Sucking and piercing members of the insect super family Coccoidea are the mealybugs and they are known to commonly attack houseplants. They are also capable of affecting the growth of plants in your garden and they also have a varying range in size which is dependent on species and maturity level.
When they attack an outdoor plant, these bugs tend to live in colonies and when laying eggs, the female mealybugs always have this cotton patches appearance. The adult mealybugs are not seen always and they also have two wings.
The mealybugs that are just hatched are pinkish or yellowish in color and they are more mobile than the adult mealybugs and also the nymph stages. The effect of mealybugs in your garden is that they limit the vigor of your plants and this is a bigger problem when they suck sap from stems and leaves in large populations.
Mealybugs also tend to secrete sugary excrement known as honeydew when they feed on a plant and it results in a sooty mold fungus developing on the honeydew.
The effect of all these on plants as well is that it cuts down the ability of these plants to carry out photosynthesis and this in turn causes these leaves to fall off and die.
