List of endangered insects

In July 2017, the International Union for Conservation of Nature (IUCN) listed 343 endangered insect species.[1] Of all evaluated insect species, 5.7% are listed as endangered. The IUCN also lists 21 insect subspecies as endangered.

  • 5993 extant species have been evaluated
  • 4291 of those are fully assessed[a]

  • 1146 to 2848 are threatened[c]
  • 59 to 105 are extinct or extinct in the wild:
    • 58 extinct (EX) species[d]
    • 1 extinct in the wild (EW)

Endangered (EN) species are considered to be facing a very high risk of extinction inside.

No subpopulations of insects 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 insects are listed separately. There are 538 insect species which are endangered or critically endangered.

Additionally 1702 insect species (28% 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]
