- Insects contain more than one million described species and are the largest community of animals; they constitute over half of all recognized organisms. The overall number of animals currently in nature is estimated at six to ten million; over 90 percent of the world's animal life types are probably insects. Insects can be found in almost any area, but there are only a restricted number of species in the oceans.
- The phytophagous insects are feeding on green plants. Species, including large, adult or larvae are targeting roots, branches, leaves, flowers and fruits. There are many phytophagous insects and the total number of species is at least 500,000. This is about 25% of known multicellular organisms.
- The majority of insect orders contain phytophagous insect species, including Orthoptera, Lepidoptera, Coleoptera, Heteroptera, Hymenoptera and Diptera; however, there are great variations among different classes in the number of species.
