   Technical note: Contributors may have noticed that for a long time their photographs were being reproduced on Invert Alert at rather a small size.  In most cases this was a result of a computer problem that I could not overcome.  I seem to have partially solved the problem now, and most photographs will be shown at a decent size. The only problem now is that I cannot see the posting on my computer before I press the Send button, and I have to hope for the best.

  Today: More middle-of-the-night denizens of the Galloping Goose trail in View Royal, photographed by Ian Cooper in the early morning hours of November 25.

    Ian Cooper writes:  I went on a very productive, multi-hour photoshoot overnight (November 25 morning) at Colquitz River Park in Saanich and the Galloping Goose Trail in View Royal. Recent precipitation and mild weather seem to have brought many critters out of the woodwork and leaf litter, some of which I’d not seen in many months. The photo-shoot ended only because it started to rain around 6:00 a.m. in View Royal. Luckily, I had rain gear on, as it rained continuously on the 40-minute ride back to James Bay.

The identifications below are the best that Ian and Jeremy Tatum can come up with.  We make no claim to be experts, but we have given them all some thought and we believe they are all “probably or better” correct.   If anyone disagrees, or can go further, do please let us know.

Jochen Möhr writes from Metchosin: After a long hiatus, an Erannis vancouverensis was on our wall yesterday morning.

Erannis vancouverensis/defoliaria (Lep.: Geometridae) Jochen Möhr


Jeremy Tatum writes:  I retain my long-held suspicions that this may actually be the European E.defoliaria.    Also, in Saanich, I have had the same experience as Jochen, with a long hiatus.  Until yesterday, November 23, I had seen only two Winter Moths this November – on November 11 and 15.  Then suddenly, yesterday, four turned up at the back door of my apartment building.


Yesterday, November 23, Jochen also photographed the beautiful moth below,which we have not yet identified.

Awaiting identification
