    Jochen Moehr sends photographs of Winter and Autumnal Moths from Metchosin.  We are also looking out for the native Bruce’s and Danby’s Winter Moths, as well as Erannis vancouverensis. There were very much fewer caterpillars of vancouverensis this spring compared with most years, so there may not be many adults around now.  Try Goldstream Park for bruceata and danbyi.

   Jochen Moehr sends pictures of two White-speck Moths from Metchosin yesterday.  This is the adult of the caterpillar known to agriculture as the Armyworm (see September 12).

Jochen also sends pictures of three geometrid moths.  Now, are these the European Winter Moth?  They look slightly different, so maybe they are Bruce’s?  Isn’t it hard!  Actually, although some Winter Moths are already around, it’s not quite winter yet – it is still autumn, and I believe all three of these are in fact Autumnal Moths.  See the row of double dots along the outer margin (termen) of both the fore- and the hindwings.  Also, Jochen’s moth of November 8 –  I had labelled it as a Winter Moth, but it is a very worn specimen, and if you look along the outer margin carefully, you can just make out the double spots – or at least where they were.  I have relabelled the November 8 moth an Autumnal Moth

 

Will someone go to Goldstream Park Nature House and try and get a photo of Bruce’s Winter Moth for us?
