Teacher: Now, understand the problem? Solve this instance: Context: Phyllophaga is a very large genus ( more than 260 species ) of New World scarab beetles in the subfamily Melolonthinae . Common names for this genus and many other related genera in the subfamily Melolonthinae are May beetles , June bugs , and June beetles . They range in size from 12 to 35 mm ( 0.47 to 1.38 in ) and are blackish or reddish - brown in colour , without prominent markings , and often rather hairy ventrally . These beetles are nocturnal , coming to lights in great numbers . The generic name is derived from the Greek words phyllon (  ) , which means `` leaf '' , and phagos (  ) , which means `` eater '' , with a plural ending ., Beetles are a group of insects that form the order Coleoptera. The word "coleoptera" is from the Greek , "koleós", meaning "sheath"; and , "pterón", meaning "wing", thus "sheathed wing", because most beetles have two pairs of wings, the front pair, the "elytra", being hardened and thickened into a shell-like protection for the rear pair and the beetle's abdomen. The order contains more species than any other order, constituting almost 25% of all known animal life-forms. About 40% of all described insect species are beetles (about 400,000 species), and new species are discovered frequently. The largest taxonomic family, the Curculionidae (the weevils or snout beetles), also belongs to this order., In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., Melolonthinae is a subfamily of the scarab beetles (family Scarabaeidae). It is a very diverse group; distributed over most of the world, it contains many familiar species. Some authors include the scarab subfamilies Euchirinae and Pachypodinae as tribes in the Melolonthinae., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Euchirinae is a subfamily of Scarabaeidae or scarab beetles in the superfamily Scarabaeoidea. They are sometimes referred to as "long-armed scarabs" due to the elongated forelegs of the males. These long legs often have median and apical spines that are fixed in the male while females have a movable terminal spine., Subject: phyllophaga, Relation: parent_taxon, Options: (A) animal (B) coleoptera (C) homo (D) insects (E) melolonthinae (F) scarabaeidae (G) scarabaeoidea
