   Rosemary Jorna, Kemp Lake, sends a photograph of a spider.  Dr Robb Bennett writes:  It’s an amaurobiid, almost certainly Callobius pictus. The relatively light coloration and the blocky light abdominal marks are usually sufficient to identify this species in our area. The other local candidate, Callobius severus, is very much darker and hairier. Both are common Vancouver Island species, especially in Douglas-fir woodlands.

  Yesterday, writes Jeremy Tatum, we showed a photograph of a butterfly, and I wrote that it was difficult to identify because I could see only the upperside.  Today we have a photograph of a moth, and I write that it is difficult to identify because I can see only the underside.  By this time, viewers will be thinking:  My!  –  Some folks are hard to please !   Well, fortunately Jochen Möhr saw the upperside before he photographed the moth in Metchosin, and saw that it is Xanthorhoe defensaria.

    Jochen also sends a photograph of a pug (Eupithecia sp.)   Pugs can be hard to identify, writes Jeremy Tatum, and I have a bad habit of calling any that look a bit like this one E. annulata.  I’ll resist the habit and label this one “sp.”

   Bruce Whittington sends a photograph of a blue from his Ladysmith garden yesterday.  Since it shows only the upperside, writes Jeremy Tatum, identification was a bit of a challenge, so I am grateful to Mike Yip for examining it critically and confirming Bruce’s suspicion and mine that it is a male Western Spring Azure.

   A few dragonflies and damselflies have been seen in the past few days.  Wendy Ansell writes that she saw her first dragonfly of the season yesterday at Durrance Lake.   She got a few quick snaps of it, not, she feels good enough for posting, but good enough for the first identified dragonfly reported this year.   It was an American Emerald Cordulia shurtleffii.

 

    Rosemary Jorna photographed two snails in her yard near Kemp Lake today:

   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.
