Critically Endangered (CR) species face an extremely high risk of extinction in the wild.

As of July 2016, the International Union for Conservation of Nature (IUCN) lists 195 critically endangered insect species, including 46 which are tagged as possibly extinct.[1][2] 3.2% of all evaluated insect species are listed as critically endangered. The IUCN also lists two insect subspecies as critically endangered.

No subpopulations of insects have been evaluated by the IUCN.

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.[3] 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."[4]

This is a complete list of critically endangered insect species and subspecies as evaluated by the IUCN. Species considered possibly extinct by the IUCN are marked as such.
