   Libby Avis writes:  Just got back from a great weekend at the Saturna Bioblitz where we ran a moth light on Friday (July 17^th). It was fairly windy and we didn’t get too many moths, but it was made up for by the arrival of this beautiful Lophocampa roseata. We don’t see them very often and this once obligingly hung around and posed.

    Also had a very large, unusual ladybird at the light here in Port Alberni on July 19^th. I had no idea what this was, but it was ID’d on Bug Guide as Myzia subvittata (Subvittate Lady Beetle). Don’t know if you get them in Victoria, but it was the first time I’d seen one.  [Jeremy Tatum responds:  I’ve never seen one in Victoria, but Scott Gilmore found one in Upper Lantzville – see July 12 posting.]

   Scott Gilmore writes:  My son found a nifty fruitfly at a window. I am not entirely sure but I think it is a Rosehip Fly Rhagoletis basiola.  [Jeremy Tatum responds: Well, I’m sure enough of it to label it as such!]

   Julie Michaux writes:  Our 3-year-old grandson picked up this expired specimen from the floor in the garage. We would all like to know its name.  Jeremy Tatum responds: Well! That’s quite a challenge, for it’s well past its Best-Before Date.  It’s obviously a geometrine, but it’s not the usual one, the European Common Emerald.  It is one of our natives.  I cannot be completely sure, but I think it’s most likely  Nemoria glaucomarginaria.

   Aziza Cooper writes: Hello, butterfly watchers,

For the August Butterfly Walk I’d like to suggest that we meet at noon instead of 1pm, and go to Kinsol Trestle, near Shawnigan Lake. It’s the August long weekend, so it will be a good holiday outing and a chance of more variety in butterflies than we are likely to find in Victoria. As always, the walk is dependent on good weather and will be cancelled if the weather is cold or raining.

Jeremy Tatum’s list of butterflies sighted in past years include Hydaspe Fritilliary, Clodius Parnassian, Dun Skipper and Western Tailed Blue. (It could be too late in the year for Western Tailed Blue.)

It’s almost two weeks until August 2nd, the date of the walk. I’m giving the group a bit more time to think about it, since it will be a longer expedition than usual. I’d like to meet at noon instead of 1pm to allow for the driving time which will be about an hour.

Here are the directions:

From Victoria:  From the Trans Canada Highway turn west onto Mill Bay/Shawnigan Lake Road and go all the way into the Village of Shawnigan Lake. Turn right onto Shawnigan Lake Road and follow it until it turns into Renfrew Road. Follow Renfrew road past the end of the Lake to Gleneagles Road and turn right. There is a public parking area about 550 metres down the road on the right hand side. Park here and walk to the Trestle on the Cowichan Valley Trail which is approximately 1.2 km in distance.

Here’s a link to the website:

I’ll send out a reminder notice before the weekend of August 1- 2.

     Aziza Cooper writes:  I went to Moss Rock Park this evening (July 19) and saw 6 butterflies – 4 Painted Ladies, a Red Admiral and a West Coast Lady. The summit is a scramble to get to; quite steep, without a good trail. At Government House, six Western Tiger Swallowtails and one Red Admiral were at the lawn east of the House, and at Mount Tolmie reservoir, another 4 Painted Ladies, a Red Admiral and a West Coast Lady.  Hilltops seem to be the only consistent place to find butterflies around here.  My visit to Goldstream RR tracks was pretty slow, with two Pine Whites, 4 Lorquin’s Admirals, and 10 skippers, mostly Woodland.

   In case any viewers have not yet visited Mount Washington to see the wonderful butterflies there, here is today’s contribution from Mike Yip:  A leisurely trip to Mt. Washington on Friday (July 17) yielded 15 species. First stop was at the start of the Mt. Washington road where we encountered 4 Common Woodnymph and several Woodland Skippers. Before we got to the first ski hill we had added Grey Hairstreak, Lorquin’s Admiral,  Cabbage White, Mariposa Copper, Hydaspe Fritillary, Anna’s Blue, Silvery Blue, Painted Lady, Clodius Parnassian. At the first ski hill we added Purplish Copper and Common Branded Skipper. We only spent 20 minutes at the peak but added Great Arctic and Anise Swallowtail. In all we found 3 Painted Ladies –  all new generation in mint condition. The Great Arctics were all fairly well worn and in poor condition. Silvery Blues were also near the end of their days.

   Annie Pang sends three recent photographs of the Large Yellow Underwing moth – a European invader.  Her pictures give examples of the fairly large variability of the species, but the dark double dot near the apex of the forewing is diagnostic.

   Jeremy Tatum visited Mount Tolmie at 7:00 pm on July 18 and found, in addition to Painted Ladies and Red Admirals, a West Coast Lady – scarcely recognizable as such, but still flying strongly and indulging in frantic chases with other butterflies.

  Aziza Cooper writes:  This evening, July 18, I went to two hilltops in Fairfield and Oak Bay and found butterflies at both of them. At Gonzales Hill off Fairfield Road at about 7:30pm, two Painted Ladies were interacting at the lawn next to the parking lot. At Anderson Hill about 8:00 pm, one Red Admiral and one Painted Lady were at the top of the hill next to the chain-link fence on the eastern boundary.

With Mt Douglas, Mt Tolmie and Government House, this makes five hilltopping locations in Victoria. Other summits would be worth checking, for instance, Moss Rock Park, Highrock Park in Esquimalt, Mill Hill, Knockan Hill and Christmas Hill. If anyone is hiking in late afternoon or evening, please check Observatory Hill, Jocelyn Hill and Mount Work.

Any other rocky summits would also be worth checking. Probably there are hilltopping butterflies at Goldstream Heights, Spectacle Lake and other locations further out.
