Woolly vine scale (cottony vine scale), Pulvinaria vitis, on a stem of Ribes speciosum. The picture shows two adult female scale insects (lower brown, upper with white covering). The white covering is the ovisac, made from wax secreted by the female, and into which she lays her eggs. P. vitis is a sap-feeding bug named after the grape vine (Vitis vinifera), but can be found on a variety of other plants, including apricots, peaches, and members of the Ribes genus, such as blackcurrants, redcurrants and gooseberries. R. speciosum is an ornamental currant native to California, grown in gardens for its display of scarlet fuchsia-like flowers in vitis is of little economic importance, although heavy infestations in orchards may amount to a nuisance, as wasps and other insects are attracted to the honeydew secreted by the scale.
