Where do woolly aphid colonies characteristically cluster on affected host plants?

Answer

Near feeding sites such as young twigs, branches, or sometimes on roots.

Woolly aphids generally do not exist solitarily; they express their characteristic physical presence through aggregation. These pests tend to form dense clusters where they can efficiently feed. The common locations for these feeding sites include areas with readily accessible phloem, such as young twigs, branches, or stems. Depending on the specific species of woolly aphid, aggregations may also be found on the roots of the host plant. The formation of these dense clusters is what generates the prominent, visible white mass associated with an infestation.
