Val George writes: This Vancouver Looper, Erannis vancouverensis, was on the wall of my Oak Bay house this morning, November 18.
Jeremy Tatum writes: This species needs some careful work by professional taxonomists. It is a very abundant moth here, and is indeed usually called Erannis vancouverensis. Followers of this site may have noticed that I have often written that I believe it is actually the European species E. defoliaria. I have been assured many a time that defoliaria and vancouverensis are different species. Perhaps so, but this does not answer the question as to which of the species occurs here in the Victoria area of Vancouver Island. I see no obvious difference between Val’s moth and defoliaria. More work is needed.
