insect pollinated flowers are brightly coloured and sweet scented so that the plant can attract the insect towards itself.
Because the pollen could stick on the insect to polinate.
Insect pollinated. Wind pollinated stigmas are generally feathery.

The pollen grain is usually sticky and bright in color. These are the features that make the pollen grains suited for being brushed off by an insect.
The stigma of a flower is sticky in order to aid in the reproduction of the flower. The stickiness allows pollen to adhere to the stigma, a sexual organ. This sticky stigma also prevents unwanted organisms and insects from penetrating the plant.
There are two types of pollination, cross pollination and self pollination. self pollination occur when male part (androecium) of the flower of one plant pollinated on the female part (gynoecium) of the same individual. usually plant with self pollination will have characteristics like: 1. the anther and the stigma are matured at the same time - meaning the stigma are ready to receive the pollen grains at the same time as the anther mature to release it pollen grains. 2. the pollen grains and the stigma are compatible. (means stigma can accept the pollen grains-there is no rejection of pollen grains)
Insect pollinated is attractive and colourful, the former isn't Besides petal color the insect pollinated flowers also have insect attracting smell where as in wind pollinated flowers the petals are neither attractive nor scented.
The pollen grains of wind pollinated plants are generally smooth and light. These are not sticky to avoid clump-sing. These are produced in large numbers to ensure landing some pollen on the feathery or netted stigmas.
Insect pollinated. Wind pollinated stigmas are generally feathery.

Wind pollinated flowers have sticky stigma
Sticky stigma is generally present in wind pollinated flowers.

plants with sticky stamen, flowers have nectories

Bright-colored, nectar-containing, nice-scented petals with firm, sticky pollen-producing anthers and firm, sticky-coated stigma inside the blooms are what tell -- just by looking -- that a flower is insect-pollinated. The structural looks back up the function-serving purposes of attracting insects (bees, butterflies) to fulfill feeding requirements through nectaring in order to have pollen moved between male and female parts for reproduction.
The pollen grain is usually sticky and bright in color. These are the features that make the pollen grains suited for being brushed off by an insect.
Its the wind that carries the pollens. The flowers swells sticky substance that catches the pollen grains
