    Perianth
    Bright colors - may be specific for the type of insect. Large, conspicuous petals and/or sepals The flowers produce scent to attract the insects. Nectar may be produced as a food reward. Nectar is high in sugars and is produced at the base of the flower to increase the chances of the insect moving against the anthers and stigma. Some insects, such as beetles, feed on the petals.
    Flower
    Many are bisexual flowers - each visit by the insect is more efficient because the insect can both pick up and deliver pollen. Varieties of floral shape and size. Some orchids have elaborate shapes that mimic female insects.
    Stamens
    Pollen grains may be packed with starch or oils and thus are an important source of food. Less pollen is produced. The exine of the pollen is contoured and shaped to help it cling to the insect. The structure of the exine is specific for the various plant groups and is used as a diagnostic feature.
    Pistil
    The stigma is within the perianth - the insect is forced to move against stigma when moving inside the perianth. Simple or compound carpels are present.
