Pollinator Pollinator A pollinator is an animal that moves pollen from the male anther of a flower to the female stigma of a flower. This helps to bring about fertilization of the ovules in the flower by the male gametes from the pollen grains. Insect pollinators include bees, (honey bees, solitary species, bumblebees); pollen wasps (Masarinae); ants; flies including bee flies, hoverflies and mosquitoes; lepidopterans, both butterflies and moths; and flower beetles. Vertebrates, mainly bats and birds, but also some non-bat mammals (monkeys, lemurs, possums, rodents) and some lizards pollinate certain plants. Among the pollinating birds are hummingbirds, honeyeaters and sunbirds
Heliconius charithonia and show superior mimetic diversity to those that do not. Adult butterflies choose their home ranges based on collections of pollen plants. An adult collects pollen by inserting its proboscis into the flower while making particular movements to secure adhesion to the pollen grains. Digestion occurs immediately after ingestion when the pollen makes contact with saliva, and amino acids are dissolved. Optimal amino acid intake occurs through abundant saliva production and gentle and slow mastication. During the night, the butterflies digest pollen since optimal nutritional resources are obtained while resting or sleeping. Pollen feeding is correlated with higher overall fitness.
