See: List of endangered insects, List of critically endangered insects. Vulnerable, endangered and critically endangered species are collectively referred to as threatened species 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 ...
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.
The digestive system is typical of insects, with Malpighian tubules discharging into the midgut. Carbohydrates are digested mainly in the crop, while proteins are digested in the ceca of the midgut. Saliva is abundant but largely free of enzymes, helping to move food and Malpighian secretions along the gut.
43 termite species are used as food by humans or are fed to livestock. [254] These insects are particularly important in impoverished countries where malnutrition is common, as the protein from termites can help improve the human diet. Termites are consumed in many regions globally, but this practice has only become popular in developed nations ...
Between 950,000–1,000,000 of all described animal species are considered insects, so over 50% of all described eukaryotes (1.8 million species) are insects (see illustration). With only 950,000 known non-insects, if the actual total number of insects is 5.5 million, they may represent over 80% of the total, and with only about 20,000 new ...
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.
