   Gordon Hart writes from his Highlands home:  There were Cedar Hairstreaks on Stonecrop (Sedum spathulifolium) , and today on the white flat flower umbels of a Viburnum mariesii , there were two Cedar Hairstreaks and two Western Spring Azures, along with a small bee.

Jeremy Tatum asks:  Is there someone out there who can identify the bee?

       Aziza Cooper writes:  Yesterday, June 9, at Swan Lake there was a green dragonfly near the Nature House. A Western Tiger Swallowtail was there too.

At Boas Road near Spectacle Lake, there were two Western Spring Azures, two blue species, one Pale Tiger Swallowtail and one Cedar Hairstreak. The clearcut is very overgrown now, compared with my last visit  in 2017.

At Goldstream Heights, from the end of Olympic Road to the powerline, there were five Cedar Hairstreaks, 20+ Adela, and three Blue sp.

At the railroad tracks near Goldstream campground, there were six Cedar Hairstreaks, one comma, two blue sp., and one Western Spring Azure.
