day as I was cutting back the heavenly blue
morning glories in my yard, I noticed large numbers of the barnacle
scale insects on the vine.
adult barnacle scale is shown in the center, with nymphs off to the
right. Also near the adult is an argentine
ant. Ants tend barnacle scale the way they do other
honeydew producing insects.
honeydew from the barnacle scale insects drips on leaves, or anything
else below, providing nutrition for a sooty mildew fungus.
Resulting in a sticky black mess.
first time I encountered the barnacle was not in my yard, but in street
trees not far from home. Here it is seen in a jacaranda tree.
