Yes, they do. They are attracted to light so the more ' lighter colored' the flower is, the more tendency that the moth will lend on it.
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
Because they are normally pollinated by moths or bats and have no need to be coloured - they normally have a strong scent to attract pollinators
White flowers smell more strongly than the colored ones so that they can attract the bees for pollination. Since they do not have a color to attract the bees, they naturally smell stronger.
Because, as small inconspicuous white flowers, the only pollinators who can find them are moths, and moths come out at night, when they are more obvious.
As they are pollinated by moths this allows them to be seen.
Pollination of flowers happen through animals and insects.Flowers like jasmine & sepals bloom at night & get pollinated through animals & insects. So,these flowers have special adoptation to attract insects.Have fragrant & white colour are special adoptation.In addition white colour is more visible than other colours in night.Therefore insects attracted to such flowers.
Brightly coloured flowers are normally pollinated by any number of animals and insects. The coloring acts as an attractant to the flower which normally then offers nectar as an additional attractant.Dull coloured flowers (or white ones) are normally attracted to nocturnal animals (bats, mice etc) as well as nocturnal insects such as moths. They also normally have a strong scent as an added attractant.
Tobacco flowers that need moths to pollinate have evolved to have white flowers. Tobacco flowers that need hummingbirds to pollinate have evolved to be deep pink.
The best rule of thumb to use about what moths eat is that they will eat anything that dissolves in water. They will also mostly feed on nectar from flowers.
Because these colours attract insects and the flowers need the insects to pollinate them. Hope this helps!
1. White stands out better in low light conditions making it easier for insects to find. 2. As they bloom at night the plant does not have to waste resources producing coloured pigments (for petals) to attract day insects (such as bees) - most night blooming flowers are pollinated by moths and bats. 3. Night blooming flowers are normally heavily scented - which acts as an attractant for nocturnal insects and mammal's.
