Uraniidae
Encyclopedia
The Uraniidae are a family
of moth
s containing four subfamilies, ninety genera
, and roughly seven-hundred species
. The family is distributed throughout the tropics
of Americas
, Africa
and Indo-Australia. Some of the tropical species are known for their bright, butterfly-like colors and are called sunset moths (for example Chrysiridia rhipheus). Such moths are apparently toxic and the bright colors are a warning to predators.
The family Uraniidae contains both diurnal and nocturnal species. The day-flying species are usually more strikingly colored and vibrant than the nocturnal individuals. Many diurnal species also have iridescent
scales and multiple tail
s, which often lead them to be mistaken for butterflies. In sharp contrast, the nocturnal species are generally small, pale-colored insect
s. The Uraniidae are similar to the Geometer Moths, to which they are related, but a different wing veining pattern distinguishes them.
Family (biology)
In biological classification, family is* a taxonomic rank. Other well-known ranks are life, domain, kingdom, phylum, class, order, genus, and species, with family fitting between order and genus. As for the other well-known ranks, there is the option of an immediately lower rank, indicated by the...

Moth
A moth is an insect closely related to the butterfly, both being of the order Lepidoptera. Moths form the majority of this order; there are thought to be 150,000 to 250,000 different species of moth , with thousands of species yet to be described...

Genus
In biology, a genus is a low-level taxonomic rank used in the biological classification of living and fossil organisms, which is an example of definition by genus and differentia...

Species
In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Tropics
The tropics is a region of the Earth surrounding the Equator. It is limited in latitude by the Tropic of Cancer in the northern hemisphere at approximately N and the Tropic of Capricorn in the southern hemisphere at S; these latitudes correspond to the axial tilt of the Earth...

Americas
The Americas, or America , are lands in the Western hemisphere, also known as the New World. In English, the plural form the Americas is often used to refer to the landmasses of North America and South America with their associated islands and regions, while the singular form America is primarily...

Tail
The tail is the section at the rear end of an animal's body; in general, the term refers to a distinct, flexible appendage to the torso. It is the part of the body that corresponds roughly to the sacrum and coccyx in mammals, reptiles, and birds...
