An upper pitcher of Nepenthes lowii, a tropical pitcher plant that supplements its carnivorous diet with tree shrew droppings. [1] [2] [3]Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds.
The secretory system can only function a single time, so that a particular area of the leaf surface can only be used to digest insects once. [4] Unlike many other carnivorous plant species, butterworts do not appear to use jasmonates as a control system to switch on the production of digestive enzymes. Jasmonates are involved in the butterwort ...
Many pitcher plants exhibit patterns of ultraviolet coloration which may play a role in attracting insects. [3] Some species, such as Cephalotus follicularis , likely use camouflage to trap insects, as their coloration matches that of the surrounding environment and the plants are often embedded in the substrate such that the traps are flush ...

The coating of plants with honeydew can contribute to the spread of fungi which can damage plants. [118] [119] Honeydew produced by aphids has been observed to reduce the effectiveness of fungicides as well. [120] A hypothesis that insect feeding may improve plant fitness was floated in the mid-1970s by Owen and Wiegert.
Drosera, which is commonly known as the sundews, is one of the largest genera of carnivorous plants, with at least 194 species. [2] These members of the family Droseraceae [1] lure, capture, and digest insects using stalked mucilaginous glands covering their leaf surfaces. The insects are used to supplement the poor mineral nutrition of the ...

[1] An alternative term is entomophage, [2] which can also refer to the human practice of eating insects. The first vertebrate insectivores were amphibians.
