Herbert Womersley
Herbert Womersley (1889–1962) was an entomologist whose works were especially concerned with mites and ticks, silverfish and flies. His research into the diversity of Australian resulted in descriptions of new insect taxa. Biography Womersley was enlisted for wartime service in two English military sections, during 1915 to 1917 in the Royal Army Medical Corps and the Chemical Corps, Royal Engineers. After volunteering to join the chemical engineers, Womersley was engaged to transport tanks of poisons toward the frontlines of battle and release phosgene, chlorine and other weaponised gases when the prevailing wind became unfavourable to the enemy. Womersley was involved in the earliest chemical weapon attacks on German troops during the European conflict, including the first British use at the Battle of Loos. He served next at the munitions factory, H.M. Factory Gretna as a chemist until the end of the war. His later employment in Britain included a soap manufacturer and p ...

Warrington
Warrington () is a town and unparished area in the Borough of Warrington, borough of the same name in the ceremonial county of Cheshire, England, on the banks of the River Mersey. It is east of Liverpool, and west of Manchester. The population in 2019 was estimated at 165,456 for the town's urban area, and just over 210,014 for the entire borough, the latter being more than double that of 1968 when it became a New towns in the United Kingdom, new town. Warrington is the largest town in the ceremonial county of Cheshire. In 2011 the unparished area had a population of 58,871. Warrington was founded by the Roman Empire, Romans at an important crossing place on the River Mersey. A new settlement was established by the Saxons, Saxon Wærings. By the Middle Ages, Warrington had emerged as a market town at the lowest bridging point of the river. A local tradition of textile and tool production dates from this time. The town of Warrington (north of the Mersey) is within the bounda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apterygota
The name Apterygota is sometimes applied to a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history; notable examples are the silverfish, the firebrat, and the jumping bristletails. Their first known occurrence in the fossil record is during the Devonian period, 417–354 million years ago. The group Apterygota is not a clade; it is paraphyletic, and not universally recognized. As defined, the group contains two separate clades of wingless insects: Archaeognatha comprises jumping bristletails, while Zygentoma comprises silverfish and firebrats. The Zygentoma are in the clade Dicondylia with winged insects, a clade that includes all other insects, while Archaeognatha is sister to this lineage.A. Blanke, M. Koch, B. Wipfler, F. Wilde, B.

1962 Deaths
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Collembola
Springtails (Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects (the other two are the Protura and Diplura). Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts. Collembolans are omnivorous, free-living organisms that prefer moist conditions. They do not directly engage in the decomposition of organic matter, but contribute to it indirectly through the fragmentation of organic matter and the control of soil microbial communities. The word ''Collembola'' is from the ancient Greek "glue" and "peg"; this name was given due to the existence of the collophore, which was previously thought to stick to surfaces to stabilize the creature. Some DNA sequence studies suggest that Collembola represent a separate evolutionary line ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
