   Jeremy Tatum writes:  Although I sighed yesterday that no one had reported any butterflies in our area (southern Vancouver Island birdwatching area) in the last two days, and I hadn’t seen any myself, Peter Boon writes from Nanaimo: This weekend was good for butterflies up here. May 1st had my first Pale Tiger Swallowtail fly through the yard and I also saw my first Western Spring Azures in Nanoose at Cross Road. Yesterday,May  2nd,  I saw a beautiful fresh Western Brown Elfin in the yard.

   Jeremy Tatum writes:  No butterflies of moths reported for two days – and I certainly haven’t seen any myself.   I therefore occupied myself with photographing a spider in my Saanich apartment.

May Butterfly Walk Cancelled

Message from Gordon Hart


   Because of the BC Public Health Officer’s ongoing efforts to stop the spread of Covid-19 and its variants, I have cancelled the May Butterfly Walk scheduled for Sunday, May 2.  Hiking outside is still encouraged, so please get out and enjoy the spring weather and look for butterflies. I have not finished compiling our recent April count, but at least eight species were found.
I hope next month will bring better news,
