Symbiosis is a relationship between organisms in which both organisms benefit. One example is the relationship between flowers and butterflies. The flower depends on butterflies and other insects for pollination and the butterfly depends on the flower for food.
Does a butterfly feed on any kind of flower?
No. In fact, different butterflies are attracted to different flowers depending on the flowers physical characteristics.
Some flowers have marking that the human eye cannot see, but is visible to some insects, including butterflies. For more information about invisible flower markings, see HONEY GUIDES.
