Please send your sightings by email to Jeremy Tatum (tatumjb352@gmail.com). Be sure to include your name, phone number, the species name (common or scientific) of the invertebrate you saw, location, date, and number of individuals. If you have a photograph you are willing to share, please send it along. Click on the title above for an index of past sightings.The index is updated most days.

   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.

Marie saw these between 4 and 5 pm at Government House on June 24:

4 Western Tiger Swallowtails
2 Cabbage Whites
6 Essex Skippers
1 Lorquin’s Admiral
1 Blue-eyed Darner.

 She photographed one of the Western Tiger Swallowtails:

Mosquito  (Dip.: Culicidae)  Ian Cooper

 

We don’t know what this is, but we presume it is an immature stage (nymph) of some bug:

Aziza Cooper writes:  Today, June 25, at Layritz Park there were two Western Tiger Swallowtails, one Cabbage White and two Lorquin’s Admirals. At Viaduct Flats there was one Essex Skipper.

   Marie O’Shaughnessy writes:  Outerbridge Park tour Sunday June 23rd 2024, for butterflies and dragonflies.  Butterflies were:
1 Western Tiger Swallowtail
2 Cabbage Whites

  Dragonflies were:
1 male Cardinal Meadowhawk.

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.

 

Probably Blue-eyed Darner Rhionaeschna multicolor (Odo.: Aeshnidae)

Marie photographed this Painted Lady at Mount Tolmie:

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.

Marie O’Shaughnessy photographed this immature male meadowhawk at Panama Flats of June 22.  Because its colours are not yet fully developed, it is hard to be certain of its exact identity.

Aziza Cooper photographed this beetle at the railroad tracks near Goldstream campground on June 20.  Scott Gilmore makes the tentative suggestion: Toxoleptura vexatrix

 

Probably Toxoleptura vexatrix  (Col.: Cerambycidae)  Aziza Cooper

 

She also photographed these beetles (below) in the same area.  Scoot Gilmore identified them for us as Bruchidius villosus.   If you Google this name, you will find a lot of interesting information about this beetle.

Jeff Gaskin writes:  Both yesterday, June 22, and today I’ve been seeing Common Green Darners in the city.  Yesterday I was at UVic and there were three of them in a grassy field near Gordon Head Road and McKenzie Avenue. Today I saw at least two of them at Cuthbert Holmes Park.  This makes me feel that there are a number of them around as compared to other years.  Jeremy Tatum adds:  I was at Swan Lake for only a few minutes today, but I saw one there.  Also at Swan Lake there were lots and lots of Lorquin’s Admirals, all new and fresh.  I found a caterpillar of a Western Spring Azure on the Ocean Spray.

Aziza Cooper writes:  At Mount Tolmie about 6 pm, there was one Red Admiral, two Painted Ladies by the Jeffrey Pine, and one Painted Lady on the reservoir.

   Here are two dipterans photographed by Ian Cooper.  We *think* we know what they are, but we can’t be quite certain, and we would welcome opinions by knowledgeable viewers.  We think the little yellow fly is probably a vinegar fly (Drosophilidae), but we can’t be quite certain.  We think the other is probably a nonbiting midge (Chironomidae), but it might possibly be a mosquito (Culicidae).
