   Re the Cakile species on which are seen Cabbage White eggs on Jochen Moehr’s June 26 photographs, here’s what Nathan Fisk writes:  Seeing the leaves would help but this photo shows “silicles usually expanded at the joints into projecting wings” – ‎which would put this as C. maritima. It’d be good to see the leaves before I stake my reputation on that ID.  Jeremy Tatum writes:  Thank you, Nathan.  That’s good enough.  I suspect the butterfly isn’t very particular as to which species of Cakile she lays her eggs on.  Cabbage Whites choose a wide variety of Brassicaceae – not just our garden cabbages!

   No response yet for our appeal for an opinion on Peter Boon’s commas on Mount Becher (June 25 entry), but Peter has managed to get a good photograph of the underside, and I think most of us would now agree that the butterfly is the Hoary (“Zephyr”) Comma Polygonia gracilis zephyrus (which Guppy and Shepard list as a full species). [Added later:  Mike Yip concurs.]

Has anyone seen any Satyr Commas recently?  This used to be one of our commonest butterflies, but it now seems to have disappeared.

   Jeremy Tatum writes:  A few Painted Ladies, Red Admirals, Lorquin’s Admirals, Western Tiger Swallowtails and one West Coast Lady on the Mount Tolmie reservoir at 6:00 p.m. tonight.  On looking closely at the West Coast Lady, I became fairly sure that it may well have been the same individual that Val George photographed a few days ago (see June 16 posting).  I find that I can pick out the West Coast Lady in flight – the orange seems a slightly different shade than the orange of the Painted Ladies.

 

Ken Vaughan writes:  I was out to Beaver Lake on Saturday morning, and I took some photographs.

Banasa dimiata (Hem.: Pentatomidae)  Ken Vaughan

Jeremy Tatum comments:  For those still a little uncertain about beetles and bugs, Banasa dimiata is about as typical a bug as you can get.  The tip of the pronotum in dimiata is usually yellow.  This introduces a note of uncertainty into the identification.  Maybe it is another species.  If any expert out there can help, please let us know.  Ken sees a green chalice on the back.  I see it, too.  Can you?

 

Ken has chosen to use the name “Red Admirable” for Vanessa atalanta.  Although the name used most often these days is Red Admiral, it has been suggested that “Admiral” was originally “Admirable”, and it has lost a syllable along the way.  It has been advocated that we should restrict the name “Admiral” to the Limenitis  group.  It is true that Moses Harris, in his 1840 book The Aurelian, called atalanta “The Admirable”.  However, if we go back still further, to the seventeenth century, James Petiver, who introduced many of the English names for butterflies, called it the Red Admiral – so it looks as though Harris added a syllable, and today’s “Admiral” agrees with Petiver’s original name.

 

 

Rosemary Jorna photographed the beetle below at Jordan River on June 22.  There are more species of beetle than of any other Order in the animal Kingdom – which means, unfortunately, that we cannot always identify each one with certainty.  However, thanks to Charlene Wood, we know at least the Family of this one – Bupestridae.

Annie Pang photographed a bee-like robber fly in Gorge Park, June 25.  Annie is showing us what a great variety of creatures are to be found even in a rather urban park, without trekking far into the wilderness.  Rob Cannings comments:  This is a female Laphria, either L. asturina or L. fernaldi. I believe there is a good possibility that both these names refer to the same species and any small colour differences used in keys to separate them are insignificant. Anyway, that’s the identification situation concerning the common southern BC Laphria with red hairs on the abdomen!

Rosemary Jorna writes:  Sid found this spider while cleaning the garage today, June 25, Kemp Lake Area.   Sean McCann writes:  This is Steatoda grossa, the False Black Widow.  Very common in places like garages!

Jochen Moehr writes: I watched a P. rapae busily depositing eggs on some brassicaceous plants on Taylor Beach, close to the cliff drop-off among the drift wood.  I also took some pictures of the plants.  They clearly are some kind of Brassicaceae, but I was unable to get clues to the identification.  Jeremy Tatum responds:  Cabbage Whites quite often lay their eggs on these plants on the seashore.  The plant is Sea Rocket Cakile sp., but it will need a better botanist than I to say whether it is the native American Sea Rocket C. edentula or the European Sea Rocket C. maritima.  I believe both occur here.  If some botanist can help us, please do so!  (More detailed pics of the plant are available.)

Jeremy Tatum writes:  Peter Boon photographed an interesting moth in the Nanaimo River estuary on June 23.   Not only could I not identify it, but it turns out that it was one that I hadn’t even heard of!  Libby Avis identified it for us as Leucania dia – and she reports that she had also found one a few days ago in Port Alberni.  This moth was until recently regarded as a subspecies of another species of wainscot moth; it was named a full species only a few years ago, in 2010.

   Peter Boon writes:  During a hike up Mount Becher today I found 4-5 commas patrolling the mid-lower slope trails.  One seemed to like perching on my hat, so I took it off to snap a photo or two. Lower down on the old ski runs I found a fresh Western Meadow Fritillary. Also seen on the lower slopes was a Pale Tiger Swallowtail.

 

   Butterfly enthusiasts are asked to look carefully at Peter’s comma photographs and to let us know which species you think it is.  Please do let us know what you think, and why. [Added later:  Problem solved.  See June 27 entry.]

   Jochen Moehr writes:  I continue to enjoy the drive up to our new Metchosin property.  I always encounter up to four Papilios and some Pieris rapae.  Today I saw my first Lorquin’s Admiral of the year.  And I was able to take pictures of this Papilio eurymedon.

   Aziza Cooper writes:  Yesterday, June 23, about 4 pm, I went to Government House on Rockland Street. The usual hotspot is a lawn in an opening in the Douglas firs due east of the big main house.  I was enthralled to see a constant flurry of Western Tiger Swallowtails chasing around the clearing with up to six dancing together up to the treetops. I estimated 15 individuals circulating around the area. I watched them for 20 minutes or more admiring their constant motion and numbers.

 

   Also there were one each of Pale Tiger Swallowtail, Cabbage White, Red Admiral and Lorquin’s Admiral.  At the herb garden west of the big house, there was an Anise Swallowtail and a Lorquin’s Admiral, and six other Cabbage White butterflies around the grounds.

 

   The swallowtail show is really worth a visit!

 

   Jeremy Tatum writes:  The tiger swallowtails were putting on a good show, too, on Mount Tolmie last night.  I’m sure the scientists will differ, but I got the strong impression that they were cavorting around and chasing each other for the pure joy of it.
