Recently larvae of cherry ermine moth, Yponomeuta
padella, were found defoliating a Prunus tree in a landscape
in Olympia, Washington. That is a new host record for this moth in North
America. It has been trapped in low numbers in 1995 in Centralia and found
causing minor damage on another host, hawthorn in the Bellingham area.
