Definition
A woolly adelgid is a type of aphid-like insect that produces a white, waxy or "woolly" coating on the branches and needles of its host tree. This coating is a protective covering for the insects. 🌲 They feed on the sap of conifers, especially fir and hemlock trees. Infestations can cause significant damage, including stunted growth and eventual tree death. The white, cotton-like appearance is a key indicator of their presence. It's like the tree is wearing a tiny, fuzzy sweater, but it's actually being attacked.
