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.
The females deposit their eggs in male-guarded crevices between rocks. Eggs are 4 by 2.2 mm (0.16 by 0.087 in) in size, while egg clutches can contain up to five thousand eggs. Males are territorial and will defend eggs from predators as well as continuously fan them to provide the developing embryos with oxygenated water.
Since a fertilized egg represents a complete organism at one stage of its life cycle, eating an egg is a form of predation, the killing of another organism for food. Egg predation is found widely across the animal kingdom, including in fish, birds, snakes, mammals, and arthropods. Some species are specialist egg predators, but many more are ...
Nudibranchs typically deposit their eggs within a gelatinous spiral, [35] which is often described as looking like a ribbon. The number of eggs varies; it can be as few as just 1 or 2 eggs (Vayssierea felis) or as many as an estimated 25 million (Aplysia fasciata [36]). The eggs contain toxins from sea sponges as a means of deterring predators ...
Viburnum lesquereuxii leaf with insect damage; Dakota Sandstone (Cretaceous) of Ellsworth County, Kansas. Scale bar is 10 mm. Knowledge of herbivory in geological time comes from three sources: fossilized plants, which may preserve evidence of defense (such as spines) or herbivory-related damage; the observation of plant debris in fossilised animal feces; and the structure of herbivore mouthparts.
Like the eggs of other Uraniidae, the sunset moth's eggs are domed with projecting ribs. [25] A single egg weighs about 1 milligram (3.5 × 10 −5 oz) and usually has 17 ribs, but sometimes 18 or less often 16. The eggs are usually laid on the lower surface of Omphalea leaves, but occasionally on the upper surface. Eggs are laid in groups of ...
