We start today with photographs (by Ian Cooper, along the  E&N & Galloping Goose Trails last night) of a magnificent insect.  Hard to believe, until you look at it carefully and critically, that this is a moth. And no, it doesn’t sting.  It belongs to the Family Sesiidae (clearwing moths).  Most of them are excellent at mimicking other insects; many of them, in particular, look very convincingly like Hymenoptera.  The caterpillar of this one is hard to find (unless you are a raspberry farmer) and it is known as the Raspberry Crown Borer.  The caterpillar lives inside the stalks and buds and even the roots of raspberries and blackberries.

Jeff Gaskin writes:  Today, September 5, in Esquimalt Gorge Park I saw a Black Saddlebags and at least two Paddle-tailed Darners.  The only butterflies I saw were Cabbage Whites.   (Jeremy Tatum writes:  There were still several Cabbage Whites today at Mount View Park, off Carey Road.)  Jeff and Kirsten Mills saw an Autumn Meadowhawk at Cowichan Station yesterday.

The moth below appeared at Jeremy Tatum’s apartment in Saanich this morning, September 5:

Aziza Cooper photographed the fly below on Mount Douglas in mid-August.  We are grateful to Dr Jeff Skevington, who has identified it as a species of bee fly (Bombyliidae) in the genus Villa.

Aziza visited Island View Beach today, Septmber 4.  She writes that there were three Purplish Coppers, one California Ringlet, five Woodland Skippers and nine Cabbage Whites. An aeshnid dragonfly was perching vertically.  Dr Rob Cannings kindly identified the aeshnid as a male Shadow Darner.  Aziza sends the following photographs.

Marie O’Shaughnessy photographed this exuvia at Esquimalt Lagoon, September 2.  Amazingly, Dr Rob Cannings managed to identify it.  He writes: This is Rhionaeschna multicolor. The width and length of its labium are measurable, so there is no doubt.

   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.
