Jeremy Tatum writes:  Here is an objet trouvé from Swan Lake.  It is the empty skin of a chrysalis of a Lorquin’s Admiral hanging from an apple tree.  The butterfly probably emerged from the chrysalis several months ago.

   The Cabbage White chrysalis below, however, is occupied!   The butterfly might emerge later this year, but more likely next spring.

Jochen Moehr sends some moth photographs from his home in Metchosin.  We are very grateful to Libby Avis for identifying them for us.

The next one is a pug, and they are always difficult.  Libby expresses some caution for her identification as probably E. graefii, though I think she has it just right.  Looks like a very good fit to me (Jeremy Tatum)

Libby writes that she has been seeing more than usual Nepytia phantasmaria in Port Alberni. She writes:  Over a two week period at the beginning of September we were getting 10 or 12 a night – actually counted 28 on Septeber 6!  I have attached a photo of three of them from September 4.

Mike McGrenere writes:     I had an Orange Sulphur last Sunday (September 10) at McIntyre reservoir along with an American Lady. There were about 40 Cabbage Whites as well. Yesterday (September 15) at the reservoir, there were only about 5 Cabbage Whites. I have attached photos of the butterflies.

   Jeremy Tatum reports a Red Admiral perched on the Mahonia just outside the entrance to the Mount Tolmie reservoir, 5:45 pm today.

Annie Pang is bravely taking on the task of rearing a caterpillar of a Spotted Tiger Moth – feeding, unusually, on birch.

   Jeremy Tatum had two moths outside his Saanich apartment this morning:

The photographs are deceiving – pronuba is about twice the size of xanthographa!

With our last 2017 butterfly count starting this weekend, I thought I would send a summary of the August count. In 2016 a dry summer resulted in very few butterflies flying for our count: 9 species and 709 individuals. In August 2017, we had much higher numbers: 14 species and 1328 individuals counted. Both Cabbage Whites and Woodland Skippers had hundreds more counted, with every species having more than 2016.

Hello Butterfly Counters!

The last butterfly count period for 2017 will begin Saturday, September 16 running until Sunday September 24. Please use the submission form on the VNHS website: www.vicnhs.bc.ca/?p=33. 

You can submit a count anytime over this period, and you can do more than one count, just use a separate form for each count. In the case of repeat counts, or more than one person counting an area, I will take the highest count for each species. The count area is the same as the Victoria Christmas Bird Count circle. For butterfly identification there are numerous internet sites, but most or all Victoria species are listed on E-Fauna. If you select by photographer, all the photos under James Miskelly’s name are of Victoria species. Here is the link: http://linnet.geog.ubc.ca/efauna/photoGallery/Gallery.aspx?gr=showall&pid=175&photographer=miskelly,%20james&specrep=0

If you need suggestions for a place to count, please email me.  If you want to be removed from this list, please let me know. If you know someone who wants to be on the list, please ask them to email me.

Last year was very dry, with few butterflies – all Cabbage Whites and Woodland Skippers. I think this year we should have a bit more variety!

Thanks for participating in the count!

   Barbara McGrenere reports finding a caterpillar (shown below) of a Rough Prominent moth at McMinn Park (Cordova Bay) and seeing a Painted Lady butterfly at Outerbridge Park (Royal Oak Drive) this morning.

   Jeremy Tatum writes:  Lots of Neoalcis californiaria keep coming to my back door in Saanich.

      He also reports a Red Admiral just outside the entrance to the Mount Tolmie reservoir at 4:00 p m.

In yesterday’s (September 12) posting I recounted how I had seen a huge Catocala  very close by in flight.  It turns out that on the very same day Gordon Hart had exactly the same experience in his Highlands yard.  As with me, shortly after flying around, the moth settled in full view, the one difference being that Gordon had his camera with him!  These “cats” are difficult to distinguish, even if they show their colourful hindwings, and I think we’ll have to leave this as Catocala sp.

   Also seen by Gordon was a Painted Lady, which, very appropriately, settled on a butterfly-shaped sundial for its photo opportunity.

   Jeremy Tatum writes:  My pessimism expressed in the September 11 posting about being able to get an identification of the moth photographed by Ron Flower at McIntyre reservoir yesterday was ill-founded.  Libby Avis had no difficulty in identifying it as Loxostege cereralis – named for Ceres, goddess of agriculture.  Here is Ron’s photograph:

   The September 10 posting had a report of masses of caterpillars of the White-speck Moth (Armyworm) invading a school in Courtenay.  Now today’s (September 12) Times-Colonist has an article (page B1) headed “Armyworm infestation decimates BC crops”, including such phrases as “seething mass” and “army of voracious worms”, “a larvae” and so on.  I haven’t seen any here in Victoria recently.  Perhaps viewers would keep a lookout for them.  I see many buildings were also decimated by Hurricane Irma.  I always thought that “to decimate” meant “to reduce by ten percent” – but I suppose our language evolves and becomes less comprehensible as it does so.

   Jeremy Tatum writes:  I visited McIntyre reservoir again today.   I saw a Painted Lady, a Purplish Copper, and lots of Cabbage Whites – but no sulphurs.  That does not mean that they have all necessarily gone, and it would still be worth a few visits there.  I had some excitement at the Lochside trail pig farm.  A huge Catocala moth flew right by my head, flashing brilliant red hindwings.  You usually find these moths settled on a wall with their hindwings hidden.  To see the moth in flight was quite exciting.  Later it settled on a branch.  I couldn’t be sure of the species, but, although there were no nearby oaks, I believe it was most likely C. aholibah.  Then, a little bit further south on Lochside, I found several nests of the Fall Webworm, and I found an isolated caterpillar that had left its nest.  It can be surprising to discover that the Fall Webworm is actually a woolly bear, every bit as woolly, soft, long-haired and cuddly as the other woolly nears in our area.
