colias.The Zerene eurydice and the Colias both share the "characteristic of having yellow-orange and black wing coordination." Additionally the,"Colias and Zerene eurydice males have bright UV patterns on their wings."There are only two species of the Zerene, the Zerene eurydice, and the Zerene cesonia, also known as the Southern dogface. A study that collected mitochondrial DNA from various Colias butterfly species found that Z. eurydice had decreased divergence from the ingroup, highlighting how closely related these two genera are. This species is endemic to California, and is California's state insect. The California dogface butterfly varies in its wing color and pattern.
Phoebis sennae, the cloudless sulphur, is a mid-sized butterfly in the family Pieridae found in the Americas. There are several similar species such as the yellow angled-sulphur, which has angled wings, statira sulphur, and other sulphurs, which are much smaller. The species name likely comes from the American senna which serves as the host plant for cloudless sulphur caterpillars.
Several taxa of butterflies are collectively called the Sulphurs or Sulfurs:
The Limenitidinae are a subfamily of butterflies that includes the admirals and relatives. The common names of many species and genera reference military ranks or – namely the Adoliadini – titles of nobility, in reference to these butterflies' large size, bold patterns, and dashing flight. In particular, the light stripe running lengthwise across the wings of many Limenitidini has reminded earlier authors of officers' shoulder marks and epaulets.
Colias eurytheme, the orange sulphur, also known as the alfalfa butterfly and in its larval stage as the alfalfa caterpillar, is a butterfly of the family Pieridae, where it belongs to the lowland group of "clouded yellows and sulphurs" subfamily Coliadinae. It is found throughout North America from southern Canada to Mexico.
Colias is a genus of butterflies in the family Pieridae. They are often called clouded yellows; the North American name "sulphurs" is elsewhere used for Coliadinae in general. The closest living relative is the genus Zerene, which is sometimes included in Colias.
Gonepteryx is a genus of butterflies in the family Pieridae, which contains about 1,100 species. They live in Europe, Asia, and Northern Africa. They are commonly known as brimstones for the bright yellow colour of the wings of most species. These share the same name as the much larger tropical genus Anteos. These inhabit much of central and South America and also North America. This species are known for being the kings of butterfly longevity. 10-13 months is the lifespan for many temperate species. Anteos, however, is much shorter lived. The adults will often mimic ivy leaves at rest. Male brimstone butterflies can withstand cooler temperatures and are able to fly after just 4 months in hibernation. Female brimstone butterflies need warmer climates to survive, and therefore are in hibernation longer. The male butterflies have a longer life span as they are more resilient to a wider range of temperatures, unlike the female.
Ithomiini is a butterfly tribe in the nymphalid subfamily Danainae. It is sometimes referred to as the tribe of clearwing butterflies or glasswing butterflies. Some authors consider the group to be a subfamily (Ithomiinae). These butterflies are exclusively Neotropical, found in humid forests from sea level to 3000 m, from Mexico to Argentina. There are around 370 species in some 40–45 genera.
Zerene cesonia, the southern dogface, is a North and South American butterfly in the family Pieridae, subfamily Coliadinae.
Zerene is a genus of butterflies in the family Pieridae commonly called dogfaces. The closest living relative is the genus Colias. They are migratory.
Colias alexandra, the Queen Alexandra's sulphur, Alexandra sulphur, or ultraviolet sulfur, is a butterfly in the family Pieridae found in western North America. Its range includes Alaska to the Northwest Territories and south to Arizona and New Mexico.
