Notes: Parthenolecanium fletcheri (Cockerell), a North American pest of cypress (Thuja) and yew (Taxus), was first recorded in Europe in the 1930s and has since spread widely in continental Europe. In June 2011 a mature western red cedar (Thuja plicata) tree in Pimlico, London, was found to be infested with P. fletcheri. This is the first time that this scale insect has been found breeding in Britain. The host range, biology, geographical distribution and economic importance of P. fletcheri are reviewed.
