introduced or spread?
John, do you happen to know whether this moth was introduced locally to control St. Johnswort? It was introduced to BC in the 80s for that reason, and I think stock may be available for release elsewhere.
Or... if the species has spread to the southern border of Washington from BC, perhaps it's now in Oregon too (?) [the first US record was 3 years ago near Plattsburgh, New York, having spread from an introduction in eastern Ontario]

 
Aplocera
I'm not sure if it was introduced in our immediate area, but it seems fairly common. We have St. Johnswort in our area, but it's not real dense. I'll try and find out about the introduction.
