The first insects were landbound, but about 400 million years ago in the Devonian period one lineage of insects evolved flight, the first animals to do so. [1] The oldest insect fossil has been proposed to be Rhyniognatha hirsti , estimated to be 400 million years old, but the insect identity of the fossil has been contested. [ 3 ]
Many insects are ecologically beneficial as predators of pest insects, while a few provide direct economic benefit. Two species in particular are economically important and were domesticated many centuries ago: silkworms for silk and honey bees for honey. Insects are consumed as food in 80% of the world's nations, by people in roughly 3,000 ...
Entomological warfare is not a new concept; historians and writers have studied EW in connection to multiple historic events. A 14th-century plague epidemic in Asia Minor that eventually became known as the Black Death (carried by fleas) is one such event that has drawn attention from historians as a possible early incident of entomological warfare.

There has also been a history of people becoming entomologists through museum curation and research assistance, [11] such as Sophie Lutterlough at the Smithsonian National Museum of Natural History. Insect identification is an increasingly common hobby, with butterflies [12] and (to a lesser extent) dragonflies being the most popular. [13]
Biological weapons were used against Chinese soldiers and civilians in several military campaigns. [43] In 1940, the Japanese Army Air Force bombed Ningbo with ceramic bombs full of fleas carrying the bubonic plague. [44] Many of these operations were ineffective due to inefficient delivery systems, [42] although up to 400,000 people may have ...
For example, cats and dogs were kept by soldiers in the trenches to "help maintain hygiene" by culling the rodent population. [12] Terrier dogs were especially useful, more so than cats, as they were bred to kill vermin and for hunting purposes which was applied to eliminating rats in the trenches. [13] As such, many terriers were used as ...
Before World War II, the events of 1914–1918 were generally known as the Great War or simply the World War. [1] In August 1914, the magazine The Independent wrote "This is the Great War. It names itself". [2] In October 1914, the Canadian magazine Maclean's similarly wrote, "Some wars name themselves. This is the Great War."
Almost as soon as they were invented, planes were drafted for military service. Battles: 1914 in aviation.
