Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Kleiber's law describes the relationship between an animal's size and its feeding strategy, saying that larger animals need to eat less food per unit weight than smaller animals. [21] Kleiber's law states that the metabolic rate (q 0) of an animal is the mass of the animal (M) raised to the 3/4 power: q 0 =M 3/4
In zoology, a florivore (not to be confused with a folivore) is an animal which mainly eats products of flowers.Florivores are types of herbivores (often referred to as floral herbivores), yet within the feeding behaviour of florivory, there are a range of other more specific feeding behaviours, including, but not limited to: [1]
A Bornean orangutan (Pongo pygmaeus) eating a fruit. A frugivore (/ f r uː dʒ ɪ v ɔːr /) is an animal that thrives mostly on raw fruits or succulent fruit-like produce of plants such as roots, shoots, nuts and seeds. Approximately 20% of mammalian herbivores eat fruit. [1]
Food items include fruit, flowers, nectar, and leaves. [ 53 ] [ 54 ] They will sometimes deliberately consume insects such as cicadas as well. [ 55 ] In Australia, eucalypt blossoms and pollen are preferred food sources, followed by Melaleuca and Banksia flowers [ 56 ] They feed on a wide variety of crops as well, causing conflicts with farmers.
The larvae primarily feed in groups; they are folivores, eating plants and fruits on native trees and shrubs, though some are parasitic. [5] [46] [47] However, this is not always the case; Monterey pine sawfly larvae are solitary web-spinners that feed on Monterey pine trees inside a silken web. [48] The adults feed on pollen and nectar. [46]
This small marsupial has a compact body and distinctive reddish-brown fur that helps it blend into its tropical surroundings. It has a shy personality, and feeds on leaves, fruits, and flowers ...
The Indian flying fox is frugivorous or nectarivorous: it eats fruits and blossoms, and it drinks nectar from flowers. [32] At dusk, it forages for ripe fruit. It is a primarily generalist feeder, and eats any available fruits. Seeds from ingested fruits are scarified in its digestive tract and dispersed through its waste. [31]
