   Rosemary Jorna writes:  We took a walk at the Sooke Potholes today  I was disappointed by the complete lack of butterflies. We  came down to our favourite beach and there were a dozen or more Swallowtails flying about and puddling.   There were about 4 Western Tiger Swallowtails and 8 or more Pale Tiger Swallowtails – 3 to 8 puddling and the rest flying overland around the pool and beach.  We watched them for about a half hour.  They were gradually losing interest in that patch of wet sand.

   Identification updates.  Libby Avis points out that a moth I had labelled on May 17 as Venusia sp is actually Lobophora sp.  And a caterpillar on May 16, which I had speculated might be Polygonia faunus, has now been confirmed as that species.  I have made the necessary changes to these pages.

 

   On consecutive days, May 18, 19, Derrick Marvin had two of our largest and most spectacular moths in his Duncan garden:

 

 

Smerinthus ophthalmica (Lep.: Sphingidae)  Derrick Marven

 


Hyalophora euryalus (Lep.: Saturniidae)   Derrick Marven

 

 

   Jeff Gaskin reports a latish Sara Orangetip  by the parking lot at Thetis Lake Park, May 19.

    Jochen Möhr writes that on May 14 he saw three Propertius Duskywings at Weir’s Beach, two of them in copula.  He also writes:  I constantly see P. rapae  – up to three simultaneously on my Metchosin property.  I also saw Western Spring Azures on three occasions, without being able to document any of them, and similarly one Sara Orangetip and one Pale Tiger Swallowtail, each on one occasion since the beginning of May.

 

On May 16, he saw on his Metchosin property

1 Erynnis propertius

2 Papilio eurymedon

   Jeff Gaskin writes:  Yesterday, May 16, I did my butterfly count at the Lochside trail north and south of Blenkinsop Lake.  I found a Red Admiral and a Satyr Comma by a patch of nettles about 100 metres south of the bridge.  Another Satyr Comma was north of the lake.  I also saw a Pale Tiger Swallowtail along Arbutus Road later in the day.
