Jeremy Tatum writes: Shortly before ecdysis (skin-change from one instar to the next) the caterpillar of a butterfly or moth typically appears “two-headed”. The head of the “new” caterpillar is withdrawn into the thoracic area of the “old” skin. The first (foremost) head that you can see is the now-empty head capsule of the “old” caterpillar. Behind this you can see the head of the “new” caterpillar inside the ”old” skin. We see in the photograph the “double-head” of an eyed hawk moth caterpillar shortly going to change from fourth instar to fifth.

Ian Cooper photographed these two spiders in the middle of the night (August 27/28) at Colquitz Creek Park. We thank Dr Robb Bennett for confirming Ian’s accurate identifications. Of the first, Dr Bennett writes: This is a clubionid, a species of Clubiona. There are quite a few species in BC but I suspect this one is the introduced species Clubiona lutescens.

Just before presstime, we heard from Jeremy Gatten that he had seen a Swift Forktail yesterday by the Vancouver Island Trout Hatchery close to the Cowichan River in Duncan. In case anyone is wondering, that’s a damselfly, Ischnura erratica.
