   Ian Cooper photographed this tiny wasp at his home in Victoria.  There are hundreds, if not thousands, of parasitoidal wasps in the families Ichneumonidae,  Braconidae, and some related families.  Identification is a challenge, but, writes Jeremy Tatum, I agree with Ian that this is a braconid, and in the subfamily Microgastrinae:

Ian also photographed this dead Antrodiaetus pacificus.  Ian would like to acquire a suitable microscope that would enable him to make scierntifically valuable drawings of some of the creatures that he finds.  Suggestions, anyone?

Jeremy Tatum writes:  Several contributors agree with my comments on May 29 about the paucity of butterflies.  However, there have been a few moments of sunshine in the last few days, and a very few welcome butterflies have been seen on Mount Tolmie, Mount Douglas and Outerbridge Park.   Forgive me if I omit some of the details of time and place and other details  – got a bit of a cold and am taking advantage of it by spending some delicious hours in bed!

How do you tell the difference between a Pale Tiger Swallowtail and a Western Tiger Swallowtail?  Well, in the Western, the black stripes are narrower than the yellow stripes;  in the Pale, the black stripes are broader than the yellow.  So, which is the one below?  See the problem?  Well, I’m putting this down as a Western.  Let me know if you disagree.

And how do you tell the difference between a Painted Lady and an American Lady?  Well, in the Painted Lady, the white patch near the apex is blunt.  In the American Lady, it is pointy, and it points to small white spot.  So, which is the one below?  See the problem?  Well, I’m putting this down as a Painted Lady.  Let me know if you disagree.

The one below is unambiguously a Painted Lady:

VNHS Butterfly Walk on Sunday, June 2.
Message from Gordon Hart

This is a reminder for the VNHS Butterfly Walk on Sunday, June 2.

We will meet at the Mount Tolmie summit by the reservoir, at 1.00 p.m. You can park in the parking lot there, or in the large lot north of the summit. After a look around the summit, we will decide on a destination from there.

As mentioned in the calendar description, this field trip is weather-dependent as it needs to be sunny and warm to make it worthwhile. Cancellations or special instructions will be posted on this site or the calendar (https://www.vicnhs.bc.ca/?page_id=1518 ) closer to the date.

Hoping the weather cooperates!

Gordon Hart

   No Butterflies. There have been no butterflies reported to this site since May 23.  Is this a real lack of butterflies, or just a lack of reporting?   I have not been out a great deal, writes Jeremy Tatum, though I haven’t seen any myself.  What are others finding?

   Jeremy Tatum writes:  During the Uplands Park Insect Bioblitz on May 12, I found a small caterpillar on dogwood.  It has now transformed into an adult moth, kindly identified by Dr Jason Dombroskie as Pandemis cerasana, shown below.
