Arthropod species (IUCN, 2015.4)
  • 9018 species have been evaluated
  • 6285 are fully assessed (excludes DD)
  • 4222 are not threatened at present (LC, NT, LR/cd)
  • 1980 are threatened (CR, EN, VU)
  • 83 to 162 are extinct or extinct in the wild (EX, EW, CR(PE), CR(PEW))
Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

As of February 2016, the International Union for Conservation of Nature (IUCN) lists 1031 vulnerable arthropod species.[1] 11% of all evaluated arthropod species are listed as vulnerable. The IUCN also lists 29 arthropod subspecies as vulnerable.

No subpopulations of arthropods have been evaluated by the IUCN.

For a species to be assessed as vulnerable to extinction, the best available evidence must meet quantitative criteria set by the IUCN designed to reflect "a high risk of extinction in the wild". Endangered and critically endangered species face an even higher risk, and are listed separately: List of critically endangered arthropods, List of endangered arthropods, even though they also meet the quantitative criteria for vulnerable species. The three categories combined are referred to as threatened species.

Additionally 2733 arthropod species (30% of those evaluated) 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.[2] 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."[3]
