The part of the plant that actually attracts insects is the colorful petals, once they've landed on it, the pollen attached to the stamens makes them stay and gather it. Certain insects can actually sniff out the actual pollen, but its the flower's color that initially draws them in.
The pollen, which is produced by the stamen, or male part of the plant.
The stigma attracts all the insects because when stinking fiys fiy around the plant is because of the pollen!
Nectar
It is not necessary. Some flowers attract insect by their bright color as in case of Petunias.
bright flowers get pollinated because the insect attract them because of the color of the flower

Insect-pollinated flowers usually have sticky pollen to increase the chances of pollen transfer. The stickiness helps the pollen grains adhere to the bodies of insects as they move between flowers, promoting effective pollination. This helps ensure successful reproduction for the plant.
Three flowers that are insect-pollinated are sunflowers, roses, and lilies. These flowers often have colorful petals, strong fragrances, and nectar to attract insects like bees, butterflies, and beetles for pollination.
Different flowers use different methods of attracting pollinators. Some use scent others use colour depending on what type of insect they are trying to attract.
I think you mean which white flowers attract insects in relative darkness. Many night blooming flowers are strongly scented (e.g. cactus blooms) so that they can attract moths at night for pollination
Pollinators are attracted to flowers based on the colors that the pollinators can see. Bees are attracted to blue, purple, and yellow flowers, while butterflies are drawn to red, orange, pink, and purple flowers. This color attraction helps guide the pollinators to the nectar and pollen they seek for food.
