| Eupselia tristephana Meyrick, 1915 | |
Eupselia tristephana is a moth in the family Depressariidae. It was described by Edward Meyrick in 1915. It is found in Australia, where it has been recorded from Western Australia, the Northern Territory and Queensland. [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.
Depressariidae is a family of moths. It has formerly been treated as a subfamily of Gelechiidae, but is now recognised as a separate family, comprising about 2300 species worldwide.
Edward Meyrick FRS was an English schoolmaster and amateur entomologist. He was an expert on Microlepidoptera and some consider him one of the founders of modern Microlepidoptera systematics.
The wingspan is 12–13 mm. The forewings are dark bronzy fuscous with an erect triangular light ochreous-yellow blotch from the dorsum before the middle, its apex rather bent over posteriorly. There are three bright coppery-blue-purple transverse lines reaching from the dorsum three-fourths across the wing, the first immediately beyond the yellow blotch, the second connected with a light yellow spot on the costa beyond the middle, the third limiting an oval bronzy patch strewn with minute longitudinal blackish and rosy-whitish strigulae extending along the termen nearly to the costa. There is a narrow black streak along the lower half of the termen containing three small round black spots set in whitish-ochreous rings becoming golden metallic on the terminal edge. Two short oblique blue-purple marks are found before the apex. The hindwings are dark fuscous. [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).
