The species name of the orange-barred sulfur is philea. how should the name be scientifically written?

The system of scientific naming or nomenclature is use to identify an organisms worldwide. The system of naming of an organism is introduced by Carolus Linnaeus. The scientific name of any organism is written by its genus name and species name. This is called binomial system of naming. While writing the scientific name of an organism, the name of the genus written first with a capital letter and the name of the species is written second with a small letter.  When typed scientific name is in italics and when it is hand written the genus name and the species are to be underlined separately.  

In the given example, the scientific name of orange-barred sulfur butterfly is Phoebis philea. Phoebis is its genus name and philea is the species name.

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
