   Apparently you don’t have to go out into wilderness areas to find the Western Brown Elfin.  Annie Pang has found them as close to town as Gorge Park.  Here is one of them, which she photographed there yesterday.

   Jeremy Tatum visited Goldstream Park briefly today, and he saw a few Western Spring Azures and a Red Admiral.  He also checked the Mount Tolmie reservoir at 6:00 pm this evening.  There was one Red Admiral there.

   Mike Yip writes:  Looks like another good year for the Taylor‘s” Checkerspots on Denman Island. I had no trouble finding about 30 right at the entrance to Denman Provincial Park on Thursday May 5.

 

   Today I spent an hour checking some areas a short way past the Saddle parking spot on Mount Cokely and found 5 Sara Orangetips, 6 Hoary “Zephyr” Commas, 3 Western Brown Elfins, 1 Western Pine Elfin, 2 Cedar Hairstreaks, 3 Mylitta Crescents, and several Silvery Blues. The bonus moths [Thank you, Libby Avis, for the identifications!] and ladybird are also from Cokely. After Cokely I checked the Northwest Bay logging road and found many Western Tailed Blues, Western Spring Azures, a few Silvery Blues, and 4 Mylitta Crescents. I was hoping for a duskywing but had to settle for a few dark, day-flying, duskywing-imitating moths. 

 

The Cedar Hairstreak is from my garden and the Moss’s Elfin from Mount Cokely.

   Yesterday we posted a picture of the caterpillar of the moth Coryphista meadii.  Coincidentally, today Rebecca Reader-Lee sends photos of two adults of the same species from the North Highlands.  They both seem to satisfy Jeremy Gatten’s criteria (see April 21) for identifying them.

   Here’s one from Mike Yip, May 2, which I’m afraid that I missed in the pile.  Sorry, Mike!  He wrote that although the lupines were only 10 percent in bloom (probably a bit more advanced by now), Silvery Blues were common.  Here is a pair photographed by Mike at the Horn Lake exit.

 Jeff Gaskin writes:  Today, May 6, I was out on the Lochside trail north of Blenkinsop Lake and I found a Red Admiral. On the bicycling pathway connecting Lochside Drive to Blenkinsop Road, which is south of Blenkinsop Lake, was one Pale Tiger Swallowtail.   Another Pale Tiger Swallowtail was on Mount Tolmie, and my first of year Western Tiger Swallowtail was along Richmond Avenue near Bay Street.

 

    Val George writes: The hot weather this afternoon, May 6, brought out a bonanza of butterflies at and near the summit of Mount Tolmie:  3 Pale Swallowtails, 1 Western Tiger Swallowtail, 2 Painted Ladies, 2 California Tortoiseshells, 1 Red Admiral, 1 Propertius Duskywing (photo attached), and 1 Cabbage White.

   Jeremy Tatum found a spider in his Saanich apartment, and photographed it before putting it out!  Robb Bennett, who kindly identified it, writes:  Philodromus dispar, a male.  Another introduced species here; the males are easily identified by their highly contrasting dark dorsal surfaces and light coloured sides and legs.

   Annie Pang sends a picture of a fearsome male robber fly, kindly identified for us by Rob Cannings as Laphria sp., either L. fernaldi or, more likely, Rob writes, L. asturina, “given the extensive dark hairs on the front of the thorax”
