Rosemary Jorna photographed this dragonfly at Sooke Potholes on September 12.\u00a0 Dr Rob Cannings writes to Rosemary:<\/p>\n

The Variable Darner<\/strong> 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 \u2013 thus the name \u201cinterrupta<\/em>\u201d) to very thin lines, mainly in the BC \u00a0Interior 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.<\/em> palmata<\/em> and A. umbrosa<\/em>. The black line on the face (as distinct from some species such as A. canadensis<\/em>, which has a pale brown line) is also a useful field mark.<\/p>\n

So what you have is a female Variable Darner\u00a0 Aeshna interrupta<\/em> . It\u2019s the yellow form \u2013 they also come in a less common blue form, coloured more like the males.<\/p>\n

Jeff Gaskin writes:\u00a0 Here is a list of dragonflies I saw today, September 13, at Swan Lake:<\/p>\n

2 Blue Dashers,\u00a0 4 Blue-eyed Darners<\/strong>, and 1 Paddle-tailed Darner<\/strong>.<\/p>\n

I only saw the odd Cabbage White<\/strong> at Swan Lake today, nothing else.<\/p>\n
