Just found this on www...
"Pulvinaria regalis was first recorded in Britain in about 1964 in Kew, London and has since become widespread throughout Britain. It is the most abundant soft scale insect in urban areas and is also common in many rural areas in Britain. It has also spread throughout north-west Europe."

"The adult scale insect resembles a limpet and remains stationary on the bark of its host tree where it feeds on sap. Although males can occur, the insects are normally all female, and reproduce by parthenogenesis.[4] In early summer, the mature female lays white, circular egg masses which become visible as they protrude slightly from under her brown scale. The eggs hatch into nymphs which crawl away from the mother along the branches to find foliage, where they start to suck sap. In the autumn, they return to the trunk and larger branches where they spend the winter as flat scales about 1 mm (0.04 in) long. They resume feeding in spring and are fully grown by early summer. There is a single generation each year and the adults die after reproducing.[2] This insect has glands that produce several forms of wax; some glands produce water-repellent wax that keeps the air passages leading to the spiracles open. Other glands produce long white filaments of wax that serve a function in the construction of the sac that surrounds the eggs. To avoid getting contaminated by its own honeydew, the scale insect has a six-bristled mechanism close to the anus, with which it can flick away its excrement.[5]"
