Hello, Butterfly Watchers,

This is a reminder for the VNHS Butterfly Walk on Sunday, July 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, and depending on the weather, we will decide on a destination from there.

You can review Vancouver Island butterflies at Val George’s website : https://vancouverislandbutterflies.com/

See you on Sunday,

Gordon

Jeremy Tatum writes:  The tops of Mount Douglas and Mount Tolmie were very active with butterflies at around 5:00 pm this afternoon.  At Mount Douglas there were Pale Tiger Swallowtails, Anise Swallowtails, Painted Ladies and one (or more) West Coast Lady. Strangely, no Western Tiger Swallowtails or Lorquin’s Admirals at the top, though there were plenty of those in Bow Park. At Mount Tolmie, there were Western Tiger Swallowtails, Lorquin’s Admirals, Painted Ladies, a Red Admiral and at least two West Coast Ladies.  BTW, if you visit Bow Park, take a close look at any Cabbage White that you might see – just in case it isn’t one.  I have twice seen white butterflies that I wasn’t quite sure of.

 

Today I visited the aspen at Cattle Point where Marie O’Shaughnessy photographed (see June 16) a number of young Mourning Cloak caterpillars.  I found them still all together on the same aspen leaf, apparently without having eaten or grown.  I concluded that this was because at Cattle Point it is nearly always windy and the aspen leaf was all the time trembling like a Trembling Aspen leaf leaving no time for the caterpillars to do anything other than hold on for dear life.   I have therefore transferred the caterpillars to an aspen in Bow Park, where it is much less windy.

 

Invertebrate Alert currently has a large backlog of photographs, some of which are awaiting identification, so there may be some delay in posting them.
