Solution

Insect visit flowers to get nectar. Nectar is contained in a special gland called nectary and sometimes in a special structure called spur. The attraction of flower in plants is not to diverge the insect from damaging other part, but to bring about pollination (i.e. transfer of pollen to the stigma). The pollen grains in insect pollinated flowers are either sticky or provided with spinous outgrowths. The stigma is also sticky. Insect often visiting these flower for nectar and bring about pollination inevidently.
