Aziza Cooper sends a photograph of a Pine White caught by a spider, and a free Pine White, from Aylard Farm, September 8.  These were the only butterflies she saw.  Jeremy Tatum writes that he thinks that the spider might be Araneus diadematus, but he is not at all sure.

Kirsten Mills writes:  Jeff Gaskin and I went today, September 8, to McIntyre Reservoir. We saw a Variegated Meadowhawk and a lady. Jeremy Tatum writes:  I had a little difficulty at first in being sure which species of lady it is, but, but after a close look I agree with the unanimous identification by Jeremy Gatten, Gordon Hart and David Harris that it is a somewhat worn West Coast Lady.

Gordon Hart writes:   I attach a photo of a Leaf-cutter Bee, Megachile genus, lifting off from a daisy, at Panama Flats. You can see the large mandibles used to cut circular segments of leaves for its nest. The shutter speed was 1/2500 sec. and still did not stop the wings!

Gordon also shows a photograph of a Bee Fly (Bombyliidae), also from Panama Flats

Jeremy Tatum writes:  Here is a photograph of a moth Xestia xanthographa, which flew into my Saanich apartment today.  This is a European moth, which is fairly common and well-established on Vancouver Island.  Its English name is Square-spot Rustic, although, when talking to myself, I have taken to calling it “X x”.

The Western Tiger Swallowtail caterpillar, shown on September 4, has produced the chrysalis shown below.
