   Jeremy Tatum writes:  Most pug caterpillars feed on fltowers.  Here is one in the flower head of the dogwood Cornus stolonifera.  The adult moth ecloded (emerged) on June 13 (see posting of that date) and enabled Libby Avis to identify it as Eupithecia misturata.

   Marie O’Shaughnessy writes:  This beautiful Western Tiger Swallowtail was photographed at Loon Bay, May 28th, while the tide was out. It appeared to be ingesting the salt water between the rocks on the mud-flats.

   Jeff Gaskin writes:  Yesterday, May 28, around 6:15 p.m. in the wind there was a West Coast Lady alongside the road on Mount Tolmie.  It was not too far from the concrete reservoir.

   A plea from the Moderator.   We are getting lots of exciting contributions at this time of year, which is a wonderful situation to be in – but of course the volume of contributions does make for a little bit of work.  This plea is not aimed at anyone in particular and it may sound like the Pontifications of a Pompous Professor to first-year students.  All the same it would be an immense help to the Moderator if contributors could spend just a minute or so proofreading the text of their contributions for spelling, capitalization of proper names, no abbreviations please, and little details like that.  I know that it takes a little extra to do it, but after all,  if you don’t do it, the Moderator has to – for all entries!   When a contribution comes in with all the text perfected, all I have to do is a quick copy-n-paste, and it is done in a second.  Otherwise it takes a few minutes per entry, and when there are half-a-dozen contributions, that begins to mount up.  But believe me – I very much appreciate all contributions, whether perfectly composed or not!

   Jeff Gaskin writes:  Today, May 28, I saw my first of the year Lorquin’s Admirals.  One was in Gorge Park, and the other flew through my Mom’s backyard on Wascana Street.  Kirsten Mills told me she saw a Lorquin’s Admiral on Saturday May 26, behind the Swan Lake nature house, so there seem to be a few of them around already.

  Bryan Gates writes:  I found this caterpillar today, May 28, 2018, in my yard at Saratoga Beach, Black Creek, B.C.  (near the Oyster River).

   Jeremy Tatum writes:  On May 17 morning I posted pictures of three unidentified caterpillars, with speculation as to what they were.  The one I speculated as Choristoneura rosaceana was harbouring hymenopterous (Braconidae?) parasitoids, and it died, so we shall never know.  We probably shan’t see the adult of the geometrid caterpillar until early next year.  The adult moth from the caterpillar that was speculated to be Hedya nubiferana emerged today, and it turned out indeed to be that species.  Photograph below.

     Jeremy continues:  Today I saw several  (I didn’t count) Field Crescents at Eddy’s storage.  For those who don’t know where Eddy’s Storage is and who would like to see this butterfly, it is on the north side of Stelly’s Cross Road, a few tens of yards to the west of West Saanich Road.

    Jeremy continues:  I saw my first Mourning Cloak since 2016 at Quick’s Bottom today.  Quick’s Bottom is reached from Markham Street in Saanich.

    Kirsten Mills writes:  Here are some butterflies from Goldstream Heights this morning. I saw 6 Pale Tiger Swallowtails,  3 Western Tiger Swallowtails and 1 Anise Swallowtail. Also 1 Western Brown Elfin,  6 Cedar Hairstreaks and 5 Western Spring Azures.

   Marie O’Shaughnessy also found a Cedar Hairstreak, also at Goldstream Heights.  Marie writes: I was with Kirsten and I believe she is sending you some pics to ID too of this butterfly. There were many up there today. Feasting on daisy nectar.

   Jeremy Tatum writes:  The Astronomy Conference is now over, so Invert Alert is now back to normal!   Thanks for your patience last week.

   Scott Gilmore sends some interesting photographs from Lantzville, May 26:

   First, a beetle hitchhiking on a bee. The beetle is Antherophagus ochraceus. I am not sure about the bee but I am seeking an identification. The beetle develops/ lives in bee hives. I have seen the beetle on thimbleberry flowers… maybe waiting for a lift!

   There are also pictures of a fly –  a male and female Dolichopus. The male has large pads on the front feet.

   Last is a water strider, Aquarius remigis.

   Correction:  Jeremy Tatum writes:  On May 25 there was reference to the yellow colour on T2 of Annie Pang’s bee photograph.  I suggested that T2 referred to the second thoracic segment, which is the normal notation used to describe a moth caterpillar.  This was wrong.  Thanks to Jeremy Gatten who pointed out that, in the description of adult insects such as bees and wasps, the notation has a quite different meaning. The abdominal segments of these insects are made of two plates stapled together; the upper plate is a tergite, the lower plate is a sternite.  The T refers to the tergite, and the 2 refers to the second abdominal  segment.  I checked with Lincoln Best, and he confirms that it was this latter interpretation that he intended, which is apparently usual with adult insects. 

   How you pronounce tergite would occupy another small essay!

   When I was editor of a scientific journal I had a strict rule that all abbreviations must be defined on first mention – no exceptions, no ifs, ans or buts.  No author was allowed to assume that everyone understood what an abbreviation was intended to mean, or that a particular abbreviation was “standard” and need not be defined.   (And by the way, I meant “ans” and not “ands”!)
