   Here is a photograph of a slug taken by Ian Cooper at Colquitz River Park.  We are grateful to Robert Forsyth for confirming that it is almost certainly Ambigolimax valentianus.  “Almost certainly” , because “there is always the chance that it is another Ambigolimax, such as A. parvipenis, which is in California”, but which cannot easily be distinguished externally.  “It is not yet known from BC, but it is widespread in California.”

Ian also photographed this noctuid caterpillar, whose identity we have not yet determined.
