   Jochen Möhr sends a photograph of a European Winter Moth from Metchosin.   Now we need someone to go out to the Goldstream Park Nature House and photograph a native Bruce’s Winter Moth for us!

   Libby sent several photographs (two below) of Winter Moths from Port Alberni.  We think they are all O. brumata.

   Libby writes from Port Alberni that she had two Mythimna unipuncta a couple of nights ago, and a Dargida procincta last week.


   Jeremy Tatum writes:  Here is a rather typical European Winter Moth Operophtera brumata from my Saanich apartment this morning, and, below it, another one, much more strongly marked, from UVic.

    Jeremy Tatum writes:  In the November 3 posting, I said I’d look up the date of the last 2017 butterfly.  It was a Cabbage White on 2017 November 1.  Thus Kirsten’s November 2 sighting of a Cabbage White this year beats last year’s by one day!   

  We may have seen the last butterfly of the year, but there are still a few invertebrates around, so Invert Alert will remain open, though doubtless at a reduced rate of activity, so please continue to send your observations or photographs in.

   Jochen Möhr sends photographs of two moths from Metchosin.  One is Drepanulatrix sp. – I think D. monicaria.  The other is Epirrita autumnalis.

   Kirsten Mills writes that she saw a Cabbage White yesterday, November 2,  at Eddy’s Storage on Stelly’s Cross Road.   This is surely going to be a good candidate for last butterfly of the year!  I’ll have to look it up when I get a moment, but I believe that November 2 last year was also the date of the last butterfly – a Cabbage White.   I’ll post a confirmation when I have had a chance to search last year’s records.   Jeremy Tatum
