List of vulnerable arthropods

In July 2016, the International Union for Conservation of Nature (IUCN) listed 1080 vulnerable arthropod species.[1] Of all evaluated arthropod species, 11% are listed as vulnerable. The IUCN also lists 29 arthropod subspecies as vulnerable.

2 extinct in the wild arthropod species (0.02%)393 critically endangered arthropod species (4.1%)626 endangered arthropod species (6.6%)1081 vulnerable arthropod species (11%)398 near threatened arthropod species (4.2%)4080 least concern arthropod species (43%)2890 data deficient arthropod species (31%)
Arthropod species (IUCN, 2016-2)
  • 9470 extant species have been evaluated
  • 6580 of those are fully assessed[a]
  • 4478 are not threatened at present[b]
  • 2100 to 4990 are threatened[c]
  • 83 to 169 are extinct or extinct in the wild:
    • 81 extinct (EX) species[d]
    • 2 extinct in the wild (EW)
    • 86 possibly extinct [CR(PE)]
    • 0 possibly extinct in the wild [CR(PEW)]

Vulnerable (VU) species are considered to be facing a high risk of extinction in the wild.

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 also meet the quantitative criteria of vulnerable species, and are listed separately. See: List of endangered arthropods, List of critically endangered arthropods. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species by the IUCN.

Additionally 2875 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]
