Hyles Dahlii
''Hyles dahlii'' is a moth of the family Sphingidae first described by Carl Geyer in 1828. Distribution It is found on Corsica, Sardinia and the Balearic Islands. On rare occasions it is found on Sicily and along the north-eastern coast of Spain. It was introduced to Tunisia in the mid 1980s. On Menorca, the ''Hyles dahlii'' population consists of a hybrid with '' Hyles euphorbiae''. Due to this hybridisation, only few characteristics of ''Hyles dahlii'' are present in the imago. There is also hybridisation on Malta. Here it is a hybrid between ''Hyles dahlii'' and ''Hyles tithymali''. Research suggests that ''Hyles dahlii'' is in fact a species which evolved from ''Hyles tithymali'' through isolation. Description The wingspan is 65–85 mm.

Carl Geyer
Peter Carl Friedrich Geyer (1802–1889) was a German entomologist who wrote and illustrated various supplements to Jacob Hübner's works on Lepidoptera. Carl Geyer was by profession an artist. He is not to be confused with Karl Andreas Geyer (1809–1853), a botanist and plant collector. References *Evenhuis, N. L. 1997 ''Litteratura taxonomica dipterorum'' (1758–1930).

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Moths Described In 1827
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Euphorbia Pinea
''Euphorbia'' is a very large and diverse genus of flowering plants, commonly called spurge, in the family Euphorbiaceae. "Euphorbia" is sometimes used in ordinary English to collectively refer to all members of Euphorbiaceae (in deference to the type genus), not just to members of the genus. Euphorbias range from tiny annual plants to large and long-lived trees. The genus has roughly 2,000 members, making it one of the largest genera of flowering plants. It also has one of the largest ranges of chromosome counts, along with ''Rumex'' and '' Senecio''. '' Euphorbia antiquorum'' is the type species for the genus ''Euphorbia''. It was first described by Carl Linnaeus in 1753 in ''Species Plantarum''. Some euphorbias are widely available commercially, such as poinsettias at Christmas. Some are commonly cultivated as ornamentals, or collected and highly valued for the aesthetic appearance of their unique floral structures, such as the crown of thorns plant ('' Euphorbia m ...

Euphorbia Dendroides
''Euphorbia dendroides'', also known as tree spurge, is a small tree or large shrub of the family Euphorbiaceae that grows in semi-arid and mediterranean climates. Distribution and habitat ''Euphorbia dendroides'' has a wide distribution throughout the Mediterranean Sea, from the Balearic Islands in the west to the Aegean Islands in the east. It is found primarily in Europe and is restricted to northern Tunisia in North Africa. This plant is sensitive to frost, so it only grows on protected and sunny mountainsides in hilly areas. It has been introduced to other countries out of its original range as an ornamental tree. Description This bush also has uses in Complementary and alternative medicine, traditional medicine; like many other species of genus ''Euphorbia'' its toxic white and sticky sap has been used to treat skin excrescences, like cancers, tumors, and warts since ancient times.

Euphorbia Paralias
''Euphorbia paralias'', the sea spurge, is a species of flowering plant in the family Euphorbiaceae, native to Europe, northern Africa and western Asia. The species is widely naturalised in Australia. It invades coastal areas, displacing local species and colonising open sand areas favoured by certain nesting birds. Major eradication programmes have been undertaken in some areas, for example by Sea Spurge Remote Area Teams in Tasmania, with great success. Description It is an erect, glaucous, perennial plant growing up to 70 cm tall. The plant has many stems, dividing into 3-5 fertile branches, each branching further. The cauline leaves (arising from the stem, without stalk) are crowded, overlapping, elliptic-ovate (ovate toward the top of the stems), fleshy and 5 to 20 mm long.

Hyles Tithymali
''Hyles tithymali'', the Barbary spurge hawk-moth, is a moth of the family Sphingidae first described by Jean Baptiste Boisduval in 1834. It is found in North Africa, the Canary Islands, Madeira, some islands in the Mediterranean Sea and in the mountains in Yemen. The length of the forewings is 45–85 mm. The larvae feed on ''Euphorbia''. It is thought that ''Hyles tithymali'' had a much larger range in Europe, but has been pushed further south after the cooling 3600 years ago. Its place has been taken over by ''Hyles euphorbiae ''Hyles euphorbiae'', the spurge hawk-moth, is a European moth of the family Sphingidae. This hawk moth is used as an agent of biological pest control against the noxious weed leafy spurge (''Euphorbia virgata''), but usually only in conjunction ...'', which is more resistant to the cold. Because of this, many isolated populations exist today, many of which have developed into distinct subspecies. Subspecies The following subspecies are rec ...
