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.
Hypericum / ˌ h aɪ ˈ p iː r ɪ k əm / is a genus of flowering plants in the family Hypericaceae (formerly considered a subfamily of Clusiaceae). [3] [4] The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. [5] Many Hypericum species are regarded as invasive species and noxious weeds.
Some plants (or select parts) require cooking to make them safe for consumption. Field guides instruct foragers to carefully identify species before assuming that any wild plant is edible. Accurate determination ensures edibility and safeguards against potentially fatal poisoning .
