    Rosemary Jorna sends photographs of three tiny invertebrates from the bark of a maple tree near Kemp Lake, March 3.  To give an idea of their small size, you can see the very tip of Rosemary’s finger at the bottom of each photograph.  Thanks to Dr Robb Bennett for the identification of the spider.  Robb writes:   I think that’s an anyphaenid. We have two species here: Anyphaena aperta and Anyphaena pacifica. Pacifica is more widespread but, around Victoria and Vancouver Island at least, aperta is much more common. And there are many specimens out and about right now.

Rosemary found 13 of the snails. You’ll need to look carefully to see two of them in the photograph.

  Butterfly!  Jeremy Tatum reports the second butterfly reported to Invertebrate Alert this year.  (See February 17 for the first.)   A remarkably fresh and cooperative California Tortoiseshell was on the Mount Tolmie reservoir at 4:00 pm this afternoon, March 5.  It attracted the attention of several people – and a dog – on the reservoir.  The dog made a lunge at it and very nearly caught it.  One spectator cried out: “Look! – a Monarch!”, and was very interested when I said what it really was.  The butterfly was sufficiently cooperative that it allowed Rosemary Weir to crouch down and get her camera within inches of it.  The resulting photograph is shown below.

For those new to the local butterfly scene it is worth knowing that the concrete reservoir on the top of Mount Tolmie is a great place for seeking hill-topping nymphalid butterflies in the late afternoon and early evening.
