   Another Friendly Reminder.  Contributors please do try to remember that it is a huge help if you


     1. Send photographs as an attachment, not in the body of the message.

     2. Say where the animal was.  (Not “in my back yard” – I don’t know where your back yard is!)

     3. Say when you saw it.  (Not “yesterday”.  The date, please!


  Thank you all!


   Scott Gilmore sends from Lantzville photographs of a prominent moth and a ladybird beetle (the latter found by his son), both of which were lifers for him.  To the uninitiated, the moth may look like just another of the hordes of featureless grey or brown noctuids.  But to the enthusiast, it’s an exciting moth.  Not a noctuid at all, but a notodontid, an exciting family known as “prominents”.  The caterpillar of Gluphisia severa feeds on Populus.  The ladybird is the Two-spotted Ladybird.

   Rebecca Reader-Lee writes that on April 15 Emma found the spider shown below on the floor inside the house.  Robb Bennett tells us that it is either Coriarachne brunneipes, or Bassaniana utahensis.  He writes that they both pretty much look the same at the “whole spider” scale.

   Annie Pang sends a photograph of a bee fly, Bombylius sp.  This is a large genus, but the fly shown seems to resemble closely a female B. major.  They throw their eggs down the holes of mining bees.

Hi Butterfly Counters.

This weekend marks the beginning of the 2016 Butterfly Count season. As always, the count period is from the third Saturday to the fourth Sunday – nine days, or April 16-24 this year. You can submit a count anytime over this period, and you can do more than one count, just use a separate form for each count. In the case of repeat counts or more than one person counting an area, I will take the highest count for each species.

Please use the form at on the Victoria Natural History Society website.


The count area is the same as the Christmas Bird Count circle. For butterfly identification there are numerous internet sites, but most or all Victoria species are listed on E-Fauna. If you select by photographer, all the photos under James Miskelly’s name are of Victoria species:,%20james&specrep=0


I am now acting as coordinator of the count, as Aziza is taking a break. Please let me know if you want to be removed from this list. If you know of anyone who would like to be added, please ask them to send me their email address.


If you would like a suggestion for an area to count, please send me an email.

In addition to the counts, a monthly butterfly walk is held on the first Sunday of each month – May 1st,  is the next walk. We start at the summit of Mount Tolmie at 1pm, and decide where to go from there. The walk will be cancelled if the weather is cool or rainy.

Thank-you for submitting your sightings and happy counting!

   Some more wonderful pictures from the Highlands District from the last few days contributed by Thomas Barbin.  First, a leafhopper bug – the Blue-green Sharpshooter Hordnia atropunctata:

Two images of a sawfly, probably Tenthredinidae, not only because this is the largest sawfly family, but because the other families usually have rather distinctive antennae.   I am reminded that this site is perpetually in need of someone who can help with Hymenoptera identification, so, if that is you, please let us know!

If you managed to get past that one, prepare for the last two – jumping spiders.  Robb Bennett suggest they may both possibly be Evarcha proszynskii, but he says that he can’t be completely sure.

Time for something a little more gentle, I think.   Here is a Moss’s Elfin, photographed by Jeremy Gatten.

And a caterpillar that Jeremy Tatum found on Snowberry at Swan Lake on April 12:

Jeremy Tatum writes:  The moth below was on the wall of my Saanich apartment a week or so ago.  Eric LaGasa suggests that it might be Agonopterix fusciterminella, though it would need dissection to confirm.

The moth below, identified by Eric LaGasa as Argyrotaenia franciscana, from Blenkinsop Lake, was reared from Oemleria cerasiformis.

   Rebecca Reader-Lee sends photographs of four moths from North Highlands, April 11.  All are members of notoriously tricky pairs, and Jeremy Tatum is grateful to Jeremy Gatten for help with the identifications.  It turned out that we agreed on the identification of the first three – Feralia comstocki, Orthosia transparens, and Hypena californica.  The fourth is a not-quite-pristine-fresh example of one or other of the very tricky pair Triphosa haesitata / Coryphista meadii, and it turned out that Jeremy opted for one of them and Jeremy opted for the other!  So – if anyone else would like to throw his or her hat into the fray and say (with reasons!) which of the two you think it probably is – do please let us know!

Is it Coryphista meadii (Lep.: Geometridae)?

Or is it Triphosa haesitata (Lep.: Geometridae)?

Rebecca Reader-Lee

We haesitate to say.



The next moth, found on April 10 by John Costello in Grant Park, where the path crosses Amblewood Drive, near the top of the Cordova Ridge, and photographed by Chantal Jacques, is a bit easier to identify!  It is a female Ceanothus Silk Moth Hyalophora euryalus.

   Jody Wells sends us a bit of a challenge.  What is this on the eye of a swan?

Jeremy Tatum writes:  At first glance it looked to me a bit like a collembolan, but in view of its habitat (!), it is almost certainly a biting louse, also known as chewing louse, also known as bird louse (Class Insecta,  Order Phthiraptera, probable Family Philopteridae).  And, for interest, this is not the first time we have had a phthirapteran on this site!  We had one on a Northern Saw-whet Owl on December 4, 2011.

In addition to the challenge of identifying the louse, there is also the challenge of identifying the swan!  The picture was taken at Esquimalt Lagoon, where a Trumpeter Swan and a Tundra Swan have been together in close company for some months.  There is no doubt that the louse is on the head of the Tundra Swan, and the swan in the background is the Trumpeter Swan.

   And, in case any of you were wondering what a “collembolan” is (see previous paragraph) here is an absolutely remarkable photograph of a collembolan photographed by Thomas Barbin in the Highlands District On April 7, and this is the first collembolan to feature on this site.  Collembolans, or springtails, are tiny, tiny animals, many of which are found in the soil or in the forest duff.  This one is a globular springtail Ptenothrix maculosa.  You’ll notice that I wrote “animal” rather than “insect”.  Springtails were at one time classified as insects, but, as we all know, taxonomy forever changes!  It is my understanding that the Phylum Arthropoda now includes a Subphylum Hexapoda, and the Hexapoda contains two Classes, Insecta and Entognatha.  So, springtails are no longer insects – they are entognaths!  And globular springtails belong to the Order Symphypleona, and the one illustrated below is in the Family Dicyrtomidae.  At least I think I’ve got that right!   More pictures from Thomas Barbin tomorrow.  Jeremy Tatum.
