Although there seem to have been few butterflies in the immediate vicinity of Victoria in the last few days, things were better during the May 20 VNHS cycling tour from Sooke Potholes to Leechtown, from which we have received indirect reports of Western Spring Azures, a Western Pine Elfin and various tiger swallowtails, commas and tortoiseshells.  We also heard reports of two possible Milbert’s Tortoiseshells from Hornby Island.  And Geoffrey Newell photographed a Milbert’s Toroiseshell at Maber Flats.  See


Ian Cooper went out in the middle of the night last night to photograph some invertebrates, and he got caught in heavy rain, which did not stop.  This did not deter him, and he carried on to get several photographs, including the ones below.
