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 ...
Plants evolved chemical defenses against this herbivory and the insects in turn evolved mechanisms to deal with plant toxins. [5] These toxins limit the diet breadth of herbivores, and evolving mechanisms to nonetheless continue herbivory is an important part of maintaining diet breadth in insects, and so in their evolutionary history as a whole.

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.
Insect biodiversity accounts for a large proportion of all biodiversity on the planet—over half of the estimated 1.5 million organism species described are classified as insects. [ 1 ] [ 2 ] A pie chart of described eukaryote species, showing just over half of these to be insects
Insectary plants are those that attract insects. As such, beneficial insectary plants are intentionally introduced into an ecosystem to increase pollen and nectar resources required by the natural enemies of the harmful or unwanted insects pests. Beyond an effective natural control of pests, the beneficial insects also assist in pollination.
The true bugs, Hemiptera, have piercing and sucking mouthparts and live by sucking sap from plants. These include aphids, whiteflies and scale insects. Apart from weakening the plant, they encourage the growth of sooty mould on the honeydew the insects produce, which cuts out the light and reduces photosynthesis, stunting the plant's growth ...
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
