Alesa Thelydrias
''Alesa'' is a New World (Neotropical realm) genus of metalmark butterflies found in northern South America. This genus is distinguished by a vast sexual dimorphism receding somewhat only in one species. The body is slender, the head is broad and slanting, with a flat forehead and closely appressed (flattened) short palpi. The antennae are very long, only slightly thickened at their ends. The abdomen is long, in the male thin, in the female stout, but likewise stretched. The forewings are long with a very oblique distal margin. The hindwings are round, especially in the female. Cells of all the wings closed, the upper radial originates with the 3rd subcostal vein from the same place. Colouring of the females is earthy brown, that of the males varying, but with a metallic lustre.

Edward Doubleday
Edward Doubleday (9 October 1810 – 14 December 1849) was an English entomologist primarily interested in Lepidoptera. He is best known for ''The Genera of Diurnal Lepidoptera: Comprising Their Generic Characters, a Notice of Their Habits and Transformations, and a Catalogue of the Species of Each Genus'', co-written with John O. Westwood, and illustrated by William Chapman Hewitson; and ''List of the Specimens of Lepidopterous Insects in the Collection of the British Museum''. Doubleday was born on 9 October 1810 in Epping, Essex, the second son of Benjamin and Mary Doubleday. His older brother was Henry Doubleday who also grew up to become a notable entomologist. They were both interested in natural history and spent their childhood collecting specimens in the nearby Epping Forest. The boys grew up in a Quaker family and Edward received a good classical education at the local Quaker school. In 1835, he joined a fellow Quaker named Robert Foster on a trip to the United State ...

Riodinidae Of South America
Riodinidae is the family of metalmark butterflies. The common name "metalmarks" refers to the small, metallic-looking spots commonly found on their wings. The 1532 species are placed in 146 genera. Although mostly Neotropical in distribution, the family is also represented both in the Nearctic, Palearctic, Australasian ('' Dicallaneura''), Afrotropic ('' Afriodinia'', ''Saribia''), and Indomalayan realms. Description The family includes small to medium-sized species, from 12 to 60 mm wingspan, often with vibrant structural colouring. The wing shape is very different within the family. They may resemble butterflies in other groups, some are similar to Satyrinae, some are bright yellow reminiscent of Coliadinae and others (examples ''Barbicornis'', ''Rhetus arcius'', ''Helicopis'', ''Chorinea'') have tails as do Papilionidae. The colouration ranges from muted colours in the temperate zone species to iridescent blue and green wings and transparent wings in tropical s ...

Drop (liquid)
A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the lower end of a tube or other surface boundary, producing a hanging drop called a pendant drop. Drops may also be formed by the condensation of a vapor or by atomizer nozzle, atomization of a larger mass of solid. Water vapor will condense into droplets depending on the temperature. The temperature at which droplets form is called the dew point. Surface tension Liquid forms drops because it exhibits surface tension. A simple way to form a drop is to allow liquid to flow slowly from the lower end of a vertical tube of small diameter. The surface tension of the liquid causes the liquid to hang from the tube, forming a pendant. When the drop exceeds a certain size it is no longer stable and detaches itself. The falling liquid is also a drop held together by surface tension. Viscosity and pitch drop experiments Some substa ...
