Hydrorybina violascens is a moth in the family Crambidae. It was described by George Hampson in 1917. It is found on Borneo. [1]
Moths comprise a group of insects related to butterflies, belonging to the order Lepidoptera. Most lepidopterans are moths, and 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.
The Crambidae are the grass moth family of lepidopterans. They are variable in appearance, the nominal subfamily Crambinae taking up closely folded postures on grass stems where they are inconspicuous, while other subfamilies include brightly coloured and patterned insects which rest in wing-spread attitudes.
Sir George Francis Hampson, 10th Baronet was a British entomologist.
The wingspan is about 16 mm. The forewings are cupreous-red brown with a purplish gloss. There is an oblique dark brown antemedial line and a dark discoidal bar. The postmedial line is black brown and the termen is black brown with a silvery gloss. The hindwings are cupreous-red brown with a purplish gloss. The costal area is whitish with some dark irroration (speckling) below the end of the cell, as well as a black postmedial line. [2]
The wingspan 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 60.93 metres, and a wandering albatross caught in 1965 had a wingspan of 3.63 metres, 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 fixed-wing 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 to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stands at 7 ft 7 in (2.31 m) and owns one of the largest wingspans at 8 ft 6 in (2.59 m).
