Insect pollination is necessary for most flowering plants. In fact, flowering plants and insects are tied together on many other levels including food and shelter. In some examples insects and flowering plants have appeared to evolve together eg. Figs and figwasps (family Agaonidae).
The large Australian family, Myrtaceae, which includes the genera Eucalyptus, Angophora, Leptospermum (tea-trees) and Syncarpia (turpentine), are largely pollinated by insects, although fruit bats and birds are also involved. As a result of the predominance of insect pollinators the flowers tend to be small but rich in nectar and pollen. The large - flowered Proteaceae (Banksias and Grevilleas) attract and depend on birds as their chief pollinators.
Many people tend to think of honeybees as the main visitors to flowers but other insects that are highly involved are beetles, ants and flies. The following photographs illustrate the kinds of insects that are important in this process.
