  Jeremy Tatum writes:  Today Bill Savale and I walked along the railway line north of Cowichan Station.  There were a few Margined Whites Pieris marginalis  there, nectaring, as they often do, on Herb Robert.  There was a lot of Nasturtium in the adjacent ditch, and also a lot of Hesperis at the side of the ditch.  I think Nasturtium is probably the favoured larval foodplant, though in the past I have found and successfully reared them on Hesperis.  The butterflies we looked at were completely immaculate white above.  They are often completely white underneath, too, but, in the one we had a good look at, the veins on the underside were boldly marked in grey, looking very like the European Green-veined White Pieris napi.   The immature stages of the two seem to be indistinguishable, and a case could be made for lumping them both under the name Pieris napi.

  The flight of the Margined White is lighter and more floatier than that of the Cabbage White.  Not so light as that of the Pine White, but something in between.

    There were also a few Western Spring Azures there, and I saw my first Satyr Comma of the year.

   Jeremy Tatum writes:  I spent three hours this afternoon counting butterflies along the Panhandle Trail at Munn Road.  Two dozen or so Western Spring Azures, a few Cabbage Whites and Sara Orangetips, and one each of Moss’s Elfin, Cedar and Grey Hairstreaks, Painted Lady and Propertius Duskywing.  (Also a Barred Owl, Hutton’s and Cassin’s Vireos, and lots of McGillivray’s and other Warblers.)  Among the day-flying geometrid moths, unfortunately I didn’t see any Epirrhoe plebeculata, though I saw a few Mesoleuca gratulata and several Leptostales rubromarginaria.  I watched the latter for a while in case I was lucky to see one ovipositing, but I had to move on and get on with the Butterfly Count.  I’m sure if someone went there with the sole purpose of watching these tiny reddish moths for an hour or so, he or she would sooner or later advance the boundaries of knowledge by finding out what plants they lay their eggs on.

   I visited Mount Tolmie at 6:10 pm.  There was one Painted Lady basking on the reservoir, and a further three cavorting around near the Jeffery Pine.

   Jeff Gaskin writes:  Today I found a total of at least 8 Silvery Blues amongst the lupines at their usual spot at the Island Highway’s Colwood exit, right next to the Galloping Goose Trail.

   Judy Spearing sends a photograph of a caterpillar of the Silver-spotted Tiger Moth on the Ocean Spray in her garden (Bow Park area).  The usual foodplant is Douglas Fir, but they are by no means restricted to that plant, as recent photographs sent to this site have shown:  Today, Ocean Spray. May 16, Western Red Cedar.  May 7, Thimbleberry.

Hello Butterfly Counters,

The May count runs nine days from the third Saturday, May 20, to the fourth Sunday, May 28. 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 https://www.vicnhs.bc.ca/?p=33 on the Victoria Natural History Society website .

The count area is the same as the Christmas Bird Count circle (attached). 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. Here is the link: http://linnet.geog.ubc.ca/efauna/photoGallery/Gallery.aspx?gr=showall&pid=175&photographer=miskelly,%20james&specrep=0

If you would like a suggestion for an area to count, please send me an email. The weather is finally looking much better this month, so we can hope for a good count.

In addition to the counts, a monthly butterfly walk is held on the first Sunday of each month – the next walk will be on June 4th. We start at the summit of Mount Tolmie at 1pm, and decide where to go from there. I will send out another reminder that week.

Thank-you for submitting your sightings and happy counting!

Jeremy Tatum writes:  One Painted Lady near the Mount Tolmie Jeffery Pine at 4:00 pm today, but nothing on the reservoir.  Warm and sunny afternoon – but is it too late for that now?

Dar Churcher sends a photograph of a Zebra Spider with a hapless mayfly, Colwood, April 19.  And Mik Yip sends a photograph of a caddisfly from Nanoose Bay, May 17. We have had only a very few representatives from these Orders (Ephemeroptera, Trichoptera) so far on this site.

   Jeremy Tatum sends photographs from his Saanich apartment of a Common Emerald moth, and a micro moth, probably Olethreutes glaciana.  The Common Emerald, like that other European moth the Large Yellow Underwing, is now a very common moth indeed in Victoria.  The micro was found as a caterpillar at Panama Flats, feeding on Snowberry.
