   Nathan Fisk sends a photograph of a Cedar Hairstreak (the first that Invert Alert has heard of this year) from Beacon Hill Park  –  you don’t have to go out into the wilderness to find interesting butterflies!

   Rosemary Jorna sends a photograph of a beetle found under a rock in her Kemp Lake area garden, May 7.  Charlene Wood writes:  This is the Greater Night-stalking Tiger Beetle Omus dejeanii. Primitive, nocturnal, wingless, and distributed from southwestern BC to southwestern Oregon. A nice sight! Similar to the threatened Omus audouini, but separated by dejeanii having larger punctures on the elytra, pronotum constricted behind (rather than parallel), and pronotum with a depression on the midline.

   Jeremy Tatum writes:  I wonder if the Mount Tolmie hill-topping season has at last arrived.  At 4:30 this afternoon I went there, and there were two Painted Ladies near the Jeffery Pine, and a Painted Lady and a Red Admiral on the reservoir.

May Butterfly Walk

Gordon Hart

 

   We had beautiful weather for the second butterfly walk of 2017 . Eleven observers saw three species at Mount Tolmie: two Western Spring Azures, two Cabbage Whites, and a Propertius Duskywing that circled around close enough for everyone to get good looks.

 

Eight people continued on to Munn Road powerlines and the ponds by the Pike Lake substation where we saw five species of butterfly: about 10 Western Spring Azures, four Sara Orangetips, a presumed Painted Lady fly-by, and a Western Brown Elfin perched on salal. We also saw a fresh male Spiny Baskettail Epitheca spinigera dragonfly, and a pink lady beetle.

[Jeremy Tatum writes: The beetle was later identified for us by Charlene Wood as a colour variety of Calvia quatuordecimguttata, known as the Cream-spotted Ladybird.  It is very variable in colour, and some varieties (not this one) actually have cream spots!  Latin scholars will note that the specific name means 14-spotted – but that there should be two ts in quattuor. However,the rules of taxonomy don’t allow you to change the spelling of a name once it has been conferred on an organism by its original describer, even if he/she spelled it wrongly.  In fact I believe Linnaeus originally spelled it 14-guttata, but numerals are no longer allowed.]

    Five people travelled a bit further to Gordon and Anne-Marie’s property, where Rick Schortinghuis got a glimpse of an unidentified elfin and two commas. We were able to find one of the commas, a Green Comma, Polygonia faunus, my first of the year.

 

Finally, the three members who returned early to Mount Tolmie saw a Painted Lady near the Jeffery Pine, so that species can safely be included in the total of seven species.

   Annie Pang sends a photograph of a pair of Harmonia axyridis not wasting any time.  This is a very variable species of ladybird, but the black W on the pronotum identifies it as this species.

Mike Yip writes:  Butterflies are still scarce around Nanoose Bay, but I did see a few Sara Orangetips, Western Spring Azures, and Western Brown Elfins. A surprise find was a Hoary (“Zephyr”) Comma at Cross Road – they are usually at higher elevations and Cross Road is probably less than 50 m.

   Annie Pang sends two spider pictures, and we thank Robb Bennett for his comments and identifications.

 

Of the first picture, Robb comments: Young orb-weavers / garden spiders, starting to disperse.  They have overwintered in an egg case hidden away somewhere last fall by their dear departed mother.  Likely your spiders are young of Araneus diadematus – a species introduced years ago from Europe and one of the most common orb-weavers in southeastern BC.  Could also be one of our native orb weavers — I can’t tell them apart as juveniles.

 

Of the second, he comments:  That’s another introduced species — a female [you can clearly see her epigynum (mating apparatus) on her abdomen] giant house spider.  Now Eratigena atrica, formerly Tegenaria duellica.

Jeremy Tatum comments:  Unusual foodplant.  Not sure what it is – Thimbleberry, maybe – but the caterpillar seems to be enjoying it anyway.  Usual foodplant is Douglas Fir.

  Gordon Hart writes:  On May 4 I thought I would check the Pike Lake Substation pond area past the yellow gate. There were lots of  Western Spring Azures, at least 20,  two Sara Orangetips, a Painted Lady, and a fresh Two-banded Grizzled Skipper nectaring on wild strawberry.  [Jeremy comments:  Interesting – that’s also the larval foodplant.]  A Propertius Duskywing flew off before I had a proper look I also attach a picture of a click beetle I saw at Francis/King Park.

   Reminder:  Monthly Butterfly Walk tomorrow.  Meet at the top of Mount Tolmie, 1:00 pm. Sunday May 7.  All welcome.  For details, see the May 4 posting.

 

Jeremy Tatum writes:  I have been visited by very few moths at my Saanich apartment this year, and I have been feeling neglected.  This morning, however, I was at last favoured with a visit by a moth – the Common Clothes Moth Tineola bisselliella.

   I went up Bear Hill today, the centre of the Gypsy Moth infestation, but I didn’t see any in any of its stages. And I saw only one butterfly – a lone Western Spring Azure.

 

   Ken Vaughan writes:  I went to the Beaver Lake Retriever Ponds today, with high hopes of finding some odes. I did. I believe the first photo is a male Pacific Forktail, and the second is a female, although I’m less sure of it than the first photo.  [Thanks to Rob Cannings, who confirms that this is indeed a teneral female Pacific Forktail.]

Val George writes:  On Thursday, May 4, I was in Tofino.  The 22 ºC weather produced for me the first significant display of butterflies I’ve seen this year:  about a dozen Western Brown Elfins (photo),  2 Western Pine Elfins (photo), a Mourning Cloak, and 3 Cabbage Whites.  On the way home I photographed a White-ribboned Carpet Moth Mesoleuca gratulata at Somenos Marsh in Duncan.
