   Jeremy Tatum writes:  Have been so busy with Invert Alert recently (a welcome problem!) that I overlooked Val  George’s recent report of his first butterflies of the season, a California Tortoiseshell on Mount Tolmie, and a Cabbage White checking out the kale in his garden in Oak Bay on March 29.

   Gordon Hart writes:  The Green Commas continue here in the Highlands, with three yesterday. We also saw one faded Satyr Comma Polygonia satyrus, a Mourning Cloak Nymphalis antiopa hyperborea and a Moss’ Elfin Callophrys mossii mossii. We have been planting and encouraging more of the Moss’ Elfin larval food plant, stonecrop Sedum  spathulifolium.  Still lots of Epirrhoe plebeculata around, and I will look for Mesoleuca gratulata.
