there are flowers that are self pollinating
It depends on what color. Honey Bees are typically attracted to "warm" colors (red orange yellow etc.), whereas butterflys like "cool" colors (blue purple cyan etc.)
Hibiscus is actually pollinated by hummingbirds! Red flowers always most likely are because birds can see red better than insects (they're better at the blue and purple part of the spectrum). Also, the pollen is far away from the nectar. If a hummingbird puts its tongue into the flower, the pollen will be deposited on its back. An insect would never touch the pollen when crawling into the flower to the nectar. ^^
The pride o barbados is insect pollinated because it produces sweet nectar and is brightly coloured which attracts insects.
It's bright and showy, and even has little nectar ducts under its petals, so insect-pollinated. Wind-pollinated plants generally don't have flowers, or the flowers are very small and inconspicuous, like those of grass. Wind-pollinated plants also make far more pollen (try tapping a pine tree or reed in spring) because the wind does not take it directly to its destination, much of it will be lost. With insects there's a fair chance the little there is will reach another flower of the same species.
nectar and pollen
Well, butterflies normally eat nectar from flowers, so we can assume that they drink the nectar from flowers.
The nectar has a pollinated job for it.
Nectar is produced by flowers to attract insects, bats or birds that will help to carry its pollen to other plants (and bring fresh pollen to it). If a plant is pollinated in the wind, then it doesn't need to spend the energy to make nectar.

Nectar
Flowers are pollinated (fertilized) by insects unwittingly transferring pollen from one flower to another as they move from flower to flower drinking or collecting nectar.
Honeysuckles, hence their name, are bountiful with nectar. Bees live on nectar and pollen and are attracted to the honeysuckle's flowers.
Animals looking for nectar spread pollen
By the color. They are attracted to bright colors like red and pink. They have very keen eyesight and can spot "red" from a great distance.
Wind-pollinated plants do not need colorful flowers as they are not pollinated by animals, insects or birds. Since wind-pollinated plants do not need colorful flowers, they might as well put their energy into making their pollen lighter, or more of it.
