Mature scale attach themselves to the vine and excrete honeydew that may lead to sooty mould. Vine scales produce a number of eggs over several days. The eggs are laid under the cover of the adult "scales" which offer protection.

In this case shown vine scale are aggressively sucking sap from this Cabernet Sauvignon vineyard. If left without treatment vine scale will likely kill this grapevine.
