Information: - The Danaini are a tribe of brush - footed butterflies ( family Nymphalidae ) . Their type genus Danaus contains the well - known Monarch Butterfly ( D. plexippus ) and is also the type genus of the tribe 's subfamily , the milkweed butterflies ( Danainae ) . The Danaini do not have a fixed colloquial name ; for the entire tribe but in particular for subtribe Danaina the term tiger butterflies is occasionally used in reference to the numerous species in several genera commonly known as '' tigers '' . - Milkweed butterflies are a subfamily, Danainae, in the family Nymphalidae, or brush-footed butterflies. They lay their eggs on various milkweeds on which their larvae (caterpillars) feed. Historically, this group had been considered a separate family, Danaidae. - Zoology (UK: , zoo-OL-luh-jee; US: , zoh-OL-luh-jee) or animal biology is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , "zion", i.e. "animal" and , "logos", i.e. "knowledge, study". - The monarch butterfly or simply monarch ("Danaus plexippus") is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. Other common names depending on region include milkweed, common tiger, wanderer, and black veined brown. It may be the most familiar North American butterfly, and is considered an iconic pollinator species. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of The viceroy butterfly is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing. - The Nymphalidae are the largest family of butterflies with about 6,000 species distributed throughout most of the world. These are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings. - In Greek mythology Danaus ("Danaos"), was the twin brother of Aegyptus, a mythical king of Egypt. The myth of Danaus is a foundation legend (or re-foundation legend) of Argos, one of the foremost Mycenaean cities of the Peloponnesus. In Homer's "Iliad", "Danaans" ("tribe of Danaus") and "Argives" commonly designate the Greek forces opposed to the Trojans. - In biological classification, especially zoology, the type genus is the genus which defines a biological family and the root of the family name. - A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains.
