How to recognize cottony camellia scale 

Young stages of the cottony camellia scale are light brown and flat. Adult stages are elongated and somewhat convex shaped. From June and July the scales produce long, straight and white egg sacs on the leaves. These egg masses are usually smaller compared to egg masses from other scale species. During summer, the eggs will develop into crawlers. This first stage is very mobile and spreads throughout the plant. Overwintering occurs on the leaves. 

Cottony camellia scale damage 

Damage by the cottony camellia scale is mainly cosmetic. During heavy infestations, large amounts of honeydew are produced. The honeydew acts as a growth medium for black sooty mold fungus which will turn the leaves black. This can hamper photosynthesis.
