I see these often in Colquitz River Park. They look like miniature houseflies,
but with proportionally larger iridescent wings.

   Jeremy Tatum writes:  Owing to some procedural error in my posting of yesterday’s photographs, some of the photographs did not appear as sharp as they should have done.  I have removed them from yesterday’s posting, and I’ll make another attempt here.  ‘Pologies to all.

Aziza Cooper wrote: At the field north of Stelly’s Cross Road and West Saanich Rd. there were 17+ Essex Skippers. Further north near the cemetery along W. Saanich Rd. there were two Field Crescents.

Ian Cooper photographed the fly shown below.  We have not been able to identify it with certainty. Jeremy Tatum suggested Psilidae, but we cannot find a good fit.  If any viewer can help with this identification, please do let us know.

Sympetrum  sp. (Odo.: Libellulidae)   Marie O’Shaugnessy


Marie also photographed this exuvia.  Dr Rob Cannings rises to the challenge and writes:
The exuvia is definitely an aeshnid by its form. The view doesn’t show the characteristics required for a foolproof identification, but it has the short labium of a Rhionaeschna (and it just looks like one to me – hard to describe why). Because we are at the height of the appearance of R. multicolor and R. californica, emergence is probably mostly over, my guess is that this is a Blue-eyed Darner exuvia. The fact that this species is the most common darner around here in the summer just adds to the high probability. And the local Aeshna species have hardly begun emergence yet.

Jeremy Tatum shows a small moth reared on blackberry from a caterpillar found at Swan Lake.  Thanks to Dr Jason Dombrowskie, who writes:  I’m 95% sure that is a female Archips rosana.
