Megoura Viciae
''Megoura viciae '' is a large, green aphid in the family Aphididae native to Europe that feeds on plants in the genus '' Vicia''. They are commonly known as vetch aphids for this reason. Taxonomy ''Megoura viciae'' was described by English entomologist George Bowdler Buckton in 1876. It is the type species of the genus ''Megoura''. Morphology ''Megoura viciae'' has a large globular green abdomen with a smaller black prothorax, black cauda, black legs, black antennae and a black head. Towards the rear of the body are large crescent-shaped black sclerites which are in front of the siphunculi. The eyes are red in colour. Dependent on the stage in their lifecycle ''M. viciae '' may be winged or wingless. Distribution and habitat ''Megoura viciae '' is widely present in Europe, from latitudes 64–65° N across Scandinavia, into Denmark and the rest of Europe (including England) and south to the Mediterranean. It also occurs in Ethiopia and has been recorded from North Amer ...

Aphid
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ...

Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Arthropod
Arthropods (, (gen. ποδός)) are invertebrate animals with an exoskeleton, a Segmentation (biology), segmented body, and paired jointed appendages. Arthropods form the phylum Arthropoda. They are distinguished by their jointed limbs and Arthropod cuticle, cuticle made of chitin, often Mineralization (biology), mineralised with calcium carbonate. The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an exoskeleton, external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings. They are an extremely diverse group, with up to 10 million species. The haemocoel, an arthropod's internal cavity, through which its haemolymph – analogue of blood – circulates, accommodates its interior Organ (anatomy), organs; it has an open circulatory system. Like their exteriors, the internal or ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ...

Hemiptera
Hemiptera (; ) is an order (biology), order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, Reduviidae, assassin bugs, Cimex, bed bugs, and shield bugs. They range in size from to around , and share a common arrangement of piercing-sucking Insect mouthparts, mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Entomologists reserve the term ''bug'' for Hemiptera or Heteroptera,Gilbert Waldbauer. ''The Handy Bug Answer Book.''

Aphididae
The Aphididae are a very large insect family in the aphid superfamily ( Aphidoidea), of the order Hemiptera. These insects suck the sap from plant leaves. Several thousand species are placed in this family, many of which are considered plant/crop pests. They are the family of insects containing most plant virus vectors (around 200 known) with the green peach aphid (''Myzus persicae'') being one of the most prevalent and indiscriminate carriers. Evolution Aphids originated in the late Cretaceous about (Mya), but the Aphidinae which comprises about half of the 4700 described species and genera of aphids alive today come from their most recent radiation which occurred in the late Tertiary less than 10 Mya.Von Dohlen CD, Moran NA (2000) Molecular data support a rapid radiation of aphids in the Cretaceous and multiple origins of host alternation.

Aphidinae
Aphidinae is an aphid subfamily in the family Aphididae. Many species In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate s ... of aphids spread potyviruses and most are from the subfamily Aphidinae (genera '' Macrosiphum'' and '' Myzus''). Most have alternative hosts, the primary host plant is usually a tree, and the secondary one is herbaceous.

George Bowdler Buckton
George Bowdler Buckton (24 May 1818, London – 25 September 1905, Haslemere, Surrey) was an English chemist and entomologist who specialised in aphids. Early Life Buckton was born in London and lived in Hornsey, England. He was the eldest son of George Buckton (1785 - 1847; Proctor to the Prerogative Court of Canterbury) and Eliza Buckton (née Merricks, 1786 - 1842). At the age of five he had an accident which left him partially paralysed for the rest of his long life; this precluded attendance at school so he was privately educated. He became however a scholar of classics and was an accomplished musician and painter. After his father's death he moved to Queen's Road, West London, and In 1848 he became an assistant to August Wilhelm von Hofmann (1818-1892) at the nearby Royal College of Chemistry in London. /sup> In 1867 he married Mary Ann Odling (1831 – 1927), the sister of William Odling with whom he had written his last chemical paper. He designed his house at Hasl ...
