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 ...

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 ...
Tomato plants can be toxic to dogs if they eat large amounts of the fruit or chew the plant material. [38] Solanum tuberosum: potato: Solanaceae: Potatoes contain toxic glycoalkaloids, of which the most prevalent are solanine and chaconine.
Pollination is necessary for plants to continue their populations and 3/4 of the plant species that contribute to the world's food supply are plants that require pollinators. [78] Insect pollinators, like bees, are large contributors to crop production, over 200 billion dollars worth of crop species are pollinated by these insects. [71]
Hoverflies, also called flower flies or syrphids, make up the insect family Syrphidae. As their common name suggests, they are often seen hovering or nectaring at flowers ; the adults of many species feed mainly on nectar and pollen , while the larvae ( maggots ) eat a wide range of foods.
Their flowers tend to be small and inconspicuous with many pollen grains and large, feathery stigmas to catch the pollen. However, this is relatively uncommon (only 2% of pollination is hydrophily) and most aquatic plants are insect-pollinated, with flowers that emerge into the air. Vallisneria is an example.

Certain caterpillars eat plants that are toxic to both themselves and the parasite to cure themselves. [24] Drosophila melanogaster larvae also self-medicate with ethanol to treat parasitism. [25] D. melanogaster females lay their eggs in food containing toxic amounts of alcohol if they detect parasitoid wasps nearby. The alcohol protects them ...
