Jeremy Tatum writes:  During the May 10 -12 Insect Bioblitz in Upland Park, I found a young caterpillar.  It has grown since then, and is now large enough to identify.  Here it is – it is Tetracis jubararia:

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.

Next is a very tiny spiderling. In spite of its minute size, which one might think would be impossible to identify, Ian and Dr Bennett are both in agreement that this is a very young Clubiona.

Female non-biting midge (Dip.: Chironomidae)  Ian Cooper

    Ian found a small caterpillar sharing a cauliflower with him.  It pupated in a silken cocoon, and this moth ecloded (with a d) (emerged) a few days later.
