List of endangered arthropods


In July 2016, the International Union for Conservation of Nature listed 616 endangered arthropod species. Of all evaluated arthropod, 6.5% species are listed as endangered.
The IUCN also lists 27 arthropod subspecies as endangered.
No subpopulations of arthropods have been evaluated by the IUCN.
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 arthropods are listed separately. There are 1010 arthropod species which are endangered or critically endangered.
Additionally 2875 arthropod species are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. While the category of data deficient indicates that no assessment of extinction risk has been made for the taxa, the IUCN notes that it may be appropriate to give them "the same degree of attention as threatened taxa, at least until their status can be assessed".
This is a complete list of endangered arthropod species and subspecies as evaluated by the IUCN.
