Entomophily is a form of pollination whereby pollen or spores are distributed by insects.
Several insects are reported to be responsible for the pollination (potential or effective)
of many plant species, particularly bees, Lepidoptera (for example; butterflies and
moths), wasps, flies, ants and beetles. Some plant species co-evolved with a particular
pollinator, such as many orchids species. On the other hand, there are plant species
which are generalists, being visited and/or pollinated by several insect groups. Entomophilous
species frequently evolve mechanisms to make themselves more appealing to insects, for
example; brightly colored or scented flowers, nectar, or appealing shapes and patterns.
Pollen grains of entomophilous plants are generally larger than the fine pollens of
anemophilous plants. They usually are of more nutritional value to insects, which may use
them for food and inadvertently spread them to other flowers.
