Alternatively, the bee may come into contact with an insecticide and transport it back to the colony in contaminated pollen or nectar or on its body, potentially causing widespread colony death. [3] Actual damage to bee populations is a function of toxicity and exposure of the compound, in combination with the mode of application.
The Permian–Triassic extinction event saw the greatest level of insect extinction, and the Cretaceous–Paleogene the second highest. Insect diversity has recovered after mass extinctions, as a result of periods in which new species originate with increased frequency, although the recovery can take millions of years.
Up to 2 million plant and animal species worldwide are in danger of extinction, a new analysis suggests.. The International Union for Conservation of Nature's Red List reports that 19% of European ...
For a species to be considered endangered by the IUCN it must meet certain quantitative criteria which are designed to classify taxa facing "a very high risk of extinction". An even higher risk is faced by critically endangered species, which meet the quantitative criteria for endangered species. Critically endangered insects are listed ...
Perdita meconis, the Mojave poppy bee, is a rare bee species that was described in 1993. [2] The Mojave poppy bee has been petitioned for protection under the Endangered Species Act due to pressures in their native range such as invasive species, habitat fragmentation, gypsum mining, and climate change.

Vaquitas are not being hunted to extinction, but they are suffering collateral damage from fishing. The small porpoises get caught in fishing nets, called gillnets, meant to catch the endangered ...
