   Jeff Gaskin writes:  Other than the odd Lorquin’s Admiral and Western Tiger Swallowtail that I’ve been seeing today in Colwood, I saw several Pine Whites. There were 17 that I counted at the Royal Roads University and another 9 along Goldstream Avenue right by the Royal Colwood Golf Course.


   Jeremy Tatum writes:  I visited Swan Lake for about twenty minutes today, and I didn’t see any adult butterflies at all.  However, I found two tiny (3 mm, first instar) caterpillars of Lorquin’s Admiral, both on Ocean Spray. Lorquin’s Admiral spends the winter as a young caterpillar. There were two rather different geometrid moths under the lights at the front door of the Nature House – a somewhat modest Idaea dimidiata and a spectacular Pero mizon.  At 4:00 p.m. there were three butterflies at the top of Mount Tolmie.  A Western Tiger Swallowtail on the reservoir;  a pristine fresh Anise Swallowtail flying around the picnic table area, occasionally settling on the plum tree at the top of the stairs; and a Painted Lady on the roadside next to the Jeffery Pine.

Jeremy Tatum sends photographs of two moths.  Thanks to Libby Avis for identifying the first as Peridroma saucia.  Jeremy reports that he saw a pristine fresh male Satyr Comma at Rithet’s Bog, July 18.  This is the only wild (i.e. not reared from caterpillar) Satyr Comma that he has seen so far this year.

Aziza Cooper writes:  On Sunday, July 17, Moralea Milne and I went out to the logging roads beyond Jordan River and checked a bog where Moralea had seen a couple of Mariposa Coppers two years ago. We found at least 25 Mariposa Coppers in the bog on both sides of the road. Some of the males had the purplish sheen when seen well and every individual we saw was in pristine condition.


We saw two other species: two Dun Skippers and one Western Tiger Swallowtail.


An interesting dragonfly (Crimson-ringed Whiteface) was along a spur road.

At the top there were several Great Arctics. There are still patches of snow at the top.
