    Jeff Gaskin writes: Today, September 14, I found three  Woodland Skippers in the community garden at Gorge Park.  I heard from Geoffrey Newell today about some nice butterflies he found on September 9.  First of all he saw a Mourning Cloak at Esquimalt Lagoon and then he saw three Pine Whites at Witty’s Lagoon.

 

  Here is a harvestman, photographed by Ian Cooper and kindly identified for us by Dr Philip Bragg:

   Ian Cooper photographed a Drone Fly Eristalis tenax at Colquitz River Park, September  8.  Viewers might like to compare it with the somewhat similar E. arbustorum, shown on August 24 evening.

   Ian photographed a male and a female Common (European) Earwig.  Note the shape of the pincers.

Rosemary Jorna photographed this dragonfly at Sooke Potholes on September 12.  Dr Rob Cannings writes to Rosemary:

The Variable Darner lives up to its name and the lateral thoracic stripes vary from being divided into spots (in BC mainly west of the Coast Mountains and in eastern North America – thus the name “interrupta”) to very thin lines, mainly in the BC  Interior and on the Great Plains. In females especially, even on the Coast, the stripes can be undivided and rather broad, as in your specimen, but are almost always not parallel-sided as they are in A. palmata and A. umbrosa. The black line on the face (as distinct from some species such as A. canadensis, which has a pale brown line) is also a useful field mark.

So what you have is a female Variable Darner  Aeshna interrupta . It’s the yellow form – they also come in a less common blue form, coloured more like the males.

Jeff Gaskin writes:  Here is a list of dragonflies I saw today, September 13, at Swan Lake:

2 Blue Dashers,  4 Blue-eyed Darners, and 1 Paddle-tailed Darner.

I only saw the odd Cabbage White at Swan Lake today, nothing else.

Val George writes: This deceased Large Yellow Underwing  Noctua pronuba was on the ground by my front door this morning, September 13. It afforded me the opportunity to show its yellow hindwings, which are rarely apparent in photos of live specimens.
