Pollination of flowering plants by insects including bees, butterflies, flies, and beetles, is economically important. [162] The value of insect pollination of crops and fruit trees was estimated in 2021 to be about $34 billion in the US alone. [163] Insects produce useful substances such as honey, [164] wax, [165] [166] lacquer [167] and silk ...
Most commonly, flowers are insect-pollinated, known as entomophilous; literally "insect-loving" in Greek. [61] To attract these insects flowers commonly have glands called nectaries on various parts that attract animals looking for nutritious nectar. [62] Some flowers have glands called elaiophores, which produce oils rather than nectar. [63]
Forensic entomology is a branch of forensic science that studies insects found on corpses or elsewhere around crime scenes. This includes studying the types of insects commonly found on cadavers, their life cycles, their presence in different environments, and how insect assemblages change with decomposition. [16]
Plants fall into pollination syndromes that reflect the type of pollinator being attracted. These are characteristics such as: overall flower size, the depth and width of the corolla, the color (including patterns called nectar guides that are visible only in ultraviolet light), the scent, amount of nectar, composition of nectar, etc. [2] For example, birds visit red flowers with long, narrow ...
Self-pollination occurs when pollen from one flower pollinates the same flower or other flowers of the same individual. [45] It is thought to have evolved under conditions when pollinators were not reliable vectors for pollen transport, and is most often seen in short-lived annual species and plants that colonize new locations.

Dung beetles (Scarabaeus laticollis) and dung ballDecomposer insects are those that feed on dead or rotten bodies of plants or animals. These insects are called saprophages [12] and fall into three main categories: those that feed on dead or dying plant matter, those that feed on dead animals (carrion), and those that feed on excrement (feces) of other animals.
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar ; they may also ...
Mouthparts can have multiple functions. Some insects combine piercing parts along with sponging ones which are then used to pierce through tissues of plants and animals. Female mosquitoes feed on blood (hemophagous) making them disease vectors. The mosquito mouthparts consist of the proboscis, paired mandibles and maxillae.
