The fossils that were considered as Devonian insects, such as Rhyniognatha hirsti [17] or Strudiella devonica [18] were later reconsidered that their affinities as insects are insufficient. [ 3 ] [ 19 ] But based on phylogenic study, the first insects probably appeared earlier, in the Silurian period, [ 16 ] from stem-group crustaceans like ...
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.

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 ...
Of the 60 million European military personnel who were mobilised from 1914 to 1918, an estimated 8 million were killed, 7 million were permanently disabled, and 15 million were seriously injured. Germany lost 15.1% of its active male population, Austria-Hungary lost 17.1%, and France lost 10.5%. [ 247 ]
This list of wars by death toll includes all deaths directly or indirectly caused by the deadliest wars in history. These numbers encompass the deaths of military personnel resulting directly from battles or other wartime actions, as well as wartime or war-related civilian deaths, often caused by war-induced epidemics , famines , or genocides .
Mark Catesby publishes part one of The Natural History of Carolina, Florida and the Bahama Islands. 1734 Scientist René Antoine Ferchault de Réaumur publishes the first Mémoires pour Servir à L’Histoire des Insectes in English, "Memoirs Serving as a Natural History of Insects". This is a founding work of entomology, and one of the most ...
Globally, averages of these predictions estimate there are around 1.5 million beetle species and 5.5 million insect species, with around 1 million insect species currently found and described. [3] Between 950,000–1,000,000 of all described animal species are considered insects, so over 50% of all described eukaryotes (1.8 million species) are ...
While later Cold War-era allegations were propaganda, the idea of using the beetle for purposes of warfare had factual origins. During World War I, the French did actually draft plans for using the potato beetle against the Germans and in turn, during World War II, Germany worked on developing an insect army of its own, while simultaneously alleging that such a program was being carried out by ...
