   Jeremy Tatum writes:  Here is the pug moth that came from the caterpillar shown on dogwood on May 29.   Thanks to Libby Avis for helping with the identification as Eupithecia misturata.

  Jeremy Tatum writes:  I had two tortricid moths emerge from their pupae recently.  They looked quite different, not only in their markings, but in their size, the female being much larger.  However, Justin Dombrowskie kindly identified them for us as a male and female Archips rosana.  The caterpillars had been found on Cornus stolonifera (the female) and on Rubus discolor (the male).

   Jeremy continues:  David Harris and I went to Island View Beach today, where David was treated to a sight of several pristine fresh Lorquin’s Admirals.  Then we went to the fields inland from Island View Beach, hoping to find Ringlets  (also known as Large Heaths).   I am embarrassed to say I got hopelessly and utterly lost!  It is a much larger area back there than I had ever realized.  After wandering randomly for a long time, we eventually met someone and we had to ask the way.   Anyway, it was worth it, because we saw several Ringlets and a Purplish Copper.  We also found caterpillars of an Essex (European) Skipper and a Garden Tiger Moth (both of which David could have found in Sussex!).  The caterpillar of the Garden Tiger is the original Woolly Bear, the latter feeding upon Yellow Honeysuckle.  I haven’t seen one here for a few years, and it permitted only a not-very-good photograph, shown below:

  Invert Alert received three photographs of beetles yesterday.  We are grateful to Scott Gilmore for identifying them for us at genus level.

   Val George writes:  Yesterday afternoon, June 11, there was a bonanza of butterflies on and in the immediate vicinity of the Mount Tolmie reservoir: at least 5 Western Tiger Swallowtails, 3 Pale Swallowtails, 2 Anise Swallowtails, at least 3 Painted Ladies, 4 Lorquin’s Admirals, and one Propertius Duskywing.

   Jeremy Tatum writes:  And at 6:30 p.m. I took David Harris, straight off the flight from England, to Mount Tolmie, and we saw nothing there!   Well, almost nothing.  Just when we were about to give up in total disappointment David spotted a rather worn Painted Lady (same species as he sees in England) near the Jeffery Pine.  David cheerfully remarked that it was exciting because it was the first one he had seen this year.  Then we caught a brief glimpse of a Lorquin’s Admiral disappearing over a bush.  We visited the reservoir again this morning – and saw nothing!  Later on today, we had more success – a Cabbage White at UVic, and a brief glimpse from the car of a distant Western Tiger Swallowtail.  We found three caterpillars – a Western Spring Azure on Ocean Spray on Mount Douglas, a lost Silver-spotted Tiger Moth at UVic (we put it on a nearby Grand Fir), and a Euthyatira pudens on Cornus stolonifera at UVic.

   Sonia Voicescu writes:  I was doing my bi-monthly count for my RNS project at Rithet’s Bog and I saw quite a few butterflies yesterday! Specifically:  12 Lorquin’s Admirals, 19 Ringlets (Large Heath), 1 Mourning Cloak, 7 Western Tiger Swallowtails, 4 Cabbage Whites.  Attached are some pictures of the Lorquin’s Admiral and the Ringlet (which has had a rough time judging by its mangled wings).

   Jeremy Tatum writes:  The Lorquin’s Admiral shown below came from the caterpillar and chrysalis shown in various stages on May 30, 31, June 1.  I released it this morning on the Philadelphus at the entrance to the Mount Tolmie reservoir.  There were at least another four Lorquin’s Admirals on the same bush, all in pristine fresh condition.

   Nathan Fisk writes (June 10):  Wonderful day to be a naturalist! A good break in the clouds and wind for all the inverts to emerge. Many Lorquin’s Admirals, Tiger and Anise swallowtails, Propertius Duskywing (attached), Eight-spotted Skimmer, blue damselflies, a “dusty” blue dragonfly that I’ve not seen before,  ‎ and abundant Bombus vosnesenskii, melanopygus and bifarius feeding on Snowberry and Himalayan Blackberry.

   Liam Singh sends photographs of two caterpillars from Mount Tolmie.  Jeremy Tatum writes:  I believe the first is Tetracis sp.   It may be T. jubararia, though I have never seen one that colour, so there is a possibility that it is a different species.

    Liam’s next photograph is the same species of noctuid caterpillar that Nathan Fisk showed on June 1.  Jeremy Tatum writes:  I have seen this caterpillar several times in previous years, but I have never found out what it is.  I am very anxious to find out.  If any viewer finds one like this, please retain it for me.

   Also from Moun Tolmie, writes Liam Singh:  One highlight was being able to see 11 adult Oak Treehoppers! They were along the North side in a small Garry Oak.

    (In case you are wondering where June 9 is, there were no reports yesterday, so no June 9 posting.)

    Jeremy Tatum writes:  Here is a caterpillar of Egira crucialis.  The adult moths E. crucialis and E. simplex look so similar that it is often difficult to tell them apart.  So – are they really different species?  I have a theory that if two very similar moths are really different species, their caterpillars will be quite different.  Here is a case in point.  The final instar caterpillars of crucialis and simplex are so different that they are obviously quite distinct species.  On the other hand the adults and the caterpillars and chrysalides of  Pieris napi and P. marginalis are as indistinguishable as the adults.

   Why is the caterpillar of Egira crucialis white?  Doesn’t this make it very visible and vulnerable?  The answer is no – the white caterpillar hides inside the equally white panicles of Ocean Spray flowers.  This one is on its way there now.

   Aziza Cooper writes:   Yesterday, June 9, at Jordan River, dozens of Rufous Hummingbirds were competing with many bees at an array of nine feeders near the former town.  I’m not sure this shows much detail of the bees, but the pile-up of bees on the feeder is impressive.

  We don’t know the exact species of the next fly, but anyone who rears caterpillars will recognize the bristly abdomen and will know that this is a dreaded tachinid fly.

   Jeremy Tatum writes:  Thanks to several people for keeping me informed about recent butterfly sightings.  This will help me in finding them for my Sussex visitor.  Kirsten Mills writes that she has seen a Lorquin’s Admiral at Island View Beach (photograph below), and that there is a group of Cedar Hairstreaks on daisies along the second small path past the gate at the end of Goldstream Heights Drive.  Also there, a Pale Tiger Swallowtail.

      Gordon Hart has both tiger swallowtails at his Highlands property, as well as a Cedar Hairstreak.

     Aziza Cooper writes:  On Saturday, June 2, at the reservoir on Mount Tolmie, there was a Grey Hairstreak with others which I noted previously.   On Wednesday June 5, on the west slope of Mount Douglas, there was a Cinnabar Moth, one tattered Western Spring Azure, a Western Tiger Swallowtail, a Pale Tiger Swallowtail and a Lorquin’s Admiral.

   We sometimes have difficulty in distinguishing between the several species of Bombus (bumble bees).  Apparently we are not the only ones having this difficulty – evidently the bees don’t always get it right.  The photograph below, obtained by Liz Sparkes in Parksville in August 2017, shows a B. vosnesenskii  and a B. occidentalis in copula. Although the date does not strictly qualify for Invertebrate “Alert”, we thought the photograph was sufficiently interesting to make an exception.
