Thudaca heterastis is a moth in the Depressariidae family. It was described by Edward Meyrick in 1893. It is found in Australia, where it has been recorded from Western Australia. [1]

Moth Group of mostly-nocturnal insects in the order Lepidoptera

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 16–20 mm. The forewings are snow white with a moderate orange streak immediately beneath the costa from the base to the costa near the apex, sometimes obsolete beyond two-thirds. There is a rather broad orange streak along the inner margin to the anal angle, becoming suddenly subdorsal on the basal fourth and not quite reaching the base, usually more or less wholly suffused with dark fuscous, posteriorly attenuated. There is a transverse orange streak suffused with dark fuscous, from the subcostal streak at three-fifths to the middle of the dorsal streak, forming an obtuse-angled zigzag in the middle, sometimes interrupted or wholly absent. A straight orange streak, suffused with dark fuscous, is found from the costa near the apex to the anal angle, sometimes widely interrupted or visible at the extremities only. There are some dark fuscous scales on the hindmargin. The hindwings are pale whitish grey, faintly yellowish tinged. [2]

Wingspan distance from one wingtip to the other wingtip of an airplane or an animal (insect, bird, bat)

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).
