This morning someone asked a pest ID question. There are accurate answers in the comments sections, but posters were reluctant to write in the Answers section as other questions had been answered about the same pest.
The examples given were, indeed, about the same pest, but they were quite different - different host and different pest manifestation.
I feel like the second question provides a valuable different perspective on this pest (wooly aphid), so I wonder how best to make sure that it is found by people searching for white fluffy pest.
