Pycnarmon leucinodialis is a moth in the family Crambidae described by William Schaus in 1912. It is found in Costa Rica. [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.
William Schaus was an American entomologist who became known for his major contribution to the knowledge and description of new species of the Neotropical Lepidoptera.
The wingspan is about 21 mm. The wings are semihyaline iridescent white, the forewings have a more thickly scaled costal margin. There is a brownish streak on the costa towards base and two short streaks in the cell below it, as well as a white line on the discocellular, edged with pale brown. The outer line is fuscous and broad and the marginal area is shaded with light brown, except on the costa at the apex. The hindwings have a brownish shade on the discocellular, followed by some dark points. There is a subterminal fuscous line, which is more heavily marked on the costa and inner margin. The termen is more heavily scaled and silvery white. [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).
A hyaline substance is one with a glassy appearance. The word is derived from Greek: ὑάλινος transparent and Greek: ὕαλος crystal, glass.
