   Marie O’Shaughnessy writes:  I visited several places on September 1 and 2 looking for birds, dragonflies and butterflies. All I saw were Cabbage Whites one at each of these places:
Cattle Point, Bowker Avenue, Outerbridge Park, McIntyre Reservoir, Esquimalt Lagoon, plus three more Cabbage Whites while I was driving along Blenkinsop Road. Dragonfly numbers are way down.

Outerbridge Park had 2 Paddletail Darners and 1 Cardinal Meadowhawk.

Kirsten Mills writes on September 2:     Jeff Gaskin and I were at the ponds on Green Park Drive and saw a Cardinal Meadowhawk.  Photos were taken and also there were three Paddle-tailed Darners.  Green Park Drive is near Swartz Bay in North Saanich.

Gordon Hart writes:  Here is a summary of yesterday’s Butterfly Walk There were no butterflies at Mount Tolmie at 1 p.m. but we decided that Island View Beach might be a good place to look. Six people made their way there, and decided to take the beach path as we thought it might be a bit cooler closer to the water. It was still very warm, but we did see at least 23 butterflies of three species, plus a mystery moth in flight, and several bee and wasp species. Butterflies seen were: Cabbage Whites, 7+; Purplish Coppers, 3 males, 3 females; and Woodland Skippers, at least 7.
The moth was possibly a Vapourer Moth, or Rusty Tussock Moth, inferred from its manner of flight.

Jeremy Tatum adds: The Purplish Coppers were the first reported this year.  I was afraid that we might go through the whole year without any being reported.  The first two seen on yesterday’s walk were a male and a female (they are quite distinctive), being very cooperative as they nectared on the flowers of a nearby Gumweed.  They caused great excitement among the participants, several of whom were armed with big cameras, which were fairly clicking for several minutes.

Here are some photographs taken during the walk.  Note the copper’s scientific genus name change from previous years.

Ian Cooper has been away in Ontario for a while visiting relatives.  He is now back and has wasted no time in getting his camera clicking here again on the Galloping Goose trail near Talcott Road in View Royal, August 31.

Gordon Hart writes: At Whiffin Spit today, Anne-Marie and I finally spotted something other than a Cabbage White. It was “only” a Painted Lady, not the American Lady, but still nice to see. It was nectaring on Sea Rocket. Interesting that the Cabbage Whites seemed to prefer the yellow Gumweed flowers, but the Painted Lady went from plant to plant of the Sea Rocket.

No Invertebrate Alert was issued on August 30.

The Monthly Butterfly Walk will take place tomorrow, starting at 1:00 pm on top of Mount Tolmie. For the formal announcement and other details, see the Invert Alert posting for August 29 evening.  All welcome.

Richard Rycraft writes: I saw a couple of Woodland Skippers yesterday afternoon feeding on the Lavender in my Oak Bay garden..  I used to see many, but local development has reduced the wild grass areas that used to be nearby.  Plus the usual Cabbage Whites.

Many viewers, I suspect, writes Jeremy Tatum, will have observed that Lavender seems to have a special nectaring attraction for Woodland Skippers.  The caterpillar feeds on grasses – hence Richard’s reference to the lost grass areas.

Jeremy Tatum sends a photograph of a moth from his Saanich apartment this morning.  This one, the Square-spot Rustic, like the Large and Lesser Yellow Underwings¸ is a European moth that has somehow established itself here.
